January 29, 2007

If you try to add a Query-based Distribution Group to a non-Query-based/”normal” Distribution Group by going to group’s properties | Member tab | Add – the UI doesn’t list any Query-based Distribution Groups. One workaround I suggested recently is to add the distinguishedName of the Query-based Distribution Group to the member attribute of the normal [...]

Adventures with OPATH: some annoyances if you’re used to LDAP

January 29, 2007

If you’ve deployed or have been testing Exchange Server 2007, you must have certainly crossed paths with OPATH. OPATH is a querying language, somewhat similar to SQL.

Exchange Server 2007: Bulk creation of mailboxes using Exchange Management Shell

November 1, 2006

Bulk creation of mailboxes (and the accompanying user accounts) in Exchange Server 2003/2000 involved some elaborate scripting effort. This task can now be done fairly effortlessly, thanks to the Exchange Management Shell (EMS). The Shell can very easily import/use CSV files saved from a spreadsheet or text editor and create the mailbox-enabled users. Here’s how. [...]

Query-based Distribution Groups and Disabled Users

January 13, 2006

Another issue with Query-based Distribution Groups – when admins create these, typically using a GUI – there’s no obivious way of excluding disabled user accounts. Even if you enter the ldap filter manually using Custom Search, it’s easy to forget about excluding disabled users. End result: users sending mail to QBDGs complain about getting NDRs [...]

December 27, 2005

You create new Query-Based Distribution Groups but they don’t show up in the All Groups address list in Outlook clients – cached mode or not. QBDGs are not really groups, as far as Active Directory goes. They’re instantiated from a new class – msExchDynamicDistributionList.
