Update details

A security vulnerability exits in the way that folder permissions are set in certain Microsoft Office 2011 for Mac 14.2 installations. This update resolves that vulnerability.

Improvements that are included in the update

The Office for Mac 2011 14.2.3 Update also includes the following improvements:

  • This update fixes an issue where some SkyDrive folders in Micorosft Document Connection are displayed as zero-byte files instead of folders.
  • This update provides critical updates for connection reliability with SkyDrive.

Improvements for Excel for Mac 2011

Improvements for Outlook for Mac 2011

  • This update fixes an issue where some IMAP users may receive an “Unknown namespace” error when they try to create special folders (such as Drafts and Sent Items) on the server.
  • This update fixes an issue with some IMAP configurations where Outlook repeatedly displays “Cannot create mailbox” errors.
  • This update fixes an issue that causes Outlook not to display details for certain contacts when Lync or Communicator is running.
  • This update fixes a problem that occurs when users reply to or forward Exchange email messages that were downloaded from Exchange 2007 servers. When this problem occurs, the Date field is missing from the body of the message.

    To correct email messages that have already been cached, right-click the folder that contains the email messages, select Folder Properties, and then then select Empty under Empty Cache. Or, you can delete the Exchange account and then add it again to resynchronize the account.

  • This update fixes an issue where users may have duplication of mail when they use Gmail and connect with Outlook by using IMAP.

    To adjust this setting, select Tools, select Accounts, and then select Advanced for the IMAP account. The setting defaults to synchronize all lMAP folders every two minutes.

  • This update fixes a connectivity issue that occurs when Outlook connects through a proxy server that uses NTLM based authentication.
