Viewing Guests' Availabilities (Google and Exchange Users) in a Calendar Event
We can check calendar availability between SBU Google and SBM Outlook accounts.
- June 04, 2026
We are currently experiencing a performance issue with the synchronization of calendars between the Stony Brook University Gmail and Stony Brook Medicine Outlook email systems.
As a result of this issue, some Stony Brook Medicine users may encounter inconsistencies when viewing Stony Brook University Gmail users' availabilities and events.
Google Calendar
For Google Calendar users
- Add guests' Stony Brook email addresses
- For Stony Brook Medicine users, you must use their @stonybrookmedicine.edu email addresses (using Stony Brook Medicine users' @stonybrook.edu email addresses will not work but will indicate that the calendar can't be displayed by an *)
- Google Calendar users may see up to 62 days into the future when using the Find a Time or Meet With functions.
- Click Find a Time, and if you have access to view their free/busy time, their free/busy times will display
- If guests' names have * after them, their calendar can't be displayed (because you may not have permission to the indicated calendars or the guests may not use a supported calendar)
Microsoft Outlook (Exchange)
For Microsoft Outlook (Exchange) users
(the way you access Scheduling and how it looks might be slightly different depending on your version of Outlook)
- Add guests' Stony Brook email addresses (@stonybrookmedicine.edu or @stonybrook.edu)
- Click Scheduling, and if you have access to their free/busy time, their availabilities will display
- If
displays for guests, their free/busy information is not available.
