Version 15.0.60930 I have my "Import Contact" set to "synchronize with Office 365 Account". When I connect it and press the "Sync-button", I get the message "Sync successful". This is how it should be ... But always (after some hours or some reboots or some days ????) the sync is disconnected and I have to start the Sync again. Is this "by design". I suppose that a (setting for a) connection stays always connected? What to do to keep it always connected?
