Hello, I get these warnings on my Active Node SCC - Exchange 2007 SP2. Event Type: Warning Event Source: MSExchangeSA Event Category: OAL Generator Event ID: 9323 Date: 8/16/2011 Time: 6:10:13 PM User: N/A Computer: SCC-1 Description: Entry 'Smith Hang' has invalid or expired e-mail certificates. These certificates will not be included in the offline address list for '\Global Address List'. - OAB1 Offline Address Book There are loads of users which have expired certificate, I cannot manualy visit each user in AD and remove the expired certificates. There must be a way to remove automatically or some regedit!!!! I am also looking to remove expired certificates from my CA Admin Console to see if this will fix this issue too. Advise is appreciated. Thanks!!!

What did you use to put those certificates in originally? You can write a script that clears that certificate property in AD for all users, but I don't have a sample, sorry.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

This might be a place to start if you want to try your hand ad scripting a way to deal with them (or searching further to se of some's already written something): http://blogs.technet.com/b/exchange/archive/2005/07/25/408188.aspx --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
