Brian, I look back at your message "Are you saying those errors appear when
you expand the DL in the To field? That doesn't seem correct. "
I have refered to these as Contact Lists, changed from Group List since an
earlier response said Outlook doesn't use the term Group Lists. The term
DL?
Is DL a term for contact list?
Outlook does not use the term "Contact list". When you click File>New, you
won't see "Contact List" there, but you will see "Distribution List", which is
a Contact folder entry that contains a list of name/address pairs that can be
used in a recipient field just as a Contact name or an email address can be
used.
Before you send your message, if you enter something in a recipient field, it
must be "resolved" or converted to a n address. When that happens, Outlook
underlines the entry, signifying that it has found the matching contact's
address or, in the case of a DL, the list of addresses. For a DL, Outlook
will also place a plus sign in front of the name. If you click that plus
sign, the DL will expand to its component entries. There's simply no way
Outlook will display the errors you posted at that point, because the errors
you posted are server-side responses that happen only after you've sent the
message. That's why I questioned you and said something didn't seem correct.
In your latest example, it appears that the DL "A - DENIS-2 - POLITICOS" is a
Distribution List that contains the other lists "A - DENIS - OLD CUSTOMERS",
"A - DENIS - PROSPECTS", and "A - DENIS - REAL ESTATE SERVICE". If I were
experiencing what you describe, the first thing I'd do is remove those entries
from the AutoCompletion cache by entering the letter "A" into the To field of
a new message, which should cause a scroll list contaiining one or more of
these Distribution List names to pop up, selecting one of the list names in
the scroll list by using my down arrow key, then pressing Delete. Then I'd
try again, creating a new message, entering the DL name, pressing Ctrl-K to
force a new resolution, then composing the remainder of the message and
sending it again. If that still failed, I'd remove the Outlook Address Book
service from my mail profile and add it in again, remove any autocompletion
cache entries a second time, as described previously. This should start the
resolution process cleanly.
