We have experienced a limitation within Service Desk 4.5 SP15.
A lot of our staff have two email addresses and depending on which site they are working at, will depend on which email address they use. However SD4.5 only allows one email address to be set within the person record. So they are unable to log a request automatically from one of their email addresses.
Is it possible to allow multiple email addresses to be set in a person record to rectify this issue?
I am led to beleive this is a feature of SD5 but at this point in time, an upgrade is not an option.
Keep in mind that if you use the function to create service calls from incoming email, you must have unique values in the email address field, which ovsd uses to respond to the email. This is the only way it can know who sent the mail and validate the sender against the person records (assuming you have configured the function for validation). If you need this function, check how it works before you start to try multiple email addresses for person.
