Whenever I schedule a meeting, Teams warns me that some attendees are in a different time zone. Except they aren’t. I’ve confirmed with coworkers and checking our settings.
And then there’s the “helpful” way teams resets the calendar view: let’s say I’m going back through calls from last week to see how long they took. In Teams, I go back a week, click the calendar item, record the time in my app, then go back to the calendar view and…I’m on this week. Neat. Intuitive.
I used to have a problem very similar to this, where the "working hours" Teams showed on my profile were in the wrong time zone. It turned out the solution was to go deep into some submenu of the Microsoft account settings website (_not_ anywhere in the actual Teams app) and edit the account time zone preferences, so perhaps look into that and make sure those match the local settings in the Teams app.
I appreciate it but at this point I’ve given up on it. It doesn’t cause any issues, or hasn’t thus far, outside of the annoying nag. That said, if I ever get to digging in again I’ll check in to those settings - thanks!
