Exchange Partner Store Upgrade Question?

[teid]

Currently running Unity 4.0.3 UM with Exchange 2K off-store.

The Exchange partner server is being upgraded from 2000 to 2003. Most user mailboxes are on this server.

1. When do we need to change the Unity Partner Exchange from 2000 to 2003? We need to keep the same partner server.

2. Do we have to do it before the partner upgrade or can we wait until after?

3. If we do it after, can we wait a couple of weeks or we would need to do it immediately after so Unity can function.

Thanks,

Tony.

Check out the reconfiguration and upgrade guide here:

It includes instructions on how to upgrade the partner server to 2003

Once you upgrade the partner server to Exchange 2003 Unity will not be able to talk to it until you install the Exchange 2003 Messaging Tools on the Unity server and reboot.

Thanks,

Thank you for the responses.

Just to confirm. I take it I can't do this ahead of time, i.e. run the Message Store Config Wiz until after the partner server is upgraded to 2003. I just need to do it immediately after in order for Unity to talk to it.
