Upgraded to 4.2 and cannot send email via exchange 2003

[Pvrimes43]

I installed the new release 4.2 and have synced my outlook account. I can RECEIVE emails, delete, move folders etc. successfully. I can sync/add/delete calendar items. I can add/change/view all contact info.

I just cannot send email! Get:

Cannot Send Mail
Check the settings for the outgoing servers in Settings>Mail, Contacts, Calendars

My:
email
Server
Domain
Username
Password

all must be ok as I can sync everything, just not send an email from this account, either thru WiFI or cellular data.

Any suggestions? I dont see any options available to me to "adjust" outgoing server stuff...
