Try Microsoft Edge
A fast and secure browser that's designed for Windows 10
Every time the user tries to open a contact in outlook/crm, he get the pop up blocker error. I've already tried several MSFIXIT's and uninstalling other browsers, as well as re-registering .dlls. Originally the fixit's wouldn't even open in IE, they just opened a new blank tab, but I opened a fixit in chrome to fix that.
Can you try below steps and let us know the results ?In Internet Explorer, click on Tools | Pop-up Blocker | Pop-up Blocker settings | Add CRM URLIf above steps do not help us than can you share screenshot of the prompt here. Does prompt still appear if you disable CRM add-in from outlook ?
Do you have a Toolbar in your nav? turn it off and check out.
Maybe thats would help.
