I have an IMAP email account active on both my home and work computers (both Macs). The problem I am having is that when the emails are downloaded onto both computers from the server, if I delete an email or move it to a folder, on one Mac, it then disappears completely from the Inbox on the other one! The two computers are not linked in any way, and the email account is set up exactly the same on both computers using the same username and password. I can’t see any setting that gives an indication that it will delete an email if it is moved from the Inbox of another computer. Also, other colleagues who have the same email account set up on their computers, don’t lose any emails from their Inboxes when I move them from mine. They, however, are using Windows PCs not Macs. Any thoughts or help would be much appreciated. Thanks!
I'm sorry but you're getting it wrong. This is the expected behavior of IMAP. IMAP is to keep all devices synced with the server. That means, if you delete an email on one computer, it eventually disappears from all the others. If you mark something as read on one computer, it eventually gets marked as read on all of the others. I hope this clears things up.
I would suggest that your colleagues are likely setup to use POP3, and not IMAP. POP3 does not synchronize, IMAP does.
