Reporting Outlook Client Versions Using Log Parser

I'm doing a little cross-pollination today. Chris Lehr, one of my colleagues at ExtraTeam, worked up a Log Parser script that produces a report showing all the clients versions connecting to Exchange.  This is very helpful to show which clients are running Office versions in your organization that should be updated prior to migration.  Check out his blog post here.

Outlook Client Version Report

Clients will always get the best experience using the latest version of Office, currently Office 2013 SP1. The best practice is to always update your clients with the latest cumulative update prior to migration. this is especially true when you're migrating to Office 365, since most updates pertain to Office 365, Exchange Online, and Exchange 2013 compatibility.

If you find that you need to upgrade clients to a new version of Office, I recommend that you install the x86 version of Office to provide the best compatibility with add-ons and third-party products. Some customers think they need to install Office x64 on Windows x64 operating systems, but that's not the case. See 64-bit editions of Office 2013 for details on when it makes sense to install Office x64.

If you're an Office 365 customer, I strongly recommend checking out using the Office 2013 ProPlus software deployment that's most likely part of your Enterprise license. This version of Office 2013 can be installed on up to 5 PCs, iPads, tablets, etc. and is always up-to-date since it's a cloud-managed service.
