Error: 'The HTTP service used by public folders is not available'

When I right click on a folder created on our Exchange public folder store, under the first storage group, I receive the following error:

"The HTTP service used by public folders is not available, possible causes are that public stores are not mounted and the information store service is not running."

I have checked both of these and this is not the case. The ID# is C1030af3. Microsoft has a list of possible causes, but they don't seem to be relevant to my problem. Can you help?

I suspect what you're seeing is MDAC-related, not related to Exchange Server. Have a look through Microsoft Knowledge Base article 301202 "How to check for MDAC version." Then, check the files on your computer to ensure they're all from a consistent version of MDAC, and not mismatched across different MDAC versions. I suspect that will fix your issues with Exchange System Manager.
