Re: Email Dates in Inbox of Mac mail in Office365 showing incorrectly.

Hi praga,

I tested it in OWA, setting the current time zone to (UTC-06:00) Central Time (US & Canada) and (UTC-07:00) Arizona. The displayed email dates are different which show separately below.

Therefore, could you check if the time zone setting is correct? To change the time zone, please follow the steps:
Go to OWA, click Settings -> Options -> settings -> regional -> select your time zone in the drop-down list of Current time zone -> click save.
