I am awaiting an URGENT email from my school and Microsoft will not let me sign into my school email with Outlook at Seminole State College. I am trying the phone app. Not working. It is not working on my laptop either. This is very important. Thank you.

Hi @Nainika Kishan,

Thank you for posting your question in the Microsoft Q&A forum.

Regarding that you can't log in to your email due to Error code 500. To help narrow down the root cause. I’d like to ask some quick questions to better understand your situation and assist you effectively:

Could you please confirm whether you have already checked with your administrator to ensure that your account still has an active license?

If you have admin privileges, you can verify this by following these steps:

Sign in to the Microsoft 365 Admin Center: https://admin.microsoft.com/
Go to Users > Active users
Select your user account
Choose Licenses and apps
Expand Apps and ensure that Exchange Online (Plan 1 or Plan 2) is enabled

If the license is already assigned, try unchecking it, saving the changes, then reassigning it. Afterward, wait for the synchronization to complete and check if the issue is resolved.

If you don't have Admin privilege, kindly contact your organization Admin to check above for you.

You may also can refer to this link : Getting a mailbox not found error in Outlook on the web - Microsoft 365 admin | Microsoft Learn.

If the issue still present, you may also (use admin account to) go to Office 365 Admin Center-> Support-> New Service Request. The support engineers there have the correct escalation channel, and this is the most efficient way to report such issue. You can refer to this article to check the way how to raise a ticket: Ways to contact support for business products - Admin help. The engineers in related team have higher permission and resources than us to help check the root cause from background directly.

Thank you again for your time and understanding. I really appreciate your patience, and I’m here to help. Looking forward to your response.
