Hello,<br />
<br />
We have an instance where we need to migrate a few SBS 2003 users to SBS 2008. &nbsp;As part of the process, I created a &quot;proxy Address&quot; in the SBS 2008 server for the Legacy DN of the old server, so that they could reply to old emails, etc.<br />
<br />
The next day this stopped working, so I checked and my addition to the ProxyAddress field is gone. &nbsp;<br />
<br />
Any idea what erased it, and how to prevent it from happening again?<br />
<br />
Thanks,<br />
Mike

Hello,

We have an instance where we need to migrate a few SBS 2003 users to SBS 2008.  As part of the process, I created a "proxy Address" in the SBS 2008 server for the Legacy DN of the old server, so that they could reply to old emails, etc.

The next day this stopped working, so I checked and my addition to the ProxyAddress field is gone.  

Any idea what erased it, and how to prevent it from happening again?

Thanks,
