If you are unable to use the ‘Email Link’ and other ‘Email’ functions within R365, it is often because your User Email Settings either need to be set up, or have been entered incorrectly. If emailing from R365 worked previously, you may have recently reset your email password.  You will need to update that password on your User Account to restore the email functionality.  Please note: if you have any auto-fill settings activated in your browser, you will need to deactivate auto-filling before updating your Email settings.
