This site is used by the Office Error Reporting feature. The following list of alternate sites should be added in case this site is overloaded):

http://watson3.microsoft.com - 207.68.166.191
http://watson4.microsoft.com - 207.68.166.192
http://watson5.microsoft.com - 207.68.166.193
http://officewatson.officeupdate.microsoft.com - 207.68.166.243

The majority of these sites have an IP address beginning with 207.68.166.xxx. Some of the sites listed above reside on the same IP address (for instance http://watson.microsoft.com and http://officewatson.officeupdate.microsoft.com). You could list access to sites by providing the IP address, but occasionally these URLs change and move to a different IP address, which may result in a broken link. It is suggested to use the URL name (http://address>), which is more likely to remain the same over time.

A simple solution for allowing access to Microsoft

A simple solution for enabling access to Office related Microsoft Web sites is to add the following information to your list of allowed Web sites using the administrative features of your proxy server:

*.microsoft.com

For port 80 or port 443.

Be sure to set your system to allow access to this URL for port 80 and port 443.

However, if you want users to access most of the sites in the above domain with the exception of Windows Update or Office Update, you face a bigger challenge, but it is possible. To block access to these update sites, you block the following URL names by using proxy server settings:

http://v3.windowsupdate.microsoft.com
http://v4.windowsupdate.microsoft.com
http://v5.windowsupdate.microsoft.com
http://windowsupdate.microsoft.com
http://update.microsoft.com
http://office.microsoft.com/officeupdate
