Not sure if this is an Outlook or Exchange issue.
PA has had her delegate rights for managers inbox upgraded from Reviewer to Owner while manager is on vacaction to clear the crap. She has reviewer rights at root of mailbox as is usual for a Delegate.
For some reason she cannot delete any messages from her managers inbox, she can move them to a sub-folder where she has editor rights but cannot delete from there either.
We have a workaround where she'll move the messages to her own Inbox and delete them from there but would be nice to know why this might be happening.
