We have a weird fault that started on the 7th Feb. Using Outlook OWA on Edge. The user has a shared mailbox in her list and she wants to move some emails to her personal mailbox. In the past she has just dragged and dropped the email and it has moved. Now when she drags and drops (and also using the move option) it copies the email, leaving the original in the shared mailbox.
Any idea why you can't move emails, only copy? Can't find a setting for this and neither can I produce a good enough search term for google to find some help.
