Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error.

What is this particular error?

One common issue when trying to upgrade to Windows 10 from Windows 7 or 8 is incompatible software. Any installed software or app that isn’t compatible with Windows 10 will prevent you from continuing with the set-up. Normally, you’ll get an error message “What needs your attention” and it will ask you to uninstall a list of apps manually. Unfortunately, some users reported that they couldn’t find the app it asks to uninstall. In some cases, users said they’ve already uninstalled the app but it still won’t start the Windows 10 Setup.

Solution

Error Causes

This type of issue normally occurs because of the following:

• Incompatible software/apps
• Corrupted software/apps
• Incomplete uninstallation

Further Information and Manual Repair

Here are some steps you can take whenever you encounter this error.

Note: Before taking any steps, make sure that you’re highly equipped to do so. Some steps might affect the system and even do more damage to your computer. You might also want to consider using an automated tool instead.

Method 1 – Perform a clean boot, then retry upgrading

A clean boot is normally done to start Windows using the least set of drivers and startup programs available. By doing this, it eliminates possible software issues that happen when installing or uninstalling a program in Windows 10.

Before performing a clean boot, make sure to take note of the following:

• You need administrative privileges in order to perform this action.
• When doing this, your computer might lose temporarily functionality. However, it will return after start-up.
• It is highly advisable to not use the System Configuration to change advanced boot options.

Here are the steps to perform a clean boot.

• Step 1 – Go to Start and search for msconfig
• Step 2 – Go to System Configuration
• Step 3 – Under Services tab, click on the “Hide all Microsoft services” checkbox. Then, choose to Disable all
• Step 4 – Go to the System Configuration’s Startup tab. Then, click on “Open Task Manager”
• Step 5 – In the Task Manager dialog box, you will see a Startup tab. Choose items that you want to disable and then click the Disable button
• Step 6 – Close the Task Manager dialog box.
• Step 7 – Go back to the Startup tab of the System Configuration box. Click “Ok” then proceed with restarting.

Method 2 – Manually uninstall programs from the Program Files folders

Instead of using the “add or remove programs” feature in Windows, you might need to manually install the program directly from the C drive. To do this, follow the steps below:

• Step 1 – Go to the C drive, and look for the Program Files folders. For 32-bit users, you can find it at C:\Program Files. If you’re using the 64-bit version of Windows, go to C:\Program Files (x86) folder.
• Step 2 – Find the “uninstall” application file
• Step 3 – Right-click, and run the file as administrator. Wait for the uninstallation to finish. In some software, you need to restart your system before the uninstallation will take effect.

Note: In some cases, you may also need to search for files related to the program. You can use the search bar under Drive C to do this. Delete those files as well.

Method 3 – Create a new user account

Before upgrading to Windows 10, create a new user account. Make sure it has administrative privileges. From there, run the upgrade.

Method 4 – Use third-party uninstaller services

If you still can’t run Windows 10 Setup after the above methods, you might need to rely on a third-party service. Microsoft recommends Revouninstaller that can help you.

Before using this software, reinstall the application or utility that Windows 10 wants you to install. Then, use Revouninstaller to delete the program completely.

Method 5 – Disable third-party antivirus software

Some users who experienced this issue reported that it was solved after disabling or completely uninstalling the anti-virus software installed in their system.

Method 6 – Use a trusted automated tool

If after trying the above methods, the problem still persists, it might be best to use a trusted automated tool to fix the issue.

If you suddenly encounter an error message saying, “ File Record Segment is Unreadable ” on a blue screen while booting your PC, it means that your hard drive is in an error state. This particular blue screen of death error might have a lot of bad sectors or might have reached its end. The workarounds you can try to resolve the issue is by locating the bad sectors or checking your hard drive for any discrepancies in the mapping and fix them. Follow the detailed instructions laid out below for these workarounds.

Option 1 – Try to check for any bad sectors and wrong configurations in your hard drive

The first thing you have to check is the boot files on your PC. As you know, your PC boots from these files and if there is anything wrong with any one of them or if one of them ends up getting corrupted, you will most likely see the blue screen of death error or a prompt with an error message saying, “File record segment is unreadable”. According to some users who reported this issue, new hard drives aren’t exempted from this error. That’s why it is recommended that you carry out this solution no matter what kind of scenario you are in. You will have to launch the Command Prompt in recovery mode and see if you can fix the problem by executing the check disk commands.

• Upon booting, restart your PC and tap F11 to go to the recovery environment then select Troubleshoot.
• Next, click Advanced from the given options and select Command Prompt.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed. And depending on the situation, it might even take a day at most so patience is really the key here.

Option 2 – Try connecting the hard drive to a different computer

If option 1 didn’t work for you and you’re still seeing the error, you can try connecting the hard drive to a different computer and then copy the data first. Make it a priority to salvage the data just in case the hard drive won’t make it in the future. After replicating your hard drive, you can then try running the chkdsk commands that are listed in option 1 above in the new computer you’re connecting your hard drive to and make sure that you key in the correct drive letter that’s assigned to the hard drive you’re using. After executing the chkdsk commands, plug your hard drive back into the previous computer and then check if you can now boot it without any issues.

Option 4 – Replace the faulty hard drive

If none of the options provided above really worked out then maybe it’s time to consider getting a replacement for your hard drive. In about 50% of the cases about this error, some unfortunate users were left with no choice but to replace the hard drive since the problem is with the hard drive itself. Hard drives have a complex running mechanism which includes a head and the disk that rotates accordingly so you can check if the cables connected to the hard drive are connected properly and if it is in a correct position or not. In addition, you also have to make sure that the SATA adapters where the hard drive is connected are working properly. If the drive is showing problems in the I/O operation, there is little chance for you to use it as a normal hard drive. If the hard drive is in warranty, get it checked and replace it. If not, you might consider taking it to the service center for the specialists to take a look into it.

If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
2. An issue with system maintenance could cause the problem.
3. Malware or some other software might have created an undetectable hidden file.
4. Space could be occupied by the trashbin folder.
5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
6. Run ChkDsk
7. Clear all Junk files
8. Reduce the space occupied by the system restore points
9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:

• In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
• Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
• After that, click on the System Maintenance troubleshooter to run it.
• Once the process is completed, restart your computer.

Option 2 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in msconfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

Option 3 – Clear the contents of both the SoftwareDistribution and Catroot2 folders

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

 Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 4 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80070020. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Try restarting the Windows Update Services

• Open the Services Manager.

From there, make sure that you set the following services and Startup types:

• Background Intelligent Transfer Service: Manual
• Cryptographic Service: Automatic
• Windows Update Service: Manual (Triggered)
