SilvanNagl 2023-09-28 07:49 reporter ~0017318	For months this problem now eats our resources. We would really appreciate to find a solution for this.

qhivert 2023-09-28 10:00 administrator ~0017320	Hello, Could you do the same as here https://github.com/mailcow/mailcow-dockerized/issues/5045#issuecomment-1615833182 and add SOGoEASDebugEnabled = YES to your sogo.conf, wait for the problem to appear and give us the log? (by default /var/log/sogo/sogo.log) And also what version of iOS do you have?

SilvanNagl 2023-10-25 12:50 reporter ~0017400	Yes, the bug is identically to mentioned comment. mailcowdockerized-sogo-mailcow-1 \| Oct 25 14:49:47 4991662df76e sogod [57]: <0x0x56383afe8b40[SOGoActiveSyncDispatcher]> EAS - request for device 72T5A34GMH0MP16ASAC83JT8UG: <?xml version="1.0"?> mailcowdockerized-sogo-mailcow-1 \| Oct 25 14:49:47 4991662df76e syslog-ng[11]: Error processing log message: <!DOCTYPE ActiveSync PUBLIC "-//MICROSOFT//DTD ActiveSync//EN" "http://www.microsoft.com/"> mailcowdockerized-sogo-mailcow-1 \| <Sync xmlns="AirSync:"> mailcowdockerized-sogo-mailcow-1 \| <Collections> mailcowdockerized-sogo-mailcow-1 \| <Collection> mailcowdockerized-sogo-mailcow-1 \| <SyncKey>0</SyncKey> mailcowdockerized-sogo-mailcow-1 \| <CollectionId>mail%2FShared</CollectionId>
