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 Again Great White North,

    You may see in the replies that I used the method as posted by Drcard:)) and it has worked for me.

    Hi Drcard:))

    Thank you for the advice and very detailed instructions on rolling back Outlook to the previous version number 2305 build 16501.20210.

    I have tried your fix, and it has worked with my systems Office 21 Pro. I'm now on the 2305 version number build 16501.20210, and the drop-down box is back displaying as it has done with three options. I did get the pop-up box when I first opened Outlook again, but it settled after a re-start.

    I hope that others will give this a try, or Diane Pomersky's method as outlined by Great White North. If I can do it successfully you can!!

    Can someone with greater experience of these situations, explain why we haven't heard a peep from Microsoft, via their moderators. I'm certain that there is an expert team feverishly working on this glitch, and I'm thankful to them. I wonder if the Microsoft boffins/management would accept no feedback or progress updates from service providers that they deal with.

    Is this position a bit harsh?

    Pete

    Hello again Great White North,

    The instructions did not roll back the previous version. Perhaps I did something wrong.

    Thanks for the in-depth article you have sent, I will have a closer look at the suggestions when I get home from work.

    Thanks for the post.

    Pete.

    I just disabled the Cloud storage options (Store my Outlook settings in the cloud) along with running it as an elevated (run as Administrator) to make sure any setting is set / created and then closed and run as normal and has been working fine for 3 days so far.
