I work with individuals from another organization that use Microsoft 365/Exchange for their email and calendaring services. I tried adding a calendar they shared with me in my UMD Gmail, but I'm not seeing timely updates of calendar changes. I'd like to view real time updates of the calendar they shared with me. 

UMD email.

To view real-time updates of the shared Microsoft 365 calendar, you will need to add the calendar to the desktop version of Microsoft Outlook. 

Install Microsoft 365 applications on your computer

Install the latest version of Microsoft Office (which includes Outlook) from TERPware.

Have the individual share their Microsoft 365 calendar with you

The individual whose calendar you wish to view will need to share their calendar with you first. Please see Microsoft's Share an Outlook calendar with other people article for instructions sharing Microsoft 365 calendars. Once the calendar is shared with you, you will receive an email invitation with a link to Accept the calendar.

1. Open the email with the shared calendar and select Accept in Microsoft Outlook.
2. Select Calendar and then Shared Calendars to view the shared calendar.
