Mail Enable a Public Folder on Exchange 2003

I am trying to Mail Enable a Public Folder on Exchange 2003.  Which seems to be a simple task. However I am receiving the following error when I attempt to access ANY public folder Properties or click on All Tasks in Exchange System Manger. The Error: The Token supplied to the function is invalid. ID NO 80090308E Exchange System Manager.  
I have read other posts but their solutions did not correct this issue.

Thanks

Opened Adsiedit.msc.
- In the left side pane expand the Configuration container.
- Next expand CN=Configuration
- Then CN=Services
- CN=Microsoft Exchange
- CN=<your organization name here>
- CN=Administrative Groups
- CN=First Administrative Group
- CN=Servers
- CN=Protocols
- CN=HTTP
- CN=1
- Right Click on CN=Exadmin and choose Properties.
- In the Properties dialog box > Attribute Editor Tab> Go through the Attribute
list and scroll down to the attribute "MsExchSecureBindings" and double click on
it.
- If this attribute is set to :443 or any other value , click the :443 value to
select it and click the "Remove" button also remove it from the Add Value: box.
- Then click "Apply" and then "OK"
- Close out of ADSI Edit, close and reopen Exchange System Manager and test Public
Folder access again.

now expand public folders in Exchange System Manager

Thanks! That did it. Nothing was set under Adsiedit.msc. But I did change the settings under the Default Website.
