The error message means that the login to their email account failed. The ID and PW would be the login information for their email account. If you are using Microsoft Exchange, the ID and PW would be their Windows login ID and PW. If you are using an external email account (like Earthlink, etc…) you should enter the login ID/PW for that account. This information is stored per MRM login, so if one user enters this, it doesn’t mean a different MRM user would be setup.
