issue to connect my professional email to outlook

For a professional email account in Outlook mobile, use this troubleshooting path:

1. In the Outlook app, go to Settings > tap the account if it appears > tap Reset Account.
2. If that does not work, remove it and add it again:
   • Settings > tap the account > Delete Account > Delete From This Device
   • Add the account again in Outlook.
3. If Outlook prompts to add the account as IMAP or POP, calendar and contacts will not sync. The account must be added as Exchange ActiveSync or Exchange.
4. If Outlook asks for manual server settings, get the correct server settings from the email provider or administrator.
5. On Android, also check the device account settings:
   • Settings > Accounts > tap Exchange > tap the email address
   • Make sure Sync Calendar is enabled
   • If the account shows as IMAP instead of Exchange, remove it and add it again correctly.
6. If the account is a Microsoft 365 work or school account, contact the Microsoft 365 admin or technical support. Some sign-in failures on work accounts are caused by organization authentication requirements or tenant-side restrictions.
7. On some Android devices, Outlook mail add/sync issues can be caused by power-saving or app optimization settings when Microsoft Authenticator or Company Portal is installed. Turn off power-saving mode, disable power optimization for Authenticator/Company Portal, and open Authenticator/Company Portal before opening Outlook.
8. If the error is an SSL certificate mismatch, that is an email service/provider issue. The provider or IT admin must fix the certificate domain mismatch.

If the account worked before and now stopped syncing, remove the sync partnership and re-add the account.
