Quick answer: Set the device time and zone automatically, verify the Microsoft account or Outlook calendar zone, then fully restart Teams and compare one test meeting.
Teams meeting times can be wrong when the operating system, Teams account, Outlook mailbox, or browser uses a different time zone. Work through one test at a time so the result identifies the layer that is failing.
Why this happens
The best clue is the boundary of the problem: one file or every file, one device or several, one network or every network. Note when it began and any update, hardware change, permission prompt, or account alert that happened just before it.
- The device clock is correct but its time-zone label is wrong.
- Outlook on the web or the mailbox calendar uses a different zone.
- A browser profile or virtual desktop reports another location.
- The invitation was created with a fixed zone or daylight-saving offset.
Fix it in the safest order
- Record the meeting’s original zone and compare it in Teams, Outlook, and the web calendar.
- Enable automatic date, time, and time zone in the operating system and sync the clock.
- Check calendar time-zone settings in Outlook or Microsoft 365.
- Sign out of Teams, quit it fully, and reopen after settings synchronize.
- Create a private test meeting one hour ahead and compare every device before editing real meetings.
Repeat the same small test after each change. Keep a note of the original setting so you can restore it if the change does not help.
How to confirm the fix
The test meeting should show the same local clock time and explicit zone in Teams, Outlook, and the recipient view.
Common mistakes to avoid
- Do not manually change the clock to compensate for a time-zone error.
- Do not reschedule a real meeting before checking the invitation zone.
- Do not assume every participant sees the organizer’s local zone.
FAQ
Why is the meeting correct on my phone but wrong on my PC?
The two devices or apps probably use different time-zone settings or one has not synchronized the mailbox change.
Should I reset or reinstall everything?
No. A factory reset destroys useful evidence and is rarely the first step. Back up important data, test a second file, account, network, or device, and use the narrowest reset that matches the confirmed cause.
