Why can't I make a booking in Matrix Booking with the Microsoft 365 integration?

Problem / Question

1. Why can't I make a booking in Matrix Booking with the Microsoft 365 integration?

2. I get a warning message telling me that the resource I’m trying to book in Matrix Booking is unavailable in Microsoft 365. What do I do?

3. Why aren’t my calendars synced?

Solution / Answer

As you’re trying to book a room (Microsoft 365 resource), you may come across the following warning message:

If you get this warning message, it means that the Matrix Booking and Microsoft 365 calendars for the resources aren’t aligned properly. This issue usually happens because there are historic bookings in the Microsoft 365 calendar before a sync has occurred.

You need to:

1. Check the Microsoft 365 resource’s calendar for any historic or future bookings.

2. Follow the steps in our Microsoft 365 integration setup guide .

3. Link all your Microsoft 365 resources in Matrix Booking (rooms only).

4. If you have any future bookings against any resources that you want linked, any existing future bookings between the two systems aren’t automatically synced. You may come across one of the following error messages when you try to link the resource:

   • Future bookings in Matrix Booking:

     

     
     

   • Future bookings in Microsoft 365:

     

     
     

   • Future bookings in both Matrix Booking and Microsoft 365:

     

      

5. Raise a support ticket to let us know:

6. If you’re using either Matrix Booking or Microsoft 365 as your “master” resource booking system where the future bookings currently reside.

   • The date you want the sync to happen.

   • The date range of bookings you want synced.

7. Our Support Team will run:

   • A future bookings analysis.

   • The future booking sync for you, so that they appear in both calendars.

8. You’ll need to finish the integration setup for any resource that doesn’t have any future bookings against it.
