Active Sync stops working. (Outlook 2016 & 2019) #6968

since some days i got some problems with a new Sync of my Outlook 2019 and 2016.

First the sync works very fine but then it stops. After this Outlook is saying, that the folder is up to date. But this is wrong, because many of my E-Mails are missing.

In the webinterface the folders are really up to date. So it seems to me, that is something wrong with my devices.

Someone got the same problem?

Thanks a lot for helping me.

Thanks for helping me.

The file tine20.log only show the following things. But i can not see a failure. And the PHP Error log shows nothing.

The Only Error is shown on Apache.
=> Message:
POST /Microsoft-Server-ActiveSync?Cmd=Sync&User=example&DeviceId=50FADC93791F49458777XXXXXDDA13B&DeviceType=WindowsOutlook15 HTTP/1.0 --

This is a short extract of the tine20.log:

looks like there is a permission problem: the webserver might not be able to read all files below /var/www/vhosts/ could you please check that?

Hi I'm working on the Server together with @anio89.

I've checked the permissions and they are set to 0644 with the right user and Group.

Curious is, that active sync works an Android and iOS devices. only MS-Outlook has a Problem.

Any other suggestions? Thanks a lot!
