hi all,

My email client [entourage] worked fine with Corp. Exchange server until last month i ran into an error of Unable to establish secure connection because correct root certificate not installed. I ignored and went on then all my emails got deleted (didn't have a chance to backup as all emails removed from the server).

I tried to upgraded to 10.6 (from 10.5) and still have the same error of root cert.

I'm not sure what caused the auto deletion of emails. Is it because of the invalid root cert? And why suddenly i got this error?

thank you,
