In order for the time of an appointment or meeting invitation to be reflected properly, settings in Windows and in Outlook must be correct and they must match. There is no reason to suspect that our servers have the wrong time settings since meetings and appointments time is always local to your mail client.

In Windows/Outlook:

    1. Open Windows Control Panel and double-click Date and Time to open it.
    2. In the Time Zone tab or section, make sure that the time zone and Daylight Savings Time settings are correct for your region.
    3. In Outlook 2010/2013 go to File > Options > Calendar. Click the Time Zone button. Verify that the time zone and "Adjust for Daylight Savings Time" settings are correct and that they are the same as the settings in the Windows Date and Time control panel.

In Outlook Web Access:

Click Options and find the Date and Time Formats section, or the Regional Settings section. Verify the settings for Current time zone.

In MacOS/Outlook 2011 for Mac:

Click on the system time. Open Date and Time > Time Zone. Adjust the time if necessary (this requires administrative access).
