OL 2002 SP3
Win XP HE SP1

hi,
i am new to IMAP.
1) i set up 1 email account and saw that OL creates a pst file just for
that account--which i find weird.
2) then i saw that OL stores the "sent" items in folder "sent" local
folders....weird.
3) then i had a problem as i chose to connect thru SSL with this error
message appearing: "the server u r connected to is using a security
certificate that cd not be verified. a certif chain processed, but
terminated in a root certificate which is not trusted by the trust
provider. do u want to continue to using this server?

i checked with host and that setup (not sharing certificate, etc.) is
normal.

how do i set up OL NOT to display this error message everytime i open
OL--every session?

tx for ur comments to my above 3 points.
