I am getting below error while loading email for in IE.  Same code, form is working fine in Chrome for email load. In fact the similar code is working is working fine on other entities.

FYI: I am on Dynamics 365 9.0.2 and not using Legacy form render.

How can I resolve it?

Sample code: 

if (typeof(po) == "undefined") {
    po = {
        __namespace: true
    };
}
if (typeof(po.Library) == "undefined") {
    po.Library = {
        __namespace: true
    };
}
if (typeof ($) === "undefined") {
    $ = parent.$;
    jQuery = parent.jQuery;
}
 
po.Library.Email = {
    LoadForm: function () {
// logic goes here.
}
    __namespace: true
};

    Please also check if you are passing parameter without single quote.

    CRM is expecting parameter to be in single quotes.

    This happens with us when we migrated from CRM 2011 to CRM 2016

    Never mind, I find the solution for this problem.  I was not a javascript error, it was not a syntax error. Just how IE is going to handle a syntax or function.

    I have one function on Onload or entity.  The way, this function was defined was defined was differnet.

    Let's say:

    if (typeof(po) == "undefined") {

       po = {

           __namespace: true

       };

    }

    if (typeof(po.Library) == "undefined") {

       po.Library = {

           __namespace: true

       };

    }

    if (typeof ($) === "undefined") {

       $ = parent.$;

       jQuery = parent.jQuery;

    }

    po.Library.Email = {

       LoadForm: function () {

           po.Library.Email.callFaultySignaturefunction(); // This will not work in IE, but work in Chrome and was causing issue.

           po.Library.Email.callfunctionwithCorrectSignature(); // This works fine.

    },

    callFaultySignaturefunction(){

    },

    callfunctionwithCorrectSignature : function()

    {

    },

       __namespace: true

    };
