We have an issue where an outside Vendor sends an appointment they are sending to at least 7 other people.
Only one of them gets the appointment as an email, the other get it as an appointment.
I reset Client Options, Ran GWCheck (all OK), Moved to another Post Office, still get email not an appointment.
user has GW12.0.2 All Post Offices, Domains, MTA's etc is 12.0.2
Searched for TIDS, still stuck.
Any suggestions to figure out what is happening?
