Email delay between two sites

I would query the queue while its holding the message to see the status, as this would give us a better idea on how to figure this out...

Get-Queue <queue in question goes here> | Get-Message | FL 

Select allOpen in new window

Furthermore try the following within the command prompt..

From one Exchange multi-role server run the following:

telnet fqdn.of.other.exchange 25
EHLO

What is your output from the EHLO request (do you see the exchange X-Verbs) and what is the first banner? You can take two screen shots of this also that would be awesome.

its very difficult to get queue. sometimes i log in to server , queue already cleared :(

Do you know if there is an error  when the messages are in queue?

+1 Adam.

When the error occurs, check the Queue Viewer, see what is reported in the Last Error column.

hi adam,

I get below error on Queue.

""451.4.4.0 Primary target IP address
responded with 454.4.7.0 Temporary Authentication failure. " Attempted
failover at alternate host, but that did not succeed. Either there no alternate
hosts, or delivery failed to all alternate hosts"

Exchange Servers are running on Vmware.

I assume this has never worked then?

This sounds like a permissions issue on the Receive Connectors. How are your receive connectors configured? What are the settings under Permission Groups?

If it has worked before, were any new receive connector recently created?

Not this happen only for 10 min, next 5 min email will be back to normal.

@UCGuy,

Please run the following on a HUB transport server in each site:

Get-ReceiveConnector | FL

Throw them into a text file and upload them if you can.

I had to disable the time sync on VMware tools.
