Microsoft acknowledged a bug causing classic Outlook to crash on startup (including Safe Mode) for Microsoft 365 accounts after Version 2407 Build 17830.20138+, tied to corrupted mailbox rules, and provided a workaround: run Outlook.exe /cleanrules, optionally create a new profile, and remove remaining rules via Outlook Web Access; it also noted separate recent issues affecting Microsoft 365 apps (Gmail sign-in and spell-check crashes) that received temporary fixes.
