I am running a Microsoft Exchange 2000 server with Outlook Web Access. We have several clients at a remote site who are not linked via VPN (or otherwise) who use this as a primary means of checking their company mail. Lately, several of these clients attempt to login to their mailboxes and other users (from the same location) mailboxes will appear. This is obviously a major problem. The users are working on their own machines...so it's not a local caching issue.
Could the router be caching this information?..or might this be an issue on the exchange server itself.
Any and all help would be greatly appreciated.
