Configure Gzip Compression Settings

Applies to: Exchange Server 2010

Topic Last Modified: 2011-03-19

You can use the Shell to configure Gzip compression for Microsoft Office Outlook Web App in Microsoft Exchange Server 2010. 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.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Outlook Web App virtual directories" entry in the Client Access Permissions topic.

This example configures Gzip compression to High on an Outlook Web App virtual directory that's named owa in the default Internet Information Services (IIS) Web site on the local server.

Set-OwaVirtualDirectory -identity "owa (Default Web Site)" -GzipLevel High

This example sets Gzip compression to Off on an Outlook Web App virtual directory that's named owa in the default IIS Web site on the local server.

Set-OwaVirtualDirectory -identity "owa (Default Web Site)" -GzipLevel Off
