Microsoft recently updated Entourage 2008, releasing the Entourage 2008 Web Services Edition update, a small but noteworthy update that moves Entourage’s feature set a few steps closer to Outlook. The Web Services update abandons WebDAV in favor of the Web Services protocol for all communication with Exchange servers.

According to Microsoft, Exchange Web Services offers a “more robust feature set” and supports an Out of Office Assistant, logging, and improved Autodiscover and synchronization services. Stability and compatibility between email clients is improved by shifting responsibilities from client applications to the server.

System Requirements:
  • Intel, PPC G5 or PPC G4 processor (500MHz & higher)
  • 512MB of RAM
  • OS X 10.4.9 or later
  • 1.5GB of free hard drive space
  • Microsoft Office SP2 (12.2.0) or higher
  • Microsoft Exchange Server 2007 SP1 with Connectivity to Update Rollup 4 or higher (Mailbox & Client Access servers)

NOTE: The Entourage 2008 Web Services Edition is NOT compatible with Microsoft Exchange Server 2003 or earlier. If access to earlier versions of Microsoft Exchange Server is required, do not apply the Entourage 2008 Web Services Edition update.

iphone_homeApple’s recently released iPhone OS 3.1 has caused headaches & more than a little confusion for some users with Microsoft Exchange accounts. While the OS 3.1 update improves security policy adherence for iPhones when connecting to Exchange Servers, it also has the unfortunate side effect of breaking security compatibility with pre-3GS iPhones & all but the most recent iPod touches. The end result: many iPhone users who upgraded to OS 3.1 suddenly fond they could no longer sync with any Exchange Servers!

Fortunately, the synchronization issue is limited to Exchange 2007 Servers running SP1 & above, & there is a work-around to re-enable synchronization. Unfortunately, the work-around requires either convincing Exchange administrators to create a security policy exception or rolling back to OS3.0 on the iPhone.

In order to re-enable Exchange syncing with pre-3GS iPhones, Exchange administrators will need to create an EAS policy exception that will allow connections to mobile devices that do not support device encryption (either globally or on a per-user basis).

If the creation of policy exceptions is not an option (& that will likely be the case more often than not) there are 2 options: 1) upgrade to iPhone 3GS or one of the latest 32GB or 64GB iPod touch models, or 2) rollback to OS 3.0 (what will undoubtedly be the most popular solution).

The easiest way to rollback to OS 3.0 is obviously to restore the phone from a recent backup using iTunes (you did create a backup before you upgraded your phone, didn’t you???). Apple has a support article detailing how to backup, update, & restore iPhones & iPods. In case of emergency (ie: no recent backups!) you can go to this site to download firmware for iPhones & iPods. [NOTE: This site is NOT supported by Apple in ANY way!!!)

Finally, Apple has also updated it’s Enterprise Deployment Guide for iPhones. If you’re a sys-admin involved in the deployment & management of iPhones &/or iPods in an enterprise environment, this doc is a must-read.

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.

entourage_mac_2008_iconWhen Entourage runs its Send & Receive routine, it copies data from the Exchange server to the local workstation. It’s not uncommon for this local cache to get corrupted, which typically results in erratic synchronization. The end result is users that don’t receive new emails or the emails they send never reach the recipient. Even more frustrating for users is that the problems are usually random – some mail comes & goes fine, some doesn’t. A critical clue is that when using the OWA web interface, there aren’t any problems sending or receiving mail.

Fortunately there’s an easy fix – clear the cache in Entourage. You can clear caches on specific folders, or for the entire account. The process deletes all the data that’s stored on the local workstation, then connects to the Exchange server & downloads everything from scratch. Think of it as a kind of reset button for the user’s Entourage account. Instructions for clearing the Entourage cache are below. If you’re interested in a little more info on the subject, check out this post. For instructions, read on.

Reseting the Exchange cache in Entourage

  • Right-click on the exchange identity (or sub-folder) & select Folder Properties


  • Under the General tab, click the Empty button in the section titled Empty Cache. NOTE: Any local items (calendar events, etc) that have NOT been synced with the Exchange server will be lost.


  • It may take some time to download all of the users data from the Exchange server. Be patient.

entourage_mac_2008_iconAccessing shared folders & calendars is one of the handiest features of Exchange services. Unfortunately, Entourage doesn’t handle shared folders quite as gracefully as some would like. When trying to access folders or calendars shared through MS Exchange accounts, it’s not uncommon to receive the following error:

The user’s folder could not be found. Entourage could not find a mailbox for the user User_Name

This error occurs even though the mailbox does exits & the user followed Microsoft’s directions to the letter – as found here.

There are a couple of potential causes for this error, but the most consistent workaround is to point Entourage directly to the URL of the shared calendar or folder rather than leaving Entourage to try & find the path itself.

Note: You may need to contact you system or exchange administrator to get the full URL of the calendar or folder in order to complete the steps below…

Use the full URL to open the shared calendar

  1. Click File, and then click Open Other User’s Folder.
  2. Click Find user.
  3. Click Advanced.
  4. Enter the user name & email address for the calendar you would like to access.
  5. Type the full URL to the user’s account and Exchange server.
    1. (The URL should be in the following format: https://exchange.<ServerName>.com/exchange/<EmailAddress> )
  6. Click OK.
  7. On the Type menu, click Calendar, and then click OK.
  8. It typically takes some time for the calendar to fully synchronize with the events on the server. Be patient.

More detailed information on this issue can be found in the following Microsoft knowledge base article (The article refers to Office 2004 but is still valid for Office 2008).

Microsoft posted a new update to their Office 2008 suite – version 12.1.4. This update is a fix for a bug created by the previous Office update (v12.1.3) which can prevent Entourage from sending & receiving meeting invitations.

The issue appears to occur most often with Identities that have both pop & exchange accounts configured & typically generates the following error:

“Unexpected Data was Encountered. Mail Could not be Sent.”

Error -17997

It seems that the 12.1.3 update broke a previously functional feature (namely, the ability to send & receive invitations from MS Exchange accounts). To Microsoft’s credit, they acknowledged the error & released a patch within (roughly) two weeks, which is not bad turnaround time. (We’ll leave the obvious question as to why they released another buggy update in the first place for another time…)

More information and the update itself can be found on Microsoft’s updates page.
