I've got a headscratch of a problem with Outlook classic: users on Exchange Online can't see calendar items belonging to our on-premise users, even though they can access the calendars themselves. It works fine with OWA and Teams, so I don't think the hybrid setup is at fault. Interestingly, the new Outlook seems to be functioning properly. I even tried creating a new Outlook profile, but that didn't help either. Any suggestions on how to fix this?

Are both users using the same license level in Office 365? Sometimes discrepancies in licensing can lead to these visibility issues.
It’s usually the legacy Outlook app that messes things up when the web versions work seamlessly. There might be some odd settings or a pesky cache issue causing this, and a fresh profile often doesn’t fix it completely.
I get that! I already tried a new Outlook profile, but I didn't create a new Windows profile. We are also waiting for a new signature solution before we move to the new Outlook, which is causing delays.
Have you tried installing the new hybrid application? It's essential for rich coexistence between on-prem and online systems. It's not mandatory yet, but it's worth checking out if you haven't done it yet!
Yeah, I installed it. Some users reported it fixed their issues, but I just got a new ticket with another user facing the same problem. Ugh!
Yes, they are both on the E3 plan.
