Using Mail 7.3. (OSX 10.9.5) - Emails is set up through our web site hosting company. I have a Flagged folded on iMac that is under "Mailboxes" and this folder not listed under the Email "[email protected]" = my ISP. The Flagged folder count is never synced with iPhone or iPad. Would anyone know how to set up Flagged folders in IMAP that would sync with all 3 devices?
