DST2007 CDO patch: Hotfix released for Store not mounting issue

After applying the DST 2007 CDO patch for Exchange (includes Store.exe v 06.05.7651.61) on Exchange Servers 2003 SP2, the Store does not mount. This happens in environments with more than one domain where a well-known SID like BUILTIN\Administrators is included in Exchange permissions, and the Store.exe is version v06.05.7651.26 or later. KBA 930241 outlines a […]

DST 2007 and Exchange 2000: Patch For A Price?

IT folks in many organizations still on Exchange 2000 are upset about the fact that Microsoft isn’t providing the DST 2007 CDO patch for Exchange 2000 for free, unlike the ones for Exchange 2003. (Exchange Server 2007 does not require it). If you’re still on Exchange 2000, and upset about the price-tag of this patch, […]

OPATH: Filterable properties that can be used in Recipient Filters

Exchange 2007 uses OPATH filters to filter recipients for things like Email Address Policies and Query-based Distribution Groups. Earlier I’d written about my adventures and annoyances with Exchange’s OPATH filters and the recently added support for memberOf attribute in OPATH filters.

memberOf Attribute can now be used in OPATH filters!

I’ve blogged about OPATH filters before [read previous post “Adventures with OPATH: some annoyances if you’re used to LDAP“], and one of the annoyances was the the fact that it wasn’t possible to use the memberOf attribute to pick up (or exclude) members of certain groups from all the stuff that uses OPATH filters such […]

Offline Address Book: Mystery of The Missing Recipients

Frequently users report recipients missing from the GAL. So begins the mystery of missing recipients. These are existing users, not new ones. New users don’t show up in the GAL for clients using Outlook 2003 Cached Mode clients, because Outlook uses an Offline Address List (aka “Offline Address Book” or OAB), which is generated once […]

Messaging Hygiene features in Exchange Server 2003, including the Intelligent Message Filter (IMF), did not have a way to whitelist sending domains or SMTP addresses.

HOW TO: Add a Query-Based Distribution Group to a (non-Query-based/”normal”) Distribution Group

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 filters in Exchange 2007 and some annoyances if you’re used to LDAP

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. It is used to filter objects in PowerShell.

Double-checking on some servers, I’ve noticed this – the last update that shows up on those in Add/Remove Programs is dated 8/10/2006.If you look at the registry key for this update […]
