This just started happening. Whenever I open Outlook, I get the message "Outlook closed while you had items open. Reopen items from last session?" even though this is not true -- I did not have items open when I closed Outlook. Using Windows 11. Screenshot of what version of Outlook I have:

Outlook | Windows | Classic Outlook for Windows | For business

I'm on build 2306. Is this the reg key in question?

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences
DWORD: ReopenWindowsOption
Value: 1

Yes.

Some users that updated to 2306 have reported that the key was not already in the Registry and had to add it and the value.

    Hi Fab2016,

    I'm not at all sure about the process for the Outlook icon, as I didn't change anything to do with the icon.

    Pleased to hear that many people are getting back to normaility.

    Pete

    Hi all,

    The fix was ported to the latest Version. The build with the fix just became available. It's not being pushed yet, so you will need to update manually by clicking File, Office Account, Update Options, Update Now. Sometimes not everyone can get the build when it first comes out but worth checking if you can.

    It will show as Version 2309 Build 16827.20130:

    I also updated the Known Issue with this fix status, Outlook unexpectedly prompts to reopen items from your last session - Microsoft Support.

    That is the exact same behavior as my client.

    My contacts are all in the US and were off for the Independence day holiday yesterday so it might be a few days before I hear back from them.
