Not able to connect to public folder


Every time a user logs on to exchange 2010, they are unable to connect to public folders.

mail02.domain.local     Public Folders    Connecting

Then after a while it stops trying to connect, and there are no public folder access. We dont really use public folders, as all clients use outlook 2007, but while trying to connect, the users inbox are not updating, which is a big problem, its like a 30-60 sec delay every time they log on.

The old exchange 2007 server has been decomissioned.
The public folder hiarchy seems to have replicated as it should.

We have one server holding the CAS/hub transport service, and one server with the mailbox service.

Ok, i installed a second mailbox server, setup public folders, and moved clients there, that works fine. I was about to setup that server anyway, to use DAG, so no need to spend more time it this issue - i thank you for your help
HI ZitCom,
Please use the following command to Give/Update permissions on public Folder
Add-PublicFolderClientPermission -Identity "\Marketing\West Coast" -AccessRights "RightsThat NeedtoBeGiven" -User Kim

I tried running the following commands:
Add-PublicFolderClientPermission -Identity "\internet newsgroups" -accessrights owner -user testuser
Add-PublicFolderClientPermission -Identity \NON_IPM_SUBTREE -accessrights owner -user testuser

both completed successfully, but the issue is still the same, Outlook tried to connect to public folders, but times out after a while.

In Outlook, when i try to connect to the public folder, i get thie following error:

Is this your new Mail server "mail02". It looks like the Old public Folder replica instance was not cleaned up properly.
ZitComAuthor Commented:
Yes mail02 is the new server.

That could be, i just checked the folder hiarchy was there, then i removed the previous mail server.
Any idea on how to fix this?
As mentioned earlier, we dont have much use for public folders, i just installed them because i had some trouble uninstalling the old server otherwise.
Perhaps i should just try and remove the public folders, users should not be affected by this, since they are not connected to the folder?
Check the client settings on the properties of your mailbox database. See what public folder database it refers to.
ZitComAuthor Commented:
That refers to the correct public folder database on mail02.

I just noticed that i am able to browse public folderse from OWA. just created a folder and a message with one user, and read it with another.

Are you able to browse any old folders ? It really looks like the CAS settings are not proper.
ZitComAuthor Commented:
the only old folder there is, is the default "internet newsgroup" folder, i am able to post message there.

I noticed one thing, not sure of it matters or not.

When checking public folder management from the toolbox, the system folders are located in \NON_IPM_SUBTREE.
When running get-publicfolder |fl - i get the following output, please note the name.
