"Email Users" action not working

 

When your SharePoint website has many users and you try to email to them by using the "Email Users" action, you may be having some difficulties doing so.

We get error “Could not perform this operation”

Here is the details why it happens.

-There is a limit of 2048 characters for URI in IE. in case the length increases , the page wont popup us with error, it shall simply tries redirecting to same page

-In case, the length is within limit, it shall redirect to the page and  call JavaScript, which in turn shall invoke client email application.
