UserA wants to share calendar with UserB. I select properties on UserA's calendar and go to permissions. I add UserB to the list and give them editor rights, then save and close. I reboot both Users machines. I open UserB's Outlook and open the shared calendar and get the following error "The calendar folder could not be found". I verify that UserB is in the permissions list (and she is, with editor permission).
What could be the problem?
Note: I have taken the exact same steps with a different user (sharing UserC with UserB) and it works. Furthermore, I have tried same steps with yet another user (sharing UserA with UserD) and the same error is reported on UserD's Outlook. Seems like there is something wrong with UserA's calendar (since sharing works with all other scenarios).
