There is a problem with the Outlook web meeting time

Hi, @Cranbin

With your description, I would like to confirm your question further.

1. Do you mean that the new meeting will not be displayed immediately, but will be displayed in OWA's calendar after one hour, or is it one hour different from the meeting start time of different people (e.g., user A has booked a meeting at 10 o'clock, and user B's calendar shows that the meeting start time is 11 o'clock)?
2. Do all meetings created in OWA have the same issue?
3. Do all attendees of the meeting have the same problem?
4. Does the issue exist in an internal or external meeting?
5. Are the participants in the same time zone?

The general reason for this issue to occur is due to a time zone issue in OWA. Outlook desktop client uses the time zone of the host operating system, and if both of your client computers are configured with the same time zone, the meeting will appear on both computers in Outlook at the same time. OWA cannot assume that the client computer running the web browser is in the same time zone as the server, so OWA provides a user-configurable option where the user can set their current time zone, and this information is stored for each user, so affected users may need to make modifications to get the synchronization.

A common way to solve this problem is to modify the time zone in OWA.
