Rename category greyed out for mailbox delegate
Hi I have an issue with a user who came to me and said she could not rename a category in a calendar. After looking at this the user was a delegate to a shared mailbox in Exchange Online. She had...
Just to let people know. It turns out the article means shared personal mailboxes not shared (ie multiuser) mailboxes. Microsoft confirmed this via a case I raised.
I hope they make that more explicit in the support article.
Full access grants you higher set of permissions compared to Editor, so this shouldnt be the case. My bet would be it's because you have the mailbox automapped or the calendar added from the "open another calendar" menu - in such cases only a limited subset of Outlook functionalities will be exposed. Instead, add the shared mailbox as additional account (via File -> Add Account -> enter the shared mailbox address -> enter your credentials when prompted).
VasilMichev I will take a look. Although I would be a little surprised. In Exchange Online the shared mailboxes are unlicensed so logging onto them as a mailbox would seem the same as "Open another mailbox" from the web. We tried that and it didn't help. Just my thought.
My own test tenant worked fine with automapping so again I am not sure. However, at this point I don't dismiss anything.
