Exch2010 pf-mails queued

Hi experts,

after a exch2010 -> exch2010 migration I shut down the old exch2010 server 2 weeks ago.
Before I moved all replica`s f public folders.

Now I`m recognizing emails in a queue called "oldserver" where the new public folders database tries to send emails with following subject to the old publci folder database:

- Status
- Hierarchy

The queues persist as the old server is not reachable at the moment.

This queue only contains 1 mails at the moment and it doesn`t seem to influence an mail-flow.
But I`m wondering why those mails get sent by the new server.

I`m planning to uninstall the old server in a few weeks. After that those mails should stop.

Do I have to worry about those mails until I can uninstall the old server? How often get those mails sent? Is there a risk that those mails in a queue influence my regular mail flow?

Is there a way to have my new server stop delivery of those mails to the old server?
Will unsuccessfull deliviered mails automatically be deleted from the queue after a count of attempts?

Best regards!

It is possible you have any Public folder replica on old server? Usually this messages are changes on public folders.

No, I tested following:

Get-PublicFolder -Recurse | fl name,replicas
Get-PublicFolder -Recurse \non_ipm_subtree| fl name,replicas

Open in new window

All folders show:

Replicas : {New_PF_Database}

There is no entry to the old server...

OK, increased the log level but by now I don`t see any log entry about that in aplication log.

In the queue there is only one message. This has been sent on September, 1st 2013, 02:15:01 AM.

This message will expire on September, 3rd 2013, 02:15:01 AM.

Would this that the non functioning queue will disappear on 3rd and the message will be deleted?

I will let my logging level for pf replication on high and hope that won`t give performance or disk space issues.

Has anybody experiences with queued messages? Do I have to care about retrying as far as I don`t need those messages?

I had similar problem twice during migration from 2003 to 2010. On first time was one public folder replicated on old server. On second case, was disappeared when remove completely old exchange server. Those messages are simply emails with data, synchronizations between servers, populate databases or whatever. Do you remove all databases on old server? maybe this messages are cause by this.
If you have shutdown your server and all services are running fine, I would not worry.

You need to remove the old server.
Exchange still thinks the server is there and will try to send content to it. Shutting down a server doesn't really work with Exchange. You should start the server up and remove it correctly, then those messages will go away. Until you do, they will continue to occur.

OK, I know. And I`m planning to uninstall it in a month.
I`m going on holiday fpr two weeks next week so I don`t have the time uninstall the server now.

I think this non functional queue won`t cause any issues to our email organization beacause it is no mail which any information we need.

I`d just like to know how the server will bevave during the two weeks. If it sends one to three emails to this queue every week there won`t be a problem the next weeks.

Will the mail be deleted and the queue be closed as soon as the mail expires?

Best regards!

If you are going on holiday for two weeks I would suggest starting the server up and leaving it up so it doesn't cause problems while you are away. The queues will expire over time, but they will just be repeated over and over again. If there is a problem while you are away and someone else looks at the server then they will see that and think it is a problem. Simply by bring the old server back online will stop the issues from occuring.

My preference would be to either find the time to remove the server properly, or have it left switched on. Turned off/Exchange services disabled is not something I would even consider.

Thanks for your suggestion.
Since 2 days there have been no Messages in a Queue and the past 3 weeks I even didn`t recognize any.

The last queued messages disappeared after 2 days by theirselves.
And since the old Server is offline, I couldn`t find any problems in mail flow or connection.

I´ll tell my my colleages to regularly have a look at the queues.
