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.

    I’ve tried every fix on the internet. Nothing works. It goes away sometimes but always comes back with new last open windows. Sometimes a reboot works. But then comes back. Also there is no available setting for startup switch in outlook 2019. Thanks

    I updated to the latest build, it worked for a while and then the dialog box "Outlook Closed while Items Open..." reappeared persistently again. I don't have an elegant fix to something MS could do easily. As I posted a couple of weeks back, if you edit the Target field in the Outlook desktop icon to add the switch /restore as follows ["..../outlook.exe" /restore] it stops the dialog box aggravation but does of course open any items that were actually open the last time.

    I also get the annoying pop up most times I open Outlook

    I do not have a "Start up option " to chose. Blank. No "Ask me if I want to reopen previous items."

    Also, periodically it does not open when picked, like it locked up closing a session.

    I'm pretty happy with the Michael Mead1 suggestion ( thanks, Michael ) about adding /restore to the Outlook icon.

    I suggest it to everybody suffering for that annoying message.

    BTW, I judge closing all open emails before closing Outlook to be a good practice.

    It is my habit to do that, since ages ago.

    Outlook 2019 Professional Plus, ver. 2307.
