Exchange Public Folder Mount Error
Another Exchange specific issue: we had a problem after migrating to Exchange 2010 and then uninstalling Exchange 2003, eventhough replicas of public folders were moved to the new server. Errors would show in the Exchange System Manager, and the following message would occur:
MapiExceptionADPropertyError: Unable to mount database. (hr=0×80004005, ec=2418)
There is a excellent post on TechNet Forums about this topic. However, it does not include information for Exchange 2010, and mentions to restart the Information Store, when restarting the System Attendant is sufficient. Corrected instructions below.
Open ADSI Edit, connect to a Domain Controller, change the context to Configuration.
Create the Folder Hierarchies under the Exchange Administrative Group
- Navigate to Configuration ⇒ Services ⇒ Microsoft Exchange ⇒ <Exchange Organization> ⇒ Administrative Groups
- Right click on <Exchange Administrative Group> and select New Object
- Select msExchPublicFolderTreeContainer as class and click Next
- Enter the following as value: Folder Hierarchies, click Next, Finish
Create the Public Folders Tree Object
- Right click Folder Hierarchies and select New Object
- Select msExchPFTree as class, click Next
- Enter the following as value: Public Folders, click Next
- Click on More Attributes button, select msExchPFTreeType and set the value to 1
- Click OK, Finish
Populate the msExchOwningPFTreeBL attribute object of the PF Store
- Double click the newly created “Public Folders” object
- Double click distinguishedName, copy the value to the clipboard, click Cancel
- Exchange 2007: open properties of Configuration ⇒ Services ⇒ Microsoft Exchange ⇒ <Exchange Organization> ⇒ Administrative Groups ⇒ <Exchange 2007 Administrative Group> ⇒ Servers ⇒ <Affected Exchange Server> ⇒ Information Store ⇒ <Storage Group> ⇒ <Public Folder Database>
- Exchange 2010: open properties of Configuration ⇒ Services ⇒ Microsoft Exchange ⇒ <Exchange Organization> ⇒ Administrative Groups ⇒ <Exchange 2010 Administrative Group> ⇒ Databases ⇒ <Public Folder Database>
- Double click the msExchOwningPFTree attribute, paste the value that was copied to the clipboard in step 2
- Click OK twice
Try to mount the Store
- Restart the Microsoft Exchange System Attendant Service
- Open Exchange System Manager and try to mount the PF store

Wow thank you, this worked perfectly.
I don’t see the msExchOwningPFTree Attribute?
Maybe it isn’t shown due to your filter settings. Make sure you clear out any filters that might be enabled.
you rock man, thank you
Thanks, this worked! Out of the blue the msExchOwningPFTree item was “not set”. Pasted the value, restart system attendant and I could mount succesfully.
Absolutely superb – worked with Exchange 2010. THANK YOU! Great article.
I’ve just removed an Exchange 2007 server from my org and public folders failed on the remaining 2010 server. Fortunately your article has saved me from a serious flaming! Many thanks. :)
Great Article, you saved my day, many thanks:))
I apprecitate to this posting.
Our Ex2007 had a same symptoms and it`s gone by applying this recipe!! :)
Excellent !!!
has few hours i am looking for it.. and now my EX2010 is fixed !
Thank you for this article. Worked perfectly and allowed my public folder store in Exchange 2010 to mount straight away.
Hello, I can not find the msExchOwningPFTree attribute.
I have played with the filters, but still not showing up.
That worked. Thank you. Great work
Dude you rock
Thanks for this fix. It works
Wanted to say THANK YOU very much as well. After removing our old Exch 2003 suddenly our PF’s went down and I was frantic. This solved it!
Thanks a lot!
I also don’t see the msExchOwningPFTree attribute after resetting the filter….
Hm, it should be there. What is your current AD functional level?
Fixed my problems, Thank you
If you dont see the msExchOwningPFTree attribute then you’re looking at the wrong object.
When looking at Administrative Groups ⇒ Databases ⇒ CN=Your Public Folders Database, dont look at the properties of CN=Public Folders object in the right pane, look at the properties of the CN=Your Public Folders Database object in the left pane. You’ll find the attribute there. I made the same mistake myself.
AWESOME article. Saved my day.
After finding msExchOwningPFTree my life goes on ! AWESOME
This worked well for me and my PFs are mounted. However, when I open the Public Folder Management Console, I get this error:
Couldn’t find a MAPI public folder tree. It was running the command ‘get-publicfolder -getchildren -identity ‘\’ -server ‘myserver.mydomain.local”
Any ideas?
Update: I found a post here:
http://social.technet.microsoft.com/Forums/en-IE/exchangesvradmin/thread/cede8832-a434-4e80-b45c-433bd8daf4f0
This cleared up my problem with the PF Management Console in the Toolbox. You may wish to update your post with the correct information below.

After compared the setting in the lab, I found that the class of “Folder Hierarchies” shall be “msExchclassContainer” instead of “msExchPublicFolderTreeContainer”
Thanks, thanks a lot.
This is a terrific article. Thank you, thank you thank you!
Good work, you saved my life!!!
My Boss would kill me, if we loose 12GB PF Data…
Thank you for the fix.
Very straight forward guide. You should write KB articles for a living :)
Thanks for this article. It worked. I would be happy, if i could see empty public folders, but suddenly old folders also appeared, which was even better.

Holy fishsticks! It worked like a charm. I tell you, it’s a dark place over there, in the bowels of the AD.
Thanks man!
You’re a life safer!
This is great!! It works fine. I had to change the filter to see the msExchOwningPFTree.
Thnx!!

Great artikle, was able to get the PF up and running in no time with these instructions.
The issue had occurred after doing a manual uninstall of an old Exchange 2003 server. This server could not be uninstalled due to the PF aswell.
This article just saved me my life, thanks to God ! and thanks AlanD and the writer of the article !!
