Because i never dealt with ssl's other then installing them. Would it be easier for me to create a new certficate or update the old. This issue is causing huge problems for me.

Hosted Exchange uses RPC over HTTPS protocol to connect through a proxy server. The proxy server provides a certificate to protect your connection. If Outlook fails to validate the certificate it won’t be able to connect and will display the following error: BrowserSafeguard and other software that is used to capture HTTPS traffic can replace the Exchange proxy server which makes certificate validation impossible. In this case Outlook will not connect unless the software is disabled or removed. You simply need to removethe application to fix the error. How Do I Find and Remove It? Remove the application Go to Start > Control Panel > Programs and Features. Find BrowserSafeguard or RocketTab or Wagamor What Other Programs Cause Certificate Error? > Click Uninstall/Change. Remove any existing certificates If the issue persists after BrowserSafeguard is removed: Go to Start > Run > Type certmgr.msc> Click OK.

There is a number of ways to avoid installing the software: Install an anti-virus and keep it up-to-date. During installation of free software pay attention to everything you see in the installation wizard. Choose Custom installation option instead of Standard or Quick/Express to make sure you install only the things you need. Never install software through so-called installers. There is always a way to directly download freeware applications from their publishers’ websites. What is BrowserSafeguard? BrowserSafeguard is an applicationthat is designed to protect your Internet connection. Though the purpose appears to be legitimate there are certain drawbacks of the application that make it a lot less useful: Installs a Trusted Root certificate(as DO_NOT_TRUST_FiddlerRoot)The certificate is used for HTTPS traffic interception. If it is installed you may encounter website access issues using HTTPS.Here is an examp
