I ran in to a problem where I was trying to remove a public folder store from a front-end server. The SSL certificate on the front-end server is wrong (wrong FQDN/CN, unknown CA, and it is expired). I could not manage the public folder hierarchy using Exchange System Manager.
Depending on what I was trying to do, I got this error:
The SSL certificate server name is incorrect.
ID no: c103b404 Exchange System Manager
I also saw this error:
The token supplied to the function is invalid
ID no 80090308
Lots of newsgroup and web discussion forms pointed to this KB article indicating that the problem might be related to SSL being required on the /ExAdmin virtual directory. “You receive an SSL Certificate error message when you view public folders in Exchange System Manager” http://support.microsoft.com/kb/324345 I checked that and it was NOT the case.
Finally found some instructions in a newsgroup that worked. This requires ADSIEDIT and a little bit of Exchange configuration editing.
Run ADSIEDIT ( DOWNLOAD HERE: http://www.computerperformance.co.uk/w2k3/utilities/adsi_edit.htm )
Navigate to the following object: CN=Configuration, then CN=Services, CN=Microsoft Exchange, CN=, CN=Administrative Groups, CN=First Administrative Group, CN=Servers, CN=Protocols, CN=HTTP, CN=1, CN=Exadmin
Display the properties of the CN=Exadmin object
Locate the msExchSecureBindings attribute, highlight it and click Edit button
If it has a value of :443:, select that value in the Values list, click Remove.
Click OK twice and then close ADSIEDIT
Give this a few minutes to replicate through Active Directory and try it again!
