    The issue is likely caused by an Outlook add-in hanging during send. Disable the add-in by starting classic Outlook in safe mode and then turning off the problematic add-in.

    Follow these steps:

    1. Close Outlook.
    2. Start Outlook in safe mode so all add-ins are disabled:
      • Press the Windows key.
      • Type outlook.exe /safe and press Enter.
    3. In safe mode, try sending a test email.
      • If the email sends successfully, an add-in is causing the problem.
    4. Disable add-ins in normal Outlook:
      • Close Outlook and reopen it normally.
      • Select File > Options > Add-ins.
      • At the bottom, next to Manage, select COM Add-ins and choose Go.
      • Clear the check boxes for all add-ins (especially the one shown in the message) and select OK.
      • Restart Outlook and test sending again.
    5. If sending now works, re-enable add-ins one at a time, restarting Outlook and testing after each, until the failing add-in is identified. Leave that add-in disabled.

    If emails still will not send after disabling add-ins, repair the Outlook profile and program as additional steps:

    1. Repair the Outlook profile using the steps in Fix your Outlook email connection by repairing your profile.
    2. If needed, repair the Office installation using Repair an Office application.
