Hi,

I have an shared mailbox (Called Mailbox 01) which is receiving message which are sent to Mailbox 2.

I have check the forwarding settings on Mailbox 2 and I dont see anything which will be forwarding message to mailbox 1.

How do I track how these message are being delivery to mailbox 1 if they are not sent to mailbox 1 but they are sent to mailbox 2

From address is external and internal and TO address is mailbox 2 but for some reason its keep ending all of the message to mailbox 1

    Hi @lalajee
    First please check the inbox rules of mailbox2. You could use Get-InboxRule. get-inboxrule

    Check the mail flow rules again, is the recipient address correct? Do you redirect mail?

    Additionally, You could track messages in Exchange Online through EAC. With message trace, you can determine whether a targeted email message was received, rejected, deferred, or delivered by the service.trace-an-email-message
    You could also track messages in Exchange Online through PowerShell.
