When you are installing an Exchange 2013 server, or upgrading it with a cumulative update, you may encounter a warning message regarding the Office Filter Pack not being installed.


This computer requires the Microsoft Office Filter Packs – Version 2.0. Please install the software from…

This computer requires the Microsoft Office 2010 Filter Packs – Version 2.0 – Service Pack 1. Please install the software from…

These are warning messages and do not block the installation or upgrade of Exchange 2013. The Office Filter Pack is not a mandatory Exchange 2013 pre-requisite.

The Exchange 2013 pre-requisites page on TechNet, at the time of this writing, does include the Office Filter Packs as a step in the preparation of a server for Exchange 2013. What it doesn’t make clear is that they are not required.

The new Exchange Search already has support for indexing/searching Office file types, as well as a series of other file types including some third party formats such as PDF. You can see a full list here.

So should you install the Office Filter Pack? If you want to stop seeing that warning message, then yes. If you want to take the approach of only installing required software on your servers, then no. Consider also that installing it means potentially having to update it later on if there is a bug fix or a security issue.

    Hi Paul,

    Hope you are doing well.

    Though you have closed the forum just wanted to ask you a question.

    Our organization has exchange 2007 servers and they are planning to upgrade filter pack from 1.0 to 2.0 on few servers first and later on others. Is it okay if there is a mismatch in filter pack version???

    Does the version of the Office filter pack on Exchange 2010 have to match your Office version? Example, I’m running Exchange 2010 with Office 2010 filter pack 2 but on my desktop PC I’m running Office 2010 SP1.

        CU1 – setup would not let me proceed (via GUI either) so installed these and the Unified Communications Managed API

        Thanks for all your articles though – can you write one concerning the Monitoring mailboxes?
        After moving all mailboxes including the Arbitration mailboxes off the first database, I deleted the database. But then running “Get-Mailbox -Monitoring” produced errors saying the Health Mailbox “has been corrupted”
        They can be removed in ADUC but I cant find any articles on this

          Got the same issue with the healthmonitoring mailboxes after deleting the default database. Any clue to why this is happening?

    Hi Paul,

    Looks like the onenote and publisher file type has been included in CU1.
