LegacyExchangeDN's behavior

Hi there,

I have a requirement of importing mail enabled contact objects (from various domains) into our domain so it is easy for Outlook of our domain users to resolve other domain users.

There is a text file which has the contact objects (from other domains) which gets updated on a weekly basis with:
- new contact objects
- modified contact objects and
- deleted contact objects

I developed a solution which detects the above updates from the text file and make necessary amendments (creating, modifying or deleting contact objects) to our AD. But, I am noticing that LegacyExchangeDN's value of email enabled contact objects:
- gets added with an integer '1' at its end and
- that integer increments randomly

This is very random and intermittent - certain contact objects don't have the integer, but, some do. I am on Exchange 2003.

Can someone explain to me as to why I am seeing the above.

Cheers to anyone who can help on this.

Thank you both for your responses.

Rancy, some LegacyExchangeDN values have numbers higher than 400000. My understanding is that Recipient Update Service will be incrementing these numbers, but, I am unable to figure out 'why' and 'how' could a number grow more than 400000.

Have you any thoughts on this please?

Now thats what i call wired as it could be due to some 3rd party as i havent seen Exchange do such a thing as i have worked with tons of clients
