I have rather a strange problem in that one of our remote sites (connected via Watchguard Site to Site VPN) are not able to connect to Exchange. Everything is fine apart from the Exchange connection so files, printing web etc are all fine. When the same laptops travel to our other sites they are fine??? And they can connect at home via PPTP. Incidentally, one of the members of staff rebooted (on Win 7) and then recieved a different problem and we had to rejoin. Although this action was successfully completed.....still no Outlook!! HELP!!
