My Galaxy S6 auto updated to marshmallow over the weekend. Since then my Hotmail e-mails no longer auto-synch, I have to manually update. I have tried:- 1. checking that auto-synch is turned on for both the e-mail app and the phone. Tried turning it off and on a few times which is often suggested as a solution 2. deleting the account from mobile devices settings in Outlook for Web and restarting phone (with a cache wipe) 3. removing and re-adding the Hotmail account to the default e-mail app. 4. removing the account from default app, downloading Outlook app and using that. 5. Tried 2 again having done 4 for the new mobile device account. I only have the 1 e-mail account running so no clashes with other accounts. Nothing is working. I have to manually check for new e-mails. The new Outlook app always flashes up an "unable to connect" message before pulling down the new e-mails. E-mail worked just fine prior to the system upgrade. Any other solutions I should try?
