    We are seeing the same problem, even with synching between personal calendars on Outlook.com and our MS365 tenant - inconsistent and lengthy delays between synchronization.  If instant synch is not working properly even between two Microsoft-controlled calendars, that's frustrating. 

     

    The very slow and inconsistent refresh rate then causes problems when using Microsoft Bookings, which should be respecting free/busy information from a linked Outlook.com personal calendar.  Multiple hours between synchronization makes this impractical.  Please offer a solution, if anyone has it!

      I do have the same Issue here, it's really annoying as cross-organization calendar sharing shouldn't be something to worry about nowadays. We often work with external partners / clients where calendar sharing makes life so much easier!

        Today (4th November 2021) I am still facing this issue. Sync is so unbelievable slow between two Microsoft 365 tenants with an organization relationship between. Within each of the organizations, it works flawless but across is quite a pain in the **bleep**. I am starting the have a difficulty explaining this to the users... please fit it.
