Here is the problem :
I activated Outlook Anywhere on my Exchange 2007 server, I can use it with an Outlook 2007 client (good certificate, NTLM authentification) but I can't with an Outlook 2003 client !
Outlook 2003 seems to try some connection on port 443 and then try to port 135 and fail (port 135 is blocked because i want to use 443 )
I can't find any solution...
Thanks in advance !
