Received Emails Should not Have Received

Hi Folks,

I am IT Manager for company of approx. 60 employees. Our email system is MS Hosted Exchange as part of our Office 365 subscription.

Yesterday, a very odd thing happened with 2 of 10 emails that my boss forwarded to an outside individual. For some unknown reason, I received 2 of the 10 emails that he sent, and  neither email was addressed to me.

I logged into Exchange Admin\Mail Flow\Message Trace and ran a report of email sent by my boss during the time-frame in question. Please see below.
Message Trace from Exchange
Emails #1 and #2 are the same email, sent to just Geoffrey, but, also received by me, shood.  I should not have gotten this email.

Email # 3 also sent to just Geoffrey, and NOT received by me, as should be the case

**NOTE** Word "Expanded" is a status for the two emails that went to more than intended recipient.

I cannot find a reason for this, there are no forwarding rules in place. My bosses sent items do not show me as being a recipient for any of these emails.

Any ideas?

Any chance the sender used BCC  to copy others?

The sender sent the email and then deleted the sent mail because they made an error?

Too much of a coincidence for Exchange to do this.

No, we chatted on this, he did not BCC me or anyone else. Exchange caused this just don't understand how or why.

I have not seen Exchange do anything like this.

Perhaps delete and recreate the user's Outlook Profile. Go to Control Panel, Mail, delete the Profile, restart the computer, and set up a new Outlook Profile (again in Control Panel, Mail).

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

expanded generally denotes it could have been a distribution group, so maybe he sent it to a distro and you are in that distro or there may be a forward on the recipient mailbox that caused it to forward to you. have you checked that this wasn't sent to a distro or their was no forwards on the recipients mailboxes
