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.

    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.

    My contact in support just let me know that he repro'd it in both Outlook 2019 and 2021 and submitted a bug report on it.

    I recommend restarting Outlook once a day (if you are a never close, never reboot type) as they can push out silent updates overnight to fix bugs but the updates are not installed until Outlook is restarted.

    Thanks for the reply and info. I reboot my machine every other day or so, and it's always either in "sleep" mode or powered down at night. Thanks for your persistence! Much appreciated.
