When I try to work in Public Folders inside of System Manager, I get prompted for a username and password on every item I try to open. I think it may be an IIS setting (not sure) because it started after making a change that allowed users to access Public Folders via OWA. This change was not documented, and it happed a while back, so I don't have much information to go on. Any help will be appreciated.

Jason, I am having this same problem. Did you have any luck getting it fixed? Dallas

One thing to check is too see if the web address for public folders is located in your trusted internet locations in IE.
