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 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?

    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.

    ... I tried your fix to revert to version 2035, even though Outlook 21 was not included in your list of versions, and it did not work ...

    Hi Pete James1:

    Do you mean that the instructions did not roll back your MS Office 2021 C2R to Version 2305 (Build 16501.20210), or do you mean that the roll back to Version 2305 did not solve your problem with the "Outlook Closed while you had items open. Reopen those items from your last session?" prompt?

    Instructions on how to roll back to a previous version of MS Office C2R are also posted in Diane Poremsky's article Uninstall Updates in Office 'Click to Run' on slipstick.com, which includes a link to the companion slipstick YouTube video Rollback to a Previous Version of Office

    Diane's instructions were last revised on 27-Sep-2021 and do not specifically mention MS Office 2021 as an applicable product but her 27-Feb-2023 comment #22106 below those instructions indicate they should also work for MS Office 2021 C2R.

    As Gregory-Assistance Needed and Drcard:)) both noted, if you are using a retail version of MS Office 2016 C2R or 2019 C2R (and presumably, MS Office 2021 C2R) then temporarily stopping your Office updates (File | Office Account | Update Options | Disable Updates) and entering the command "C:\Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.16501.20210 in an elevated command prompt with Administrator rights should should roll you back to the Version 2305 (Build 16501.20210) released on 13-Jun-2023. Previous version numbers and release dates for retail versions of MS Office 2021 C2R are posted <here>; for MS Office 2016 C2R and MS Office 2019 C2R see <here>.
