How to stop outlook from opening a browser every time I create a meeting?

Hunter,

We did not document this issue that started on 6/7/23. I checked the In App tickets today and all of the tickets we had for this issue the customers said the issue is now resolved. If this had been a long running issue, I would have reactivated this Known Issue and appended it there for easy discoverability, https://support.microsoft.com/en-us/office/outlook-unexpectedly-opens-a-browser-window-if-owa-is-disabled-4c915e88-0654-4f77-8daa-a624600dc718. One main thing to mention is that this issue occurred even if the OWA protocol was enabled.

Is there a public record of this bug anywhere that can be linked to and checked for updates?

Thank you, Chris. The Outlook In App Team has a bug submitted for this issue. I was checking to see if that bug should be appearing in production, and it appears it does because I see numerous tickets now for production users. Per updates in the bug the OWA team has implemented a fix and it is rolling out to the internal rings now. I'll post back when I know the fix will get to production.

Can confirm all four email accounts look identical to below: All four are exchange, three are 'Microsoft 365 Business Basic' and fourth account is Microsoft 365 Business Standard.

Since this post I have opened a ticket actually. So you might see mine.
