Keep Getting "Outlook closed while you had items open. Reopen items from last session?" Even Though It's Not True

I am also using desktop outlook 2019. When Outlook opens It shows a message that it closed with items open. It appears that Options, general does not contain any settings under start-up settings.

This is most annoying please fix this issue asap.

Thanks Bill

I continue to have erratic problems with this goofy 'Reopen...' pop-up message, so I'm not about to further mess things up with finagling registry keys. As I say, too many times I've put my finger in the dike to stop the leak only to find that I've dislodged another pebble that in turn lets loose the small rock that's holding the bigger stone in and... voila, a full deluge.

I added that ' /restore' last week and since then erratic behavior. Last Saturday, Outlook started into a window with no problems (yay!) but then Sunday it remained minimized and I had to click on it again to get into a window. Monday it opened in a window, re-opened (again!) an already opened/read email from the previous day, AND gave me the "Reopen...?" pop-up. Tuesday it opened in a window, no pop-up, no previously read mail - all fine. Wednesday and this morning again it stayed minimized.

Every night before I close Outlook, I do a send/receive and make sure the little message "synchronizing all folders" at the bottom completes/closes. Then I close Outlook. I wait anywhere from 5-15 minutes (Solitaire helps pass the time) and then check Task Manager to make sure Outlook is not still running, then close down my laptop.

It is the peak of lunacy to do the exact same thing and get varying results, but there is a name that describes this - 'chaos', which in physics is defined as "behavior so unpredictable as to appear random, owing to great sensitivity to small changes in conditions".

There is something unstable down there in the coding of Outlook and dmmit, I wish they would fix it.

Restating my conditions of operation: Dell Inspiron 5501 11th Gen i5-11320H; Win 11 Home, v22H2, OS 22621.2134, Experience Pack 1000.22659.1000.0; Outlook 16.0.16626.20170; "Save my settings in cloud" unchecked, Missing Outlook "Startup Options" selections; added ' /restore' to Outlook icon; no registry key changes/deletions/additions.

This was never a problem until within the last two months (today is 8/18/23). Something caused this issue to arise, probably a Win update. The registry flag does not work for me nor does the trick of opening Outlook twice. I think the only solution will have to come from Microsoft, a coder must look into what triggers this message and what goes wrong to cause it to launch. Along with that, the coder's supervisor should look into what useful purpose the message popup serves in the first place. The simplest answer is for MS to simply delete the code that pops up the message and send out a patch to the zillions of people who have this problem.

Thank you for sharing a solution. Unfortunately, it does not work on my machine. Please see the below screenshots. Do you have any suggestions to resolve the issue on my machine?

Thank you.
