Hi,
I have a problem using “Import From MS Exchange Server (2010)”, I get the message “error # 1090 null”.
I want to know what ports are used to connect with exchange (we have open ports 445 and 25)
details:
1 / the exchange server is on another site
2 / there is no VPN connection
3 / OWA connection only
thank you
PS: sorry for my grammar, I’m french …
