Hopefully somebody else has run into this before.

We have and Exchange environment where all the front-end and back-end
Exchange servers are on the same domain with the exception of one back-end
Exchange server. I am able to view and wipe phone on the domain where the
front-end is but users on the Exchange server on the other domain I do not
see and cannot wipe. We are in mixed mode as we are still migrating some
5.5 servers and will not be complete until the middle of 2007.

Any suggestions other than bringing online another front-end server and
going native.

Thanks,

Richard
