    Good day Eden2013, 

    To help me better understand the situation and assist you effectively, could you please share a few details such as:   

    1/ Are you trying to add your work account to both Outlook desktop app and Outlook for Android, or only to Outlook for Android? 

    2/ If the issue also occurs in Outlook desktop app, are you using New Outlook or Classic Outlook, and is your device running Windows or macOS? 

    3/ Please share the exact error message or a screenshot from both Outlook desktop app and Outlook for Android. (Make sure to blur or cover any personal or sensitive information in the screenshot to protect your privacy) 

    This will help me better understand the context and provide more targeted support. Any additional information will help me better understand and support you.    

    You can also review these setup guides while gathering the details: 

    Set up email in the Outlook for Android app | Microsoft Support 

    Add an email account to Outlook for Windows | Microsoft Support 

    Once you share the error details, I'll be able to provide more targeted troubleshooting steps. 

    I look forward to your response and hope to hear from you soon.

    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.
