Public Folder Calendars will not add as favorites in Outlook on the web AGAIN

[ChristineStack]

Public Folder Calendars will not add as favorites in Outlook on the web AGAIN.  Last time I spent 3 hrs working with MS support before they escalated this issue and it was listed in the health status as an issue.  Is anyone else having this issue?  This person's account is an owner of this public folder.  Others have access via Outlook 2016 as does this user.

Seems to work fine in my tenant, the only time I get an error is when the PF is already added to Favorites. Can you add it from Outlook?

Very embarrassingly.... The calendar was already there.  My guess is it was not available as reported by the user and he put it back as a favorite and it started working.  I never looked for it by just tried adding it as a favorite.

Well in all fairness, that error message can certainly be handled better 🙂
