Client logging in Outlook 2011

Brian Hadfield -

Outlook for Mac provides the option to turn on logging for certain features, such as the following:

  • Autodiscover service

  • Microsoft Exchange (folder and item synchronization)

  • Microsoft Exchange Calendar

  • LDAP transactions

The log file contains the following information:

  • Issues when sending or receiving e-mail messages, calendar items, notes, tasks, and meeting requests.

  • Type or severity of errors, if known.

The log file may also contain user information, including user name, sender and receiver’s e-mail addresses, and the contents of user’s e-mail messages, notes, tasks, calendar, and contacts. Microsoft does not use this information to contact users without their consent. If users are concerned that their data file contains sensitive or confidential information, they may review the contents of the data file by using text-editing software, and remove the information from the file before sending the data file to support professionals.

Turn on logging

To turn on logging
  1. On the Window menu, click Error Log.

  2. In the Errors window, click Settings  

  3. Select the Turn on logging for troubleshooting check box, and then click OK.

    • Data files that have the name Microsoft Outlook_Troubleshooting_0.log are written to the desktop.

    • Outlook does not include authentication information in the data files.

    • Outlook appends new log entries to the data file until the file is either moved or deleted.

Turn off logging for individual features

As described earlier, Outlook logs events for the following features: Autodiscover service, Exchange (folder and item synchronization), Exchange Calendar, and LDAP transactions between Outlook and Microsoft Exchange Server. If you are troubleshooting calendar issues, you can turn off logging for the other features in the /Users/username/Library/Preferences/ file. By default, this file is not generated. You must create this file and then set the value to false for the specific feature that you want to turn off. The following table lists the Outlook logging features and the command to disable logging for each feature. 

Featureplist file

Autodiscover service

In the Terminal window, type defaults write ~/Library/Preferences/ -dict enabled -bool false "detail level" -int 4

Exchange (folder and item synchronization)

In the Terminal window, type defaults write ~/Library/Preferences/ -dict enabled -bool false "detail level" -int 4

Exchange Calendar

In the Terminal window, type defaults write ~/Library/Preferences/ outlook.calendar -dict enabled -bool false "detail level" -int 4

LDAP transactions

In the Terminal window, type defaults write ~/Library/Preferences/ -dict enabled -bool false "detail level" -int 4

Setting the enabled flag to false for all the .plist entries will stop all logging operations.

View the log file

When you turn on logging in Outlook, a log file is created on the desktop. The log file opens in the Console and you can view it while Outlook is running. Each entry has a name that identifies the feature that is being logged. The following table lists the label for each feature.
