Ben - thank you for questioning me further regarding this subject. I have
figured out the problem and thought I'd post the resoultion here in case
anyone else has this issue come up...
I experimented with Outlook's options and noted that when I deselected
"always check spelling before sending" under the 'Tools' menu, 'Options'
option, 'Spelling' tab, I could then send. However, I then received a "error
when attempting to spell check" popup message after the message sent.
In further checking my Word options, I noted that the "Spelling and Grammar"
tab was deselected, and I was there were no dictionary language options to
choose from Outlook, so we reloaded Office Products. Problem solved - so
somehow my Word application became corrupted.
Thanks for your support
Sue
