We use Office 365 (current channel) and are migrating users to Exchange Online. One of test user ran this search in Outlook.

Received: 06/25/2021

The result is that we get results from 6:00 pm the day before to 6:00 pm of that day. It appears that Outlook is not adjusting for our TimeZone which is currently Mountain Standard Time.

When I check Exchange Online, everything appears correct:
<user> en-CA yyyy-MM-dd h:mm tt Mountain Standard Time

When I check their PC everything appears correct.

What am I missing?

    Hi @Daniel Kaliel

    According to my test, O365 search uses UTC time. For example, in my timezone (UTC+8), If I search the messages received on a specific date, I would get result from 8AM to the next day's 8AM. This seems to be by design and cannot be changed. Even if we have changed all the timezone for our account.
