While using the Outlook App on Windows 10, Creating a new event in Calendar, and ONLY when selecting Invite Attendees button, Outlook will open a tab in my browser that does nothing but have the outlook logo.

    Greetings All,

    Had the same issue. Disable "Continue running background extensions and apps when Microsoft Edge is closed" and your problem should go away.

    Outlook Unexpectedly Opens a Browser Window if OWA is Disabled

    At least Microsoft is finally acknowledging it.  However, a fix isn't expected until mid April 2023 at the earliest, according to the article linked above.

    As of build Microsoft® Outlook® for Microsoft 365 MSO (Version 2211 Build 16.0.15831.20098) 64-bit this issue no longer affects the calendar selection... Now every time we open the outlook desktop app, it launches the web version. This is happening immediately the Outlook Desktop app is opened.

    Microsoft told me this is a bug in the current O365 release and should be fixed in the next patch.

    As a workaround, they gave me a registry key to deploy and it has worked for all users that have received it. I did not have to make the users enable the Microsoft exchange add-in as it was already enabled in our environment by default.

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Options\CalendarAdd: ShowLegacyRoomFinder with dword value 1

    Here is the PowerShell script i used for deployment in case anyone needs it:

    Set variables to indicate value and key to set

    $RegistryPath = 'HKCU:\Software\Microsoft\Office\16.0\Outlook\Options\Calendar'

    $Name = 'ShowLegacyRoomFinder'

    $Value = '1'

    Create the key if it does not exist

    If (-NOT (Test-Path $RegistryPath)) {

    New-Item -Path $RegistryPath -Force | Out-Null

    }

    Now set the value

    New-ItemProperty -Path $RegistryPath -Name $Name -Value $Value -PropertyType DWORD -Force

    You can deployed it via GPO as well

    Here is the article with details.

    Thanks! Everything I'm finding points to it being a known issue, and it appears to only happen to organizations who have OWA disabled. Hopefully a fix goes out soon for this.
