The purpose of this post is to document the optimal Internet Explorer settings for good Microsoft Dynamics CRM performance. Even if you use Chrome or Firefox, if you use CRM for Outlook, you are still using Internet Explorer when you view CRM records.



  

  • Set Internet Explorer to default settings. Go toolsàInternet OptionsàAdvancedàReset. Dynamics CRM is tested using default Internet Explorer settings.

 

 

  • Turn off pop-up blocker or disable it for the CRM website

 

  • If using Internet Explorer 11, ensure that you install Update Rollup 2 for Microsoft Dynamics CRM 2013 and Update Rollup 17 for Microsoft Dynamics CRM 2011. These Update Rollups add support for Internet Explorer so you no longer need to add the CRM URL to Internet Explorer compatibility mode.  
  • If using Microsoft Dynamics CRM On premises, add CRM URL to Intranet Zone 
  • Disable third-party toolbars, such as Google or Yahoo, as these will also include pop-up blockers and script components that can interfere with CRM 
  • Turn off unnecessary third party browser add-ons
  • Close any browser toolbars, such as the Yahoo, Bing, or Google toolbars. These toolbars include popup blockers and can also scan scripts, causing issues with CRM.
  • Configure Internet Explorer to download more than two files at a time.

     

  • Increase amount of space used for temporary internet files. Click ToolsàInternet Options. On general tab, click “settings” in the “Browsing History” section. Increase disk space to use to 350.
