80090308 "The token supplied to the function is not valid"


The customer was getting the above error when clicking on Public Folders in Exchange System Manager.  He was also getting the following error when running the Add Distribution Group wizard and selecting to create an "archive public folder":


Add Distribution Group Wizard
The wizard could not successfully configure this group. The following could not be completed:


- The Exchange public folder could not be created.


Do you want to keep this group?
Yes   No  


This article was followed without success.  What we did to resolve it was to remove a value in Active Directory using ADSIEdit.  We had to install the Windows 2003 Support Tools to get access to ADSIEdit.  With the SBS 2003 media, the support tools are located in cd2\support\tools\suptools.msi.  The attribute is msExchSecureBindings.  The value is :443:.

We right clicked on Exadmin and clicked Properties.  We scrolled down until we found msExchSecureBindings and clicked Edit.  By default, the value was/is :443: - we clicked to highlight :443: and clicked Remove.  It then showed <Not Set> for msExchSecureBindings.  We then restarted the Microsoft Exchange System Attendant and then restarted the IISAdmin service. 


For all you (us) geeks, here is the full "distinguishedName":  CN=Exadmin,CN=1,CN=HTTP,CN=Protocols,CN=SERVER,CN=Servers,CN=first administrative group,CN=Administrative Groups,CN=COMPANY,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=company,DC=local


The root cause is because the certificate that was installed in IIS did not contain the "servername" in the "subject" field (you have to view the certificate and click the details tab to see this field).

Other errors per this article are:

The SSL certificate server name is incorrect.
ID no: c103b404
Exchange System Manager

The connection was aborted. Ensure that the settings on your default Web site are correct and refresh the Public Folder Tree
ID no: c103b402
Exchange System Manager


Have a good weekend!

    Great – fixed problem straight away, after having spent several hours trying to resolve why I couldn’t get to the public folders on the exchange server manager.

    All other suggestions, also as mentioned in KB324345 did not work for us.

    thanks very much, this is the 6th or 7th article I’ve looked at and the only one thus far gave the correct answer my case.

    Cheers Peter, worked a treat.

    NB: I made the edit and did an "iisreset /restart" — All tested and working (ie. no requirement to restart exchange services)

    I also had this issue on an SBS Standard system but initially the above solution did not resolve the problem.

    In this case there was a self signed certificate of say server.internalname.local and a purchased certificate of server.internetname.com. When I changed the IIS certificate back to the self signed one it all started to work thus proving that it was definately the certificate causing the problem. IIS restarts, System Attendant restarts, server restarts did not resolve the issue.

    The ‘Require secure channel (SSL)’ settings had been removed and the ADSIEdit msExchSecureBinding setting was clear.

    However, by changing the certificate back to the self signed one, and then back again to the secure external one the ADSI settings had been changed. This time clearing them did the job.

    So if you still have problems try this:

    1. Remove the ‘Require secure channel (SSL)’ setting as above.

    2. Change the IIS certificate for the Default Web Site back to the original self signed certificate.

    3. Test the System Manager to make sure you can now access the Public Folders, this ensures that the SSL certificate is the real cause of the issue.

    4. Change the SSL certificate back to the external secure certificate.

    5. Restart IIS with iisreset /restart.

    Run ADSIEdit in teh mmc console and remove the msExchSecureBinding setting as above.

    6. Test the System Manager again, with luck all should be well.
