dynamically share a resource mailbox (calendar) between two organisations
Is it possible to dynamically share a resource mailbox (calendar) between two O365 organisations (domain) like a normal mailbox?
- It's the "Default" permission entry that is used, just make sure that it is set to LimitedDetails (well, anything other than None should do).
Again, there is no need to "share" the calendar if you have an org relationship in place, the Default ("standard"?) permissions already allow people on the other side of the org relationship to view it.
If you do want to share it for some reason, you need to add it to Outlook as additional account. To do that, you need Full Access permissions granted. Then follow the steps here: https://www.michev.info/Blog/Post/2025/how-to-add-a-shared-mailbox-as-additional-account-in-outlook-2016-build-8431-and-above-on-windows-10-1709-and-above

after some time of synchronization it works.
The rights for standard /Default were not good.
Can I remove the rights for anonymous?

- Yes, anonymous shouldn't matter.
