Consider using the following fixes to fix Outlook Error 550 and send your emails successfully:
#1. Check your Email Address Twice
If you receive error 550, you don’t need to worry. When you type the recipient’s email address wrong, the error notice almost always shows. Make sure the recipient’s email address is correct in this instance by checking it twice. If not, confirm that you have typed in the correct address and begin sending the email once more.
Try a new approach if the issue persists.

Incorrect SMTP settings can also result in Error 550. Adjust Outlook as necessary to resolve the problem. Navigate to the Tools and Accounts section in the Outlook settings to accomplish this. Select View/Change Email Account after selecting the e-mail address that is giving you difficulties.

#3. Internet Service Provider Restrictions
Error 550 can also be caused, though less frequently, by ISP (Internet service provider) blocking. The SMTP server is instantly limited by network managers if the junk email folder gets full in order to prevent spam on the network. To fix the issue if this is the case, get in touch with your internet service provider’s management.
#4. Clean the machine of any viruses and malware.
Error 550 is sometimes caused by malware and viruses. Thus, eliminate every virus, malware, Trojan horse, and spyware. Make sure your firewalls are turned on and up to date, and you can accomplish this with any antivirus program.
