Outlook 2010 fails login to SMTP services on SBS 2008

I use POP3/SMTP connections to SBS 2008 of some Outlook clients. Instruction how to do it (on port 587 with SPA) i found in ANSWERS. It run wery good on Outlook 2003 and 2007, but not on Outlook 2010. Have anybody some suggestion how to resolve it?

i found this solution in a different thread:
I had to uncheck the "Offer Basic Authentication only after starting TLS" on my Exchange 2007 receive connector. After I did that, Outlook 2010 was able to authenticate properly.
Check your SSL settings.

Can you explain it? I try it on same computer (i.e. OS) and same account: Outlook 2003 is OK, 2010 not.
