Microsoft has resolved a known issue that caused Outlook Desktop to unexpectedly prompt users to reopen previously closed windows.
On affected systems, users of Outlook for Microsoft 365 were encountering dialogs with prompts like "Outlook closed while you had items open. Reopen those items from your last session?".
The option to automatically restore Outlook windows, enabled by default, was rolled out to Microsoft 365 subscribers using Outlook for Windows on Beta Channel Version 2006 in June 2020.
"Whether Outlook closed due to a crash, a system update, or when you explicitly closed it, you'll now be asked if you want to reopen any windows that were previously open," Microsoft describes the feature in a Microsoft 365 Insider communication.
The Outlook Team has also introduced interim solutions to address problems after installing July's Microsoft Office security updates.
