SBS 2003 Server XXX.local is the domain and they bring mail into them for their XXX.com domain, there is also a small 2nd business in the company called YYY and the same SBS server also brings in mail for YYY.com. (All users in same office using same server and broadband)
YYY would like to separate its mail from the XXX Server but would like to keep using the SBS server to share files with XXX.
I got them to purchase Microsoft 353 hosted mail and I setup YYY.com on it last week, I configured the mail accounts in 365 for the 3 YYY users and got the IPS to setup the mx records and the dns settings.
I was on another site when the dns settings were completed so I did a test setup in Outlook 2007 of one of their accounts on my own laptop and the autodiscover worked and mail setup perfectly.
I then used logmein to connect into the laptop of one of the YYY users and setup a 2nd mail profile on his laptop for the YYY.com mail and the autodiscover did not work, it kept asking for the username and password, I then tried to manually setup the account using the settings from my laptop that were created but again it kept asking for the username and password.
I am wondering if the sonicwall onsite for the XXX.local domain is blocking the 365 mail ?
There are rules on the sonicwall -see below
1) Port 25 Allow Mail in from Postini IP range to SBS server ALLOW (Allows in mail for XXX and YYY.com but only from Postini)
2) Port 25 Mail Allow in from Postini Backup IP range to SBS server ALLOW ALLOW (Allows in mail for XXX and YYY.com but only from Postini)
3) Port 80 Allow WAN to LAN SBS Server – for OWA and iPhone I think
4) Port 443 Allow WAN to LAN SBS Server – for OWA and iPhone
5) LAN to WAN * - Allow
6) WAN to LAN * - Deny
Or do I need to remove YYY in the XXX.local exchange manager?
I will be onsite in a day or two again so any tips would be great.
