Reproducing the Issue

  1. Start MS Outlook.
  2. Hit on the icon of SAP Outlook Add-in in the ribbon.
  3. The SAP Outlook Add-in keeps loading continuously and never stops.


The MS Office cache may conflict with the Outlook Add-in's because of an MS update.


  1. Open File Explorer on your computer.
  2. Go to the folder by the path "%LocalAppData%\Microsoft\Office\15.0\WEF". For MS Office 2016 or later versions, the path would be "%LocalAppData%\Microsoft\Office\16.0\WEF".
  3. Clear the content of the folder.
  4. Restart MS Outlook.

*Note: If the resolution is not working, please raise an incident ticket to the support team.
