Office 2008 Update & Exchange Web Services

June 14, 2009

entourage_mac_2008_iconWhile most of the blog coverage on the recent Office 2008 12.1.9 Update focused on the patching of Word vulnerabilities, considerably less attention was paid to what seems to me to be a much more important aspect of the update: Exchange Web Services support.

Entourage Web Services is Microsoft’s upcoming attempt to “achieve greater parity between Entourage and Outlook.”

According to Microsoft’s Description of the Microsoft Office 2008 for Mac 12.1.9 Update, this update is a “prerequisite for the installation of Microsoft Entourage 2008 for Mac Web Services Edition” and will have to be installed before the Entourage 2008 Web Services Edition can be installed.

Microsoft will be abandoning CalDAV for Exchange Web Services (EWS), which should offer better “performance, compatibility, and reliability” since EWS allows Entourage to shift the bulk of the ‘heavy lifting’ to the exchange server, rather than relying on the client to carry the load as it does now. It will also allow for the syncing of Tasks, Notes, and Categories with an Exchange server and will use EWS & HTTP to resolve names from the Global Address List, among other features.

Entourage for Exchange Web Services requires Exchange Server 2007 running Service Pack 1 with Update Rollup 4 or greater. Clients need to be running OS X 10.4.9 or later and the 12.1.9 update for Office 2008 for Mac, plus the Entourage for Exchange Web Services Edition (once released). More information on the Entourage for Exchange Web Services Edition can be found at The Office for Mac Team Blog.

Entourage Web Services is still in the beta stage, however, and not yet available to the general public. Its inclusion in the 12.1.9 update seems to imply that that may soon change.

Update to version 12.1.9 of Office update using the Auto-Update tool, or download the 12.1.9 update directly from Microsoft’s support site.

As with all software updates to mission critical software, please be careful.
