I downloaded 2010 Beta bits from MSDN yesterday and installed over Office 2007. Upgrade was successful. The new Outlook interface is neat! I know there are several new features and by default it now sorts by Conversation & Date, which is how I prefer to read my e-mails, especially at work. It helps me to see the whole thread on a subject.
The only problem I have had was when receiving the e-mail. By default, Outlook 2007 used the following ports
POP3: 995 (SSL)
SMTP: 587 (TLS)
as per Gmail documentation
Outlook timed out sending e-mails with these settings. I tried a couple of times but I kept on getting time-out messages with an error:
Task 'smtp server name - Sending and Receiving' reported error (0x8004210): 'The operation timed out waiting for a response from the sending (SMTP) server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'
Message seems a bit generic as Microsoft listed this as an issue message for Outlook 2002. Anywho, problem is solved now but I am not clear what did the trick. Here is what I did:
Changed SMTP to : 465 SSL
After e-mail was successfully sent, I changed SMTP back to 587 (TLS). It is still working. Go figure!
