Microsoft is investigating a known issue that affects Microsoft 365 customers and causes classic Outlook to hang or freeze when copying text.

Microsoft has announced new cybersecurity enhancements for Outlook personal email accounts as part of its 'Secure Future Initiative,' including the deprecation of basic authentication (username + password) by September 16, 2024.

Microsoft warned Outlook for Microsoft 365 users that clients might have issues connecting to email servers via Exchange ActiveSync after a January update.
