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

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.

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.

Steam Deck release is almost upon us and more news comes to light. The Latest officially confirmed technical detail is that the user will have access to device's BIOS and that dual booting will be officially supported. This, of course, means that you will be able to have both Proton and Windows on your device letting you play anything that you wish if the hardware is strong enough. Valve also said that you can launch OS from an SD card! This of course will save space available for games themselves, especially for entry models with less than one available. All of this information really pushes Deck into the territory of a handheld PC and not just another console and I must admit that this announcement left a smile on my face.

It can lead to system crash and failure, due to which you can also lose your valuable data stored in your system. How to Fix IRQL_NOT_LESS_OR_EQUAL Error Code?

Further Information and Manual Repair

Here are some of the best and easy DIY methods to resolve this error code on your PC:

1. Roll Back Drivers

If the underlying cause of IRQL_NOT_LESS_OR_EQUAL error is poor driver installation, then try this method to resolve the issue. This can be done by simply clicking the start menu. Once you click on it, go to the control panel, then double click the system icon and locate the System Properties window. After that, click the hardware tab and then the device manager button. Now locate the device you recently installed. Double click on the recently installed device driver, click the driver tab, and then the rollback driver button. This will take a while, so wait for the process to finish.  After that, reboot the system.

2. Run Hardware Diagnostic

The IRQL error may also be triggered by faulty hardware. To identify which hardware is causing the error to pop up, you will have to run a hardware diagnostic.

• For this, go to the start menu, type Memory Diagnostic in the search bar.
• Now access this tool and click on Diagnose your memory problems. As you click it, it will ask you to perform the check by either restarting the PC immediately or on the next restart.
• Select the immediate one to get going. The system will carry a scan on the memory and show you the list of problematic errors detected during the scan. To resolve this error then all you have to do is replace the piece of faulty hardware.

Nonetheless, if no faulty hardware is detected, this means the error is related to memory. If so, try method 3 to resolve.

3. Disable Memory Caching

To fix the IRQL_NOT_LESS_OR_EQUAL error, try disabling the memory caching option. This is called BIOS memory caching. This can be done by restarting your PC and pressing the BIOS setup keys to enter the settings screen. Mostly it is an F2 key, however, it may be different in some computers as the motherboards of different makes have their own respective keys. Once you enter the BIOS settings look for options stating memory settings. Access these options and disable the memory caching feature.

4. Scan your PC for Malware

As mentioned above this error message can also result due to the intrusion of malicious software like malware, viruses, and spyware.

5.  Repair Registry and Fragmented Disk

Due to poor PC maintenance, you may experience registry issues. The registry stores all the activities performed on the PC including the unnecessary pieces of information like junk files, internet history, temporary files, cookies, and other flies. Such files take up a lot of disk space. When there is not much space on the storage device, the new data is saved in fragments. This is called disk fragmentation. When this file becomes fragmented it takes time to rearrange the data and reunite it to run the fragmented file on your PC. If not resolved, this leads to registry issues and thereby generating various PC error codes including IRQL_NOT_LESS_OR_EQUAL errors. The best way to clean the registry and repair the fragmented disk is to download Restoro. This is an advanced and multi-functional PC Fixer. It is embedded with multiple system repair utilities including a powerful registry cleaner that detects all registry issues in seconds, removes and wipes out unnecessary files cluttering the registry, cleans and repairs the registry and the damaged files.
