After updating to Gromox 3.1.27.gd5eef7c-lp156.10.1 (openSUSE Leap 15.6), Outlook for Mac 16.102 frequently drops the EWS connection.
Rolling back to 3.1.0.gbcd1157-lp156.1.1 fixes the issue immediately.
No config changes were made between versions.
Steps to Reproduce
sudo zypper update -y → install 3.1.27
Start Outlook 16.102 on macOS
Observe repeated disconnects (“disconnected” status, sync errors)
Expected Behavior
Stable EWS connection without interruptions.
Actual Behavior
Outlook connects briefly, then drops connection repeatedly.
Downgrade to 3.1.0 restores stability.
Environment

Gromox: 3.1.27 (broken) / 3.1.0 (working)
