Exchange Hybrid: Shared Calendar issues with Outlook
Since approx 48hrs ago we noticed Outlook not receiving new calendar updates / meetings from on-prem Teams rooms calendar mbox in a hybrid scenario. The Teams room calendar itself receives the invita...
That is actually incorrect: I have been using Teams with on-prem Exchange mboxes for years and it is a supported scenario since day 1 as the only way to use Teams with on prem Exchange is de facto a *hybrid* configuration whether basic (just oAuth) or full-blown and once this is setup it makes really no difference whether the mbox calendar is on-prem or in EXO (if it were, no on-prem individual nor shared mboxes' calendars would work).

The problem here is not really related to Exchange per se but rather the client Outlook 365 in cached mode after a recent update. Non 365 versions of Outlook continue to work correctly in cached mode.

oh you are not talking about Teams Rooms specifically, you are talking about a resource mailbox which u use as a teams calendar. I would suggest creating a ticket in your tenant, also if ur already in a hybrid mode why not just create a ad object on premise and the create the remote mailbox via powershell that way you won't have calendar issues.
this probably has to do with your inta organizational connector:

- Actually I was referring to a Teams Rooms - in any case I have resolved with the above workaround. It's highly probable that the issue will be fixed in Outlook 365 in future updates as I'm positive I'm not the only one with clients in this scenario.
