To enable an inactive add-in that keeps unloading on restart in Outlook you should follow these steps:

First shut down Outlook, then uninstall the software providing the add-in from your machine.

Then go into regedit whilst logged in as the affected user and go to the following location:

HKEY_CURRENT_USERSoftwareMicrosoftOffice15.0OutlookResiliency

Delete the REG_BINARY keys found in DisabledItems and CrashingAddinList folders:

Then navigate to this location:

HKEY_CURRENT_USERSoftwareMicrosoftOfficeOutlookAddins

Then delete the key (folder) that references the add-in (we are using Mimecast as our example below):

Reinstall the software that provided the add-in and then restart Outlook. The add-in should now load.
