I have installed Exchange 2007 + SP3 (All Roles on 1 server) onto a Windows 2008 R2 Server Member Server (after all pre-reqs met)
On Windows 7 client (or Windows XP) I have Outlook 2007 (using cached mode - but also tried with this turned off), and as an AD user with a mailbox created on the Exchange 2007 + SP3 Server I can configure Outlook 2007 to connect to my Exchange 2007+ SP3 Server and can access the Mailbox (and ran Test on Outlook config to find SCP etc. and this is OK). I can access the GAL and can compose and Send an e-mail. Copy of the e-mail goes into the Sent box (via a Web Browser i.e. OWA mail ends up in Drafts folder), buy when I logon and access the mailbox of the user the e-mail was sent to, they have not received the e-mail.
Any Ideas ?
Note - With Exchange 2007 + SP2 this unable to receive e-mails is not a problem either in Outlook or OWA
