Outlook 365 (Enterprise) new message audio alert no longer works

It's difficult for me to troubleshoot the problem since I don't have access to Outlook 365 for Enterprise. Also, it's quite surprising if 7+ Taskbar Tweaker causes such an incompatibility, it shouldn't affect other apps.

Perhaps try disabling all of the tweaker's options and see whether the issue goes away. If it does, try to find out which of the options causes the problem.

I'll mess with it and report back - thank you.  I downloaded v5.10.1 and the problem is there as well.  Outlook new message alerting works for a while but then stops.  Stopping/starting Taskbar corrects it again for another stretch.

I've had no luck isolating what is triggering the Outlook alerting to stop.  I've done multiple test scenarios in Taskbar and all end up the same after a period of time.  When Taskbar is stopped Outlook alerting resumes.   It continues to work for a while after being restarted before failing again.

This seems to have corrected itself with the latest Outlook Semi-Annual Enterprise update (v2102 build 13801.20808)

Thx!
