On my network, I have some laptop with Windows XP and Windows 7 client using outlook 2007 and exchange server 2003. Protocol used is exchange basic protocol (MAPI ?)..
Within the company, users use outlook 2007 with no problems and exchange 2003.
By the vpn, Windows XP notebooks can connect to exchange server 2003 without problem too.
But the problem is laptops with Windows 7 can not properly connect to exchange server 2003 through vpn. The temporary solution I found is to use IMAP but I wish I could use the standard protocool of exchange.
Please help me
