I am not able to send emails. Unsent emails are sitting in my Outbox. The message says can’t send due to full mailbox. I have trashed my deleted emails and then deleted my trashed emails. What am I missing?
iPhone 8 Plus, iOS 14
Turned out that I had to empty folders on Outlook which resolved the problem.
thanks
