Hi,
Thank you for posting your query on Microsoft Community.
To assist you further could you please confirm a couple of things:
- Did you make any recent changes to your Phone?
- Have you tried to check if the issue occurs using another account?
This issue normally occurs due to bad caches and bad settings after the update. As an initial troubleshooting, you need to clear your mobile cache, remove (make sure to
turn off the automatic update), and reconfigure your account. Refer to the link below for more information:

If your email app supports Exchange ActiveSync and you need to configure it manually, use the following settings:
- Server address: s.outlook.com
- Domain: <leave empty>
- User name: Your email address
- Password: Your password
- TLS/SSL encryption required: Yes
Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.
