All staff mailboxes are on exchange 2003 server

Staff is using office 2007 & 2010 (soon everyone will be moving to 2010)

We are moving to Exchange 2010. We have installed the server but we do not have the san certifcate yet. THe exchange 2010 server has no mailboxes either

In the meantime users are gettng security alerts from our exchange 2010 server regarding certifcates every time they start up outlook

Is there an stop the security/certificate prompts from exchange 2010?

Since you installed exchange it is now the CAs server for the domain, the client are hitting it and then being redirected to the 2003 server.
Here is a good guide on getting the correct server certificate installed. The easiest way is to just get the correct certificate on the 2010 server

The problem is we don't know when we'll get the digital certificate from the Certification Authority. It's not up to me, it's management that needs to approve it. I can run the "New Exchange Certificate" wizard but since i can't import or bind it I don't see how it will help me

Okay so no mailboxes on 2k10 server is mail flow actually going through the server (have you changed the firewall rules to point to the new server?) If not can you not just shut the new server down...........

Firewall is still pointing to the existing windows 2003 server, so no mailfow is going to the new server. We could shut down exchange 2010 but it may be down for 1 or even 2 months at which point AD may remove the server. Management is slow

Is it a domain controller? I can be turned off for up to 59 days (tombstone) Just make sure it gets booted every three weeks or so if it is a domain controller. You could also just stop all exchange services on the server.

it's not a domain controller just a regular windows 2008 server running exchange 2010. I wasn't sure if stopping the exchange services will stop the certificate prompts but if it does that might be the perferct solution

Give it a shot.
You may need to close and reopen outlook on the client machines
