Window Mail has not synced since 3/7/2017 AM

Have you tried removing one of the account and adding it back again?

Re-adding might force the account and app to sync.

Same issue since the March 2017 updates.  Mail App WILL NOT sync any folder unless I sync them manually.  I cant receive, send, delete, archive, etc.. unless manually clicking on the sync option.  I use Outlook (web).. never any trouble before these "updates" pushed through.

HELP!  Mail App has become pointless.

Found this help page, might help (specially the Change your privacy settings)

Thanks.  Found that before and it did not help. My only hope is for Microsoft to put out a new update that fixes this problem.  I wonder if MS is customer centric enough to actually read these posts and follow through.

Sucks to go through this with a one month old computer.

Didn't help for me either.  MS fixes are the common "minor sync" issue fixes written 2 years ago.

Their feedback hub has 1000's of complaints on this... and the Windows Store feedback (most recent feedback) is in the 100's.  But if you want to see that, go the left of your screen and click on lowest ratings (when you go to the App within the Win Store... and I strongly urge everyone to provide their own feedback in both places).... MS just wont listen otherwise.

I too have had the same issue since the March updates - have spent hours trying to resolve it - emails come in perfectly to my phone and tablet but not to the laptop unless manually syncing them.

Also seemed to coincide with a message on screen saying outlook.com supports focused inbox forcing a Focused inbox on us - which I have switched to off now as didn't like having to check and refresh email boxes within 2 email accounts so time consuming!! Please can someone help us. Emails are set to display as they arrive and sync is put to on !! it's enough to drive you mad!!!
