Outlook 2016
Zarafa 7.1.2 server
Zarafa 7.1.14 52068 client
When trying to schedule and appt in every machine that has 2016 the appts show up as grey for the schedule, when I move the mouse of the grey it says "We're checking everyones calendars", it never updates.
I have tried going back a few versions with the same errors. Any help is appreciated.
