  • Hello!

    May be this trigger behaviour from Mailbox Audit Logging will help you, but I'm not sure now.

    Item's properties are updated.


    So for test - you have to turn on the Mailbox Audit for mailbox B, turn it on for -AuditOwner with Update item included.

    And then use Search-MailboxAudit -showdetails cmdlet for mailbox B.

  • Internet MessageId https://docs.microsoft.com/en-us/exchange/client-developer/web-service-reference/internetmessageid would be the Message property to use. You can use that to search with in EWS and also you can use it in Message Tracking which is a better way to work if a user actually received a particular Message you can then use EWS to see if was moved or deleted.
