Hello
I did it again and at the end I get this error message: It does not work.
I only want that the calendar in MS Teams works. The mailboxes should remain on Exchange. What else do I need to do here?
I must remember that we use Kemp Loadmaster. The OWA is running through Kemp.
thx

What did you end up having to do to fix your issues? I'm currently running into the same thing trying to get hybrid deployed. We want to keep mailboxes on-prem but I have also used entra connect to move identities to the cloud.
I opened up a support ticket with Microsoft as well but I'm waiting to hear back - just scouring the internet for more possible fixes.
Thanks!

Hello @Thameur-BOURBITA
unfortunately the page doesn't help me. It talks about Exchange Modern Hybrid Topology Modern, but in my case it is Exchange Classic Hybrid Topology.
The mailboxes are not migrated to Exchange Online, they all remain on Exchange 2019. It's only about the Classic Classic Hybrid.
thx

I've tried searching a lot and there seem to be very few similar cases.
Have you considered opening a support ticket to further resolve your issue?
