You don't have permission to create an entry in this folder

[Guest]

One of our users is having this problem with his email, and we have had no
luck figuring it out. This message appears when he tried to open items in
any folder other than his inbox. No permissions have been changed and when
we added Owner, that didn't seem to help it. Anyone else run into this
problem? We've detected and repaired and reinstalled and deleted the profile
to no avail.

Thanks

Exactly my problem today and since the last round of
update.microsoft.com patches.

Any insight into this issue?

Cannot delete any "sent messages" and I cannot use the calendar at all
