I have question. After adding my add-in to online outlook what auto adds emails from sidebar. Emails have extra naming in their names. For example: email: example@example.com
in cc field will be - example@example.com<example@example.com>

Question is why outlook added this extra <example@example.com> stuff to email? How to remove them if I am adding them by api calls?

I am using office.app.js in my add-in just in case

function _getMailItem() {
            return Office.context.mailbox.item;
 }

function addRecipientPortion(listName, emails) {
            var deferred = $q.defer();
            var mailItem = _getMailItem();
            var recipientList = mailItem[listName];

            recipientList.addAsync(emails.slice(0, 100), function (asyncResult) {
                if (asyncResult.error) {
                    deferred.reject(asyncResult.error);
                } else {
                    deferred.resolve();
                }
            })

            return deferred.promise;
        }

emails acording documentation must be array of string but if they are it rises error.

if emails are in this format it works fine but it did not work in desktop outlook
