A Public Folder permissions issue


This is an issue that was discussed recently on the Mark Minasi forums (http://web2.minasi.com/forums) which I thought might help others with similar public folder permissions problems.


The issue was that an Exchange server had a functioning e-mail enabled public folder on an Exchange 2003, where some user can read and some can delete?content. It was created and configured before I the current administrator started the job.

At this point there came the need to?give another user?the delete permission. The problem was, that when the admin clicked on the?”Client Permissions” button in System Manager for this folder, the dialog box “Client Permissions” has no entries at all. And that’s strange, since the permissions once granted seem to nonetheless be in effect.

One thing that stands out with this particual folder, is its owner (otherwise there are nothing out of the ordinary with it). The (AD) owner of this folder is MY_OLD_SRV$, wherefrom it was once migrated. Other folders have either MY_CURRENT_SRV$ or SYSTEM as owner (even those created on the old server).

Having looked at this is seemed that maybe something had been corrupted on migration. I suggested that the admin should try to recreate the correct permissions.

When the admin tried adding permissions he found that he couldn’t add any entries in Client Permissions. When clicking OK, he got the following error message:

“Invalid windows handle
ID no: 80040102
Exchange System Manager”

While not wholly satisfying, at least this?provided something to Google for. First stop was Q313333, in which a tool is discussed, PFInfo, for exporting, editing, and importing permissions. Thing was, it’s not downloadable, but you have to call Microsoft and ask for it.

So a little more?Googling turned up a blog entry?(http://hellomate.typepad.com/exchange/2003/10/the_pfdavadmin_.html)?where another utility was discussed, PFDAVAdmin, which you can use to manage public folder permissions etc, and this was downloadable from Microsoft.

Having?downloaded and installed the tool it was then possible to check the actual Client Permission-entries for the folder with this utility, and also edit them without any trouble.

Now everybody is happy.


It has been brought to my attention that this tools is now available here:



Hope this helps someone,
