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 just downloaded the latest version 8/8/23 and it's working fine

    Hi jimjacksonxd:

    I don't see anything in the release notes for Version 2307 / Build 16626.20170 at https://learn.microsoft.com/en-us/officeupdates/current-channel#version-2307-august-08 that would indicate a bug fix was included in the 08-Aug-2023 update. Do you mean you no longer see the “Outlook closed while you had items open. Reopen those items from your last session?” prompts at Outlook startup? I haven't applied any of the workarounds suggested in this thread and my “Outlook closed while you had items open...." prompts can disappear for a few days and then mysteriously re-appear again, so be sure to post back if you see another one of these prompts in the next few days.

    I personally won't consider this bug fixed until the dropdown box that controls the appearance of this annoying prompt actually reappears in my settings at File | Options | General | Start Up Options .

    EDIT:

    Sorry, I just saw your post <here> on page 11 of this thread confirming that Version 2307 / Build 16626.20170 did not fix your problem.

    Dell Inspiron 5584 * 64-bit Win 10 Pro v22H2 build 19045.3208 * Firefox v116.0.2 * Microsoft Defender v4.18.23070.1004-1.1.23070.1005 * Malwarebytes Premium v4.5.34.275-1.0.2102 * Macrium Reflect Free v8.0.7279 * Microsoft Office 2019 Home and Business 2019 Version 2307 / Build 16626.20134 Click-to-Run

    Well you can disregard my last post. It's back again. Microsoft is a waste!

    I found opening outlook in different modes cleared the error.

    Its not as academic as registry keys changes etc and probably similar to tapping it with a hammer.

    1st open with the restore switch: Windows Key + R and in the dialogue box type, "Outlook /restore" (obviously without the "").

    Then close the program.

    2nd, open in Safe mode: Windows key + R and in the dialogue box type, "outlook /safe" (obviously without the "").

    Then close the program and open in normal mode with the normal shortcut/icon.

    It is OK so far, I have only tested it (by opening and closing the program many times for 30 mins), so I am crossing fingers.

    FYI: To open Outlook or any Office app in safe mode: hold down the Shift key while clicking the shortcut to open the app. A box will open asking you if you want to start that app in safe mode. Quick and easy.
