External meeting attendee shows up 3X in booked appointment after accepting

[Phil McNeill]

I have an Exchange Contact in my Global Address List from an external
organization. When that external contact accepts a meeting request from me,
and then I go to open the meeting to edit it, they appear in the list of
attendees 3 times. Each of the instances of them as an attendee resolves
back to the same Exchange Contact, and I have no Outlook Contact for them in
my personal Contacts.

On the test meeting I created with them today which they accepted (once) I
see their name 3 times, with 2 of them listed as accepted.

Their Exchange Contact is a member of 3 different Exchange Distribution
Groups on my server.

This has of course resulted in issues when someone from my org sets up a
meeting with this person and then modifies it, as when they send the update,
the external user gets the update notification 3 times, making life
confusing.

Any idea on what's going on here? I've found this KB article:
http://support.microsoft.com/kb/924249/en-us that seems to address this.
Not sure if that's my solution or not. I currently do not have "Resolve
Anonymous Email" enabled on my default SMTP Virtual Server.

Version info:

Our end: Exchange 2003 SP2, Outlook 2000 as a client
Their end: Exchange 2003 SP2, Outlook 2003 as a client

Thanks for any insights!

Sounds like your issues, though I prob wouldn't enable anonymous
resolution. It looks like you will have to make the a decision on the
best two evils.


"Note Microsoft does not recommend that you turn on the Resolve
anonymous E-mail option on any Exchange computers that receive mail
from the Internet. If you turn on the Resolve anonymous senders
option, any user can send anonymous mail through the SMTP server, and
the mail message appears to the recipient as authenticated mail. For

Thanks,

Just so I'm understanding, the big difference once I turn this on is that
for any external senders that have an entry in my GAL (i.e. Exchange Contact
or formerly "Custom Recipient"), I'll now see their name on my message in MY
format as opposed to THEIR format with their email address in brackets
beside, the suggested danger of this being that my users may be more likely
to trust that the email is genuinely coming from who it says it's coming
from?

Question 2

Is it likely my problem of duplicate entries would go away if I simply
remove the Exchange Contact from my system and tell people to use an Outlook
Contact instead?

Thanks!
