Hi,

I manage two exchange servers in two separate domains \ forests. Domain A works great. Domain B sends and receives fine but OOF messages are not being delivered either internally nor externally.

I have confirmed OOF is correctly enabled on both servers.

[PS] C:\>Get-RemoteDomain | fl AllowedOOFType, AutoReplyEnabled, AutoForwardEnabled

AllowedOOFType     : ExternalLegacy
AutoReplyEnabled   : True
AutoForwardEnabled : True

When I run a MessgaeTrackingLog query on both servers specifically looking at a senders message log and isolating the message subject which is prefixed with "Automatic Reply:" the logs are vastly different.

The working server in Domain A has usually between 10 and 11 steps for processing messages prefixed with "Automatic Reply" but the dysfunctional domain B only ever has 2 steps for messages prefixed with "Automatic Reply"!?!?

Below is the working Exchange server in Domain A - DomainA-EX01 log data...

Timestamp	    ClientHostname	                EventId	         Source	        TotalBytes   Sender	                   Recipients

2015/08/14 16:44    DomainA-EX01.domain.local	        RECEIVE	         SMTP	        9016	          user@domainA.com	   abc@xyz.com
2015/08/14 16:44		                        TRANSFER	 ROUTING	8189	          user@domainA.com	   abc@xyz.com
2015/08/14 16:44    DomainA-EX01	                AGENTINFO	 AGENT	        11937	          user@domainA.com	   abc@xyz.com
2015/08/14 16:44    DomainA-EX01	                SEND	         SMTP	        8500	          user@domainA.com	   abc@xyz.com

Below is the server not sending OOF messages in Domain B - DomainB-EX01 log data...

Timestamp	    ClientHostname	        EventId	         Source	        TotalBytes   Sender	                Recipients
2015/08/14 13:26		                RECEIVE	         MAILBOXRULE	5042	          user@domainB.com qre@lfd.com
2015/08/14 13:26		                RECEIVE	         MAILBOXRULE	5054	          user@domainB.com qre@lfd.com

Note the vast difference is the EventId and Source transactions of log data. Can somebody please talk me through these steps and explain why they are missing on the dysfunctional exchange server?

Both servers also sit behind the same firewall and no MTA is working on the firewall \ proxy so I am ruling that out.

Thanks in advance...

Hi Durrie,

Hope you are on Exchange 2013 only. Do you see more if you remove 'Automatic Reply:'

Hi Satyajit,

Both boxes are V15...not sure what you mean by 'see more'...?

Hi,

First of all, make sure message tracking is enabled on mailbox server in domain B.

And you said you send a mail from my hotmail account into the organisation with no OOF reply receiving, so if users on domain B can send messages to external? Internal OOF is working as expected?

Since the only difference between dysfunctional and working exchange box is patch levels with 'Important Updates', how about removing the KB3040856 - Security Update from dysfunctional exchange box to take a test.

Best Regards.
