Hello All, I have been notified by a customer that their OAB stopped working recently. Some google and an attempt to browse to the the xml file gives me an HTTP 500 error, some suggestions are missing authenticated users on the OAB folder/subfiles. I logged on to the server and went to access the Client access subfolder to get to OAB and was presented with the “you need permission to access this folder” and hit cancel (domain admin account, enterprise admin and exchange org admin memberships verified.). The same for transport roles folder, which I know doesn’t usually prompt as I go in here for log troubleshooting. The only thing I can think of here is a possible windows update!? Naturally I am completely unsure how to go about this. I suspect PSS is going to have to step in. I can’t even think we can even apply a new CU down the road without total failure and its way behind, I think CU5 or so.
