There is currently no route to the distribution group expansion server
You see the error “There is currently no route to the distribution group expansion server” in a stuck message from your Exchange Hub Transport server submission queue. To resolve this: Make note of the distribution group in the recipient information tab. Search for the Distribution Group in Exchange Management Console Right click on the group and choose properties Go to the Advanced tab Untick the box next to “Set expansion server” You might have to restart the Hub Transport or SMTP service depending on your Exchange version. We found this happened because the Expansion server was removed from the environment and not accessible. Another cause could also be the deletion…

Find a duplicate e-mail address in Active Directory
We recently started seeing a lot of mails stuck in the submission queues and found that there were a few duplicate e-mail addresses in the environment. Most of the time we could not find the duplicate addresses in Exchange and had to search for the duplicates in Active Directory as some addresses were bound to AD objects. To search for a duplicate address do the following: Open Active Directory Users and Computers Right click on your domain name and click on find Next to find choose custom search (see below screen shot) Then click on the Advanced tab (see below screen shot) Under “Enter LDAP query:” type the next search…

We’ve had a few instances where a user could not receive mail into their Exchange Online mailbox. Upon investigation we noted the onmicrosoft.com address is the primary SMTP address for the user and that the remote mailbox object is not available in Exchange on premises. To resolve this do the following: Open Active Directory Users and Computers (dsa,msc from start -> run) Click on View -> Advanced Features Do a search for the user who has the issue as per above Right click on the user and choose properties Click on Object and make a note of the path Close the search you made. Now navigate in Active Directory Users…

Messages awaiting directory lookup – Queue Build up on Exchange
We had an Exchange 2003 server that had a queue build up. The messages were building up in the “Messages awaiting directory lookup” queue. After investigation we found that the server had old DNS entries which were removed and new entries were added. The queue cleared almost immediately. If you see build up in the Messages awaiting directory lookup queue then be sure to check DNS is working as expected.

Exchange 2010 Queue Build up with Event ID 1035
We had an interesting issue with queues building up to remote sites. In queue viewer we noted errors sending mail to different remote sites as per below: 451 4.4.0 Primary Target IP Address responded with: “235 00000xxxxxxxxx” And in the Event Viewer we noticed event ID 1035 , MSExchangeTransport At first we thought the issue has to be on the specific Exchange 2010 server trying to send the mail as it was the only server in the DAG that could not send mail to the remote servers. However, the problem was still present after restarting the Hub Transport Service on the server experiencing the above issues. As a shot in…

Provisioning Layer initialization failed error when running a cmdlet in Exchange Management Shell
I’ve had the below error a few times this year when trying to open the Exchange Management Shell or running a cmdlet. To get this working browse to another Exchange 2010 server and copy the ScriptingAgentConfig.xml file from the working server and paste it in the same directory (as per below) on the non-working server. The file can be found under your Exchange Installation by default c:\Program Files\Microsoft\Exchange Server\V14\Bin\CmdletExtensionAgents\

Unable to Update a Storage Group copy and the event log shows – Event ID 2059, MSExchangeRepl
We had failed data base copies on a CCR cluster and running Update-StorageGroupCopy failed. The backups have not run for a while but I could verify that the logs were indeed present. The best way to get around this is to run an Exchange backup and the Update the Storage Group Copy. This was not possible as wee needed to urgently get the database copies healthy. We then had to dismount all the databases, checked that they are in a clean shut down state using eseutil.exe /mh and move the logs to a different folder. We then mounted the databases and were then able to seed the database copies.

Yes I know. The title for this post is extremely long but thought that it would be easier to find if it’s more descriptive. In any case. We had to rebuild a multi role server and the Hub Transport role was also installed. After the install we checked that all is good and I found that mail were queued up on the server. Further investigation showed that the Hub Transport service was not started so I tried to start it, which failed. The event logs showed the below error. I then checked the permissions of the trn.chk file and the queue folder and found that it did not match the…
