We recently tested the Timetable software calendar Outlook 2016 integration (ie importing .ics file into Outlook calendar. Since then we cannot stop calendar pop-up notifications even after deleting the imported calendar entirely.
So far we have tried:
Command line switches Outlook - run exe /cleanreminders
Used MFCMAPI tool to delete remainders folder
Removed and recreated MS Outlook profile
Still, no luck resolving the issue.
Please let me know if you have any other suggestion.
