Known issue: CRM for Outlook throws an error during startup

Update in 2021.11: If you get this error, please update to the latest CRM for Outlook version.

You might get an error that states the following during the startup of CRM for Outlook:

CRM for Outlook encountered an unexpected startup error: System.Runtime.InteropServices.COMException (0x84140111): Exception from HRESULT: 0x84140111 ...

If you get the error, it's usually connected to a .pst archive in Outlook client that cannot be found. To fix the issue, unlink the .pst file from the Outlook client and restart the client.

If that doesn't fix it, please check how many profiles there are registered in the Outlook client (check all of them) and if any of these contain property information for either email or data files that no longer exist.

If there are records that don't exist anymore, please delete them and restart the Outlook client.
