Hello all, I have a rather odd issue concerning Outlook 365 and IMAP. I setup a new laptop for a friend. Windows 10 PRO. We installed a fresh copy of Office 365 and setup her work email which is IMAP. Everything seemed ok. Then this morning she called saying emails were stuck in her Outbox. So I remote into her PC and sure enough. The only way I can get her email to send is if I right click on the email and select Forward. Then put the recipients email address in to the CC field and it will send. Then I have to delete the original email from the Outbox. Thoughts?
