Use IMAP on every device and map sent, drafts, junk and deleted mail to server-side folders.

Applies to: Hosting mailboxes used on two or more devices

Set up synchronisation

Confirm webmail shows the current server-side folders and messages.
Configure each device as IMAP using port 993 with SSL/TLS.
Use authenticated SMTP on port 587 with STARTTLS.
In each application, choose the server-side Sent, Drafts, Junk and Trash folders where folder mapping is offered.
Send, read and delete a test message on one device.
Confirm the same state appears in webmail and on the other device.

Avoid data loss

Do not mix POP and IMAP unless you understand which device may remove the server copy.
Export local-only folders before deleting an old account profile.
Allow large folders time to synchronise before making further changes.
Monitor mailbox and hosting-plan storage.
