Microsoft Fixes Outlook Bug Blocking Access to Encrypted Emails

Microsoft has fixed a bug affecting Microsoft 365 customers using the classic version of Outlook, which prevented access to encrypted emails following a recent update. The issue specifically impacted messages protected by encryption, though no details were provided regarding the protocols or standards involved (e.g., S/MIME, Office 365 Message Encryption). Neither the exact date of the fix nor the affected version number was disclosed. The impact was limited to the inability to open these emails, with no mention of data leaks or encryption bypass.
