group list email won't transmit

[NikkiMo]

"an unexpected Error has occurred", often pops up when I try to transmit my
group emails in Outlook 2007, XP/ Then it won't show up for awhile. I have
often had to send these groups one by one, taking forever.

Your post contains no information any of us could decipher. "transmit my
group emails" means nothing to us. Nor does the rest of your post.
Read the following, then create a post that uses actual Outlook terms we can
all understand.
