I'm in the process of migrating from Exchange 2003 to Exchange 2010. The new server is setup, all mailboxes have been moved to it, autodiscover and OWA are working properly, no problems.
Now the last step before I can decomission the old server are the public folders. When I try to right clic on the public folders database then move replicas to move them to the new server (on which I created a new public folders database), I get the following error :
"The HTTP service used by Public Folders is not available, ..." ID no: c1030af3
Googled that for two days now, checked ADSI Edit, the correct server names are set, checked in IIS on Exadmin and Public virtual directories, they are put on the correct values, directory security seems ok, all windows services related to Microsoft Exchange are running, but no luck.
I've read that public folders are not mandatory any more on Exchange 2010 (we don't have any public folders except the default ones created by the system, and don't have any Outlook client prior to 2007 version). So I thought, let's delete them and go on, but Exchange 2003 don't seem to let me delete them.
How can I get rid of that so I can decomission the old server and turn it off ? It's annoying me as I cannot create email address strategies based on organizational units because legacy servers are detected ...
