(On Premise 8.3)
I have a single user that has the alarms windows popping up all the time. If I remove the applointment from Outlook and wait for sync, the next appointment will do the same.
Has anyone seen this behaviour?
I had a closer look at the Win code that is responsible for invoking the alarm.It hasn't changed much for many years and I did not find a potential candidate.Since you seem to indicate that Outlook Mail Link or Synchronizer is involved and the problem persists, you need to register a support case.
