I removed the Mail (Apple) App from my Apple iPhone. Re-installed from the cloud.
For me the issue on both my Virgin net email accounts was that the INCOMING MAIL SERVER Username had "recent:xxxx.x.xxxxx" instead of " email@example.com" .... the "@virgin.net " had disappeared.
When I tried to re-enter it didn't like the "recent:" anymore. So I removed that. The is now just "firstname.lastname@example.org". Account then verified (when I hit Done.)
And slowly my inbox rebuilt on my phone. 250 messages at a time.
For several years I have used the prefix "recent:" on my incoming server so that emails would both download to my phone and my home computer once. So that I had emails on both devices. Deleting from one device didn't delete from the other. I have delete from server never switched on. I think I read somewhere that thi is now the default setting for VM emails anyway so no need for the "recent:" prefix.
Can I recommend that if you are using multiple devices to access the same email account that you STOP using POP3
The recent: thing has been covered in other threads. It was a Gmail specific addition that does nothing on normal email servers, It USED to be removed quietly on login but VM have recently changed their setup.
IMAP is the recommended mail protocol if you are using multiple clients. Not least as POP3 doesn't see all the folders on the server.
