This topic explains how to use the Exchange Management Shell to configure Gzip compression for Microsoft Office Outlook Web Access in Microsoft Exchange Server 2007. Gzip compression improves performance over slow network connections by compressing content on the server. Gzip compression might slow performance on the server.

By default, Gzip compression is set to low on all virtual directories.

  Procedure
  To use the Exchange Management Shell to configure Gzip compression
  • Run the following command to configure Gzip compression to High on an Outlook Web Access virtual directory that is named owain the default Internet Information Services (IIS) Web site on the local server:
Set-OwaVirtualDirectory -identity "owa (Default Web Site)" -GzipLevel High
  • Run the following command to set Gzip compression to Off on an Outlook Web Access virtual directory that is named owa in the default IIS Web site on the local server:
Set-OwaVirtualDirectory -identity "owa (Default Web Site)" -GzipLevel Off

You must restart Internet Information Services (IIS) by using the command iisrest/noforce for these changes to take effect.
