Using classic Outlook for Windows in business environments
Hello LauraS_043
Thank you for posting in Microsoft Community.
I understand that you have an issue in your Outlook.com wherein you encountered an error code. Let’s work together in finding the best resolution to this issue.
For me to better understand the issue, I’d like to ask a few questions:
- What are the changes made to the account prior of having the issue?
- Have you tried to open it in-private mode in a browser?
Outlook Error 500 can be caused by various issues such as mailbox not found, protocol disabled, or too many roles assigned to the user. To fix the error, you can try the following solutions:
- Check service health.
- Manage roles of users.
- Enable Outlook on the web.
- Create a new Outlook profile.
- Repair Outlook data files.
- Run the /resetnavpane command.
- Use the InPrivate mode of a different browser to log in to the Outlook web APP
If none of those solutions work, you may need to reinstall Outlook.
We look forward to your next response.
