Outlook Everywhere cannot be used in windows Seven

So if we are using a hosted exchange service, I am, then we are out of luck unless it gets fixed in the next build or the host provider makes the necessary change on their side, correct?

Or try using Domain\User Name instead of just you user name at logon.

Just changing it to NTLM worked for me.

Hi had the same problems with "Basic" so I switched to "NTLM" as jmaga48 did and it worked for me also.
Thanks for the help.

I'm having the same issue with build 7000. I have Exchange 2003 running on SBS 2003 standard, I tried changing the authentication on the RPC folder under default website, and Outlook 2007 to NTLM but still no go.

I see there appear to be extra steps possibly for exchange system manager but they look like a later version than Exchange 2003.

Anybody know what needs to be done server side for exchange 2003.

I have alraedy run IE7 as administrator & installed the certificate.

Thanks in advance.

I have solved the problem, please see:

i had this problem appear after months of working fine. for some reason, clients machines were switching from our OWA site (webmail.company.com) to server.company.com on the exchange proxy settings of the connection tab. also, the "only connect to proxy servers......" box was checked off. this did not occurr manually, but happened somewhere in the background. easy to fix, but very strange that it happens at all.
