Enable Receive Connector Protocol Logging on Exchange 2007

Standard Exchange Message Tracking from EMC Toolbox is a useful tool and often helps to diagnose message delivery issues. However if message is rejected at Hub Transport level it will not be logged in Message Tracking logs. To trace such messages you need to enable Receive Connector Logging.

Open Exchange Management Console > Server Configuration > Hub Transport > [Receive Connector] > Properties > General > Protocol Logging Level
Change the level from None to Verbose.

By default logs will be saved in :

C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive

Make sure you disable logging after troubleshooting is finished.

If you have Edge Transport Server you will need to enable Protocol Logging on Edge Transport Receive Connector as this will be the first place where messages hit your network.

    GroupName - Name (not Display Name) of the group
    UserName - Domain logon of the user who will have Send As permission.

  5. Repeat step 4 for all required users.
  6. Wait for Exchange/Domain replication to propagate permissions. Can take up to 2 hours.
  7. If you can't wait 2 hours try following
    • Restart Microsoft Exchange Information Store service on the Exchange Server. All users will be temporary disconnected and Outlook users may need to restart the Outlook to reconnect.
    • Update offline address book:
        • On Exchange Server: Exchange Management Console > Organization Configuration > Mailbox > Olline Address Book > [address book name] > update

Exchange 2007 - Allow user to access other user's mailbox and send-as...

You can give admin1 full access to user1 mailbox and allow him to send emails as user1. user1 can be shared mailbox such as Sales, Support, etc.

You can do this either in Exchange Management Console (EMC) or Exchange Management Shell (EMS)

Option 1: EMC

  1. EMC > Recipient Configuration > Mailbox [use1] > Right Click > Manage Send As Permission > Add.
    Find admin1 > OK > Manage
  2. EMC > Recipient Configuration > Mailbox [user1] > Right Click > Manage Full Access Permission > Add.
    Find admin1 > OK > Manage

Option 2: EMS

  1. Add-MailboxPermission -identity user1 -User admin1 -AccessRights FullAccess

  2. Add-ADPermission "User1 Name" -User admin1 -AccessRights extendedright -ExtendedRights "send as"
    "User1 Name" - full object's name (or distinguished name), not alias.

After steps in either option are performed admin1 should immediately have access to user1 mailbox, however Send-As permission may not kick in for an hour or two.

Exchange rejects external emails to distribution group

Created a new distribution group on Exchange 2007 or SBS 2008. Internal emails are delivered, but external rejected with bounce "550 System error".


Problem may be caused by "Require that all senders are authenticated" option in distribution group properties.
Exchange Management Console (EMC) > Recipient Configuration > Distribution Group > [name] > Properties > Mail Flow Settings > Message Delivery Restrictions - Require that all senders are authenticated
If you want to receive external emails this option must be unchecked.



The same option could also prevent external email delivery to user mailboxes and other exchange objects.
