I have an issue where user 1 has access to a shared mailbox. User 1 was moving an email from the inbox of the shared mailbox to a different folder inside the shared mailbox, then her outlook crashed.
The email was successfully moved to the different folder but it seems to be stuck in the mailbox. When you click on the email it says
"this item cannot be displayed in the reading pane. Open the item to read its content."
When you double click the mail it cannot be opened.
I have recreated the users outlook profile which didn't fix it.
