Exchange 2010 Gotcha - #5
You may - or may not - need to register Filter Packs after you install them.
As a prerequsite for installing Exchange 2010, you must install the Office 2007 Filter Packs. As noted in a recent blog post of mine, Office 2010 Filter Pack for Exchange 2007 and Exchange 2010, the Office 2010 Filter Pack was recently released. After installing Exchange 2010, you can upgrade to the Office 2010 version of the filter pack (and this is also supported for Exchange 2007).
It may be that Exchange 2010 SP1 will require the Office 2010 version of the filter pack.
However, it has recently come to my attention that installing the filter pack, regardless of the version, does not automatically cause the filter pack files to be registered to index the affected document types by Exchange server! After surveying several of my customer's Exchange servers, I determined that the set of documents that would be indexed by Exchange is dependent on what was being indexed by earlier versions of Exchange.
Therefore, after installing the filter pack, you still need to Make This Happen (tm) - i.e., ensure that the filter packs are registered.
For Exchange 2010, the official Microsoft document is Register Filter Pack IFilters with Exchange 2010. An improved version of the script has been created by Pat Richard, and is available here. Pat's version also handles the required registration for the Adobe PDF iFilter pack, if you have downloaded and installed it.
Until next time...
