GAL Issue with Exchange 2010

Guys,
 
 I am currently using Exchange 2010 with HC8 Build 9 and GAL is not working in exchange 2010.  Can someone help me asap?

Awesome... Thanks

I have migrated from Exchange 2007 to 2010 but still having issues with it. I asked HC support and according to them I would have to recreate separate GAL for Exchange 2010. Cannot I use the old GAL of Exchange 2007?

You are getting this issue because in Exchange 2010 SP1 msExchQueryBaseDN attribute should be empty, this is a bug in Exchange and we have given a workaround to clear this attribute. We have fixed this issue for new mailboxes for existing mailboxes you can run following PowerShell script to clear ‘msExchQueryBaseDN” for all mailboxes in Hosting OU (i.e. created by HC)

get-mailbox -organizationalUnit "Hosting" |Foreach{ $dn = "LDAP://" + $_.distinguishedname;$obj = [ADSI]$dn;$obj.msExchQueryBaseDN.Clear();$obj.setinfo()}

Note: Run (copy/paste ) this script in single line in Exchange power shell, otherwise it won’t run.

Or
If you want to execute the query against a particular domain then follow below command

get-mailbox -filter {Alias -like '*_domain.com'}|Foreach{ $dn = "LDAP://" + $_.distinguishedname;$obj = [ADSI]$dn;$obj.msExchQueryBaseDN.Clear();$obj.setinfo()}
