Microsoft has addressed a bug that prevented Microsoft 365 customers from accessing encrypted emails in classic Outlook after a December update. Users attempting to open messages encrypted with 'Encrypt Only' permissions encountered issues, seeing a message_v2.rpmsg attachment instead of the email content. The problem was linked to the Current Channel Version 2511 (Build 19426.20218).
