Hello World,
Got this strange issue. A user sent an email to two users and once sent she clicked reply all. The others users have not replied back to her all however in the reply all draft email it added a random internal email address of someone else who was not part the original email sent.
User is adamant that she did not BCC the person nor has she ever contacted that person. In fact just to bcc someone in outlook she would have to actively enable that option. Whats strange is that she gets this error only in this email, all other emails are working fine and do not have this error. In the end she clicked reply all and removed the random email address.
Checked rules and there are no rules in place.
Any advice would be appreciated. Cheers
