Not Seeing your “Other Calendars” from Office 365 in GReminders? Here is the fix

If you are an Office 365 Outlook Calendar user and do not see your other Calendars here is what you need to do.

Missing Calendars Here

Normally you would go to MANAGE CALENDARS where you manage/add Calendars GReminders has access to:

Perhaps you are expecting to see more calendars that you should have access to.

There could be a couple of things going on.

Group Calendars

If your Shared Calendar is a “Group Calendar”, please click on the Group Calendar link:

and authorize Group Calendars.

Shared Calendars from your Directory

Another thing you can try is adding a Calendar from your Directory.

Login from your Web Browser to your Office 365 Outlook Calendar. Do this from Microsoft Edge Browser (on Windows) or Safari (on Mac). Go to and login, then navigate to Outlook and then the Calendar. You should end up at a web address that looks like this:

From here, go to Add Calendar and Add from the Directory of Calendars, find the Room/Shared Calendars and add them, like so:

Add from Directory

Afterward, in Outlook you should see them in “Other Calendars” like so:

Other Calendars

When you go back to the GReminders Manage Calendar screen you should now see the extra Calendar(s) like so:

Added Calendar

From here you can add them to your Calendars for Reminders or Availability and use them like normal.

Still not Working?

Make sure the User’s calendar that you have access to you can View All Details OR Can Edit. The User who owns the calendar should specifically share the calendar with you. On THEIR Outlook Calendar they should:

Sharing and Permissions

Then grant you (in this case Michael Scott) access to your calendar:

Edit details

Often times the RECEIVING user needs to ACCEPT the calendar invitation. Go to the Outlook Email and check if this calendar share request was received and accept it.

We recommend going to your WEB version of Outlook and doing this from there. and go to Outlook from there.

IF you are logged in as multiple users to your Office 365 account, we further suggest using INCOGNITO or PRIVATE browser mode to log into the user who is accepting the invitation. Microsoft often times gets confused as to which account is accepting the invite, thus we recommend Incognito or Private Browsing mode.

After all that, go Back to GReminders Manager Calendar screen and with any luck you should see the Calendar.

Still not Working?

In the screen above, REMOVE the share, wait 30 seconds, and RE-ADD the share. Sometimes it takes Microsoft a few minutes for this all to sync properly, and removing and adding of the share is necessary.

Note: If you do not have full permissions (or read only access) to these calendars, writeback and public scheduling or rescheduling may not be possible. But Reminders and Followup notifications should work just as normal.

If you still have problems or issues please contact [email protected]

Happy Scheduling!
