Hi @anstifter ,
Admin can perform the mailbox audit process.
Hopefully, it helps to find the root cause.
We have a room calendar in a hybrid environment that up until last Wednesday was filled with several appointments.
When a user (delegate, send on behalf permission) set up a new meeting he discovered that all previously booked appointments are missing.
Since the mailbox is set up as a ressource there doesn't seem to be a way to find any items to restore. One admin gave himself full-access permission, but couldn't find any items to restore.
Is there a way to find
a) the missing items &
b) out what happened?
