Anyone noticed if you're running Outlook on Server 2019 or 2022, there is an option in Calendar to change the time zone - and if a user uses it, it changes it for the entire system? I used Ivanti to block the menu control as I can't find a GP to do it, and if you do that, it blocks them from opening attachments 😞 Don't suppose anyone has worked out how to block this (sounds like a bug TBH)? Removing rights from everyone to "change the system time" (including admins) makes no difference....
