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).

OS X iServices Trojan Horse

February 2, 2009

cautionAn Intego Security Alert, published January 26, announced the discovery of a new variant of the Mac Trojan Horse iServices virus. The trojan is being packaged in cracked versions of Adobe Photoshop CS4 found on torrent sites.

Running the patching application to apply the crack will execute the trojan, which listens for web requests makes repeated connections to several IP addresses.

It’s important to recognize that this is NOT a proof-of-concept virus – this is the real thing. The previous version of the trojan used infected computers in DDoS attacks on a number of websites.

Intego claims that VirusBarrier X4 & X5 with the latest virus definition files will protect against this trojan. SecureMac, a mac-focused security site, has released the iServices Trojan Removal Tool (download connects to SecureMac’s download link), which they claim will also remove infected files.

The best defense against the virus, as well as it’s predecessor (bundled with a torrent of iWork ’09), is obviously to avoid downloading & installing cracked or otherwise modified software – whether from torrent sites or via peer-2-peer networks. Investing in appropriate anti-virus software is obviously (increasingly) important, as well.

Sigh. It was bound to happen sooner or later. Apple’s historic viral immunity really was just a question of market-share, after all…
