undelete

Tom sent me some interesting links just in case you toast e2k7 users by mistake :-| Not tested this yet, but might just for the fun of it in my lab

Undelete the OU/Users/Groups via ADRestore.net (http://blogs.microsoft.co.il/files/folders/guyt/entry12573.aspx)

– or –

ADRestore v1.1 (http://technet.microsoft.com/en-us/sysinternals/bb963906.aspx & http://support.microsoft.com/?kbid=840001)

Then reset password, enable account and re-attach the mailbox.

Exchange Server Remote Connectivity Analyzer

This is really good.  I have used it before and it looks really sweet now

Check it out: Announcing the release of Exchange Server Remote Connectivity Analyzer and https://www.testexchangeconnectivity.com/

Have you ever installed an Exchange server and wanted to verify your Internet facing services were setup and configured properly? Things like Exchange ActiveSync, AutoDiscover, Outlook Anywhere (RPC/HTTP), and inbound email. Sure there are cmdlets included in Exchange 2007 like test-ActivesyncConnectivity and test-OWAConnectivity, but these tests can only be run inside your network and effectively only test your internal network connectivity. Or what if you get a call or an escalation regarding one of these services not working? How do you verify if just this user or everyone has a problem? And if there is a problem, where do you start troubleshooting? Is it a DNS problem? Is it a certificate problem? Is a port not open on the firewall?
