We recently had a customer that was having a hard time updating his time zone for Exchange Online in Office 365. Here are the instructions on how to set this up.
1. Log into Outlook Web Access
2. At Top Right click on “Options”
4. Then choose “See All Options” which will take you to a different screen
5. On the left hand side click “Settings”
6. Then click the icon which says “Regional”
8. Then choose your time zone the drop down and save.
