Hello Everyone,

We want to put an email validation in agent desktop on contact workspace for contact primary email address as currently it allows email address like [email protected] or [email protected] so our requirement is we don't want to allow agents to put any numeric value at the end of the email address.

So currently we achieved this by putting JavaScript validation through Connect Desktop Integration (JavaScript API) 's onbeforesave() event and its working fine.

But is there any thing standard through which we can achieve this otherwise I have to add this JavaScript validation script on all contact worksapce assigned to different profile
