The Microsoft® Exchange Server Analyzer Tool has determined that you are running one of the following types of third-party software:

• A third-party Microsoft Office Outlook® add-in, such as antivirus software or fax software

• A third-party application that accesses your Exchange server

• Third-party synchronization software for mobile devices

It is recommended that you investigate what types of third-party applications your users are running, and then decide whether you want to put restrictions on those applications or remove the applications completely. Remember that running third-party software can frequently cause excessive loads on your servers.
