Email Contacts Issue

Can contacts primary or secondary SMTP Addresses be changed via Recipient Policies without affecting normal users with mailboxes?

My problem is that there is tons of contacts that are having issues with duplicate SMTP Addresses as our valid users with mailbox accounts.

This is causing 5.1.0 NDR Messages. We think a script was ran to do this because Exchange does not allow you to get away with creating a contact with the same email address as a mailbox account.

Any ideas let me know. Thanks a bunch everyone

You would have to create a custom Recipient Policy to update the contacts only, but this would add to the existing addresses and not delete the existing duplicates. You will need to find the duplicates and change them.

If you have got duplicate e-mail addresses in your infrastructure there are three ways to remove these

1) Write a script in Perl or VBScript (or something else) to search all the objects with e-mail addresses to check which ones have duplicate addresses and then manually change them as required

2) Manually check all the objects and fix as required. Duplicate e-mail addresses will be logged in the Event viewer when e-mails are sent to users with duplicates

3) Use LDIFDE as per the article to extract the information and sort (this way is simpler if you do not have the time to develop a script to do the work)

Try the following - it is a explained in a much easier format:

Sweet I will save the LDIFDE link for later. I may still need to use it.

What I did was make a query for contacts proxy addresses and one for users. I'm downloading a doc compare tool right now so it can highlight the difference.

Thanks a bunch

Read the document.

Here is the problem with all these links. None of them show how to search ALL objects and spit out duplicates.

I'm sure I will need a script to do this.

Thanks guys

Ah ok I did a query and queried for exchange recipients, contacts, proxyaddresses value SMTP:*@Domain.Com* and did the same for users

Then I exported the list and ran a compare doc utility from the net.

Thanks
