In Outlook desktop, go to File → Options → Calendar → Time zones. Select your time zone from the dropdown. In Outlook on the web, go to Settings → View all Outlook settings → Calendar → View and set your time zone. Both methods update all calendar event displays and the default timezone for new events.

Can Outlook display two time zones at once?

Yes. In Outlook desktop, go to File → Options → Calendar → Time zones and check the “Show a second time zone” box, then select the second zone. Both time zone columns appear in your calendar day and week views. Outlook on the web also supports this in Calendar settings.

How do Outlook meeting invites show time to recipients in different time zones?

Outlook automatically converts meeting times to each recipient’s configured local time zone when they receive the invite. The email version of the invite also includes the organizer’s local time and UTC offset so recipients can verify. This works reliably when both sides use Outlook with properly configured time zones.
