To add colleagues to your account, you must be a Yesware admin/account manager. To access the self-service portal, go to the Menu section of the Yesware Sidebar in O365 and select "Manage My Teams." Then, in the far left margin, click "Settings. From there, navigate to the "Users" section of the left-hand menu. In the upper right, there is an "Add Users" button. This button will allow you to fill empty licenses and/or purchase new licenses.
Please note that Yesware's subscriptions are per email address. If you are adding a new email address to your account, you'll be charged for an additional license. We'll confirm any additional charges prior to adding the new license.
If you'd like to add someone to your account, they must be on a verified domain. By default, verified domains will be the same domains associated with the Account Managers on your account. If you'd like to add a new verified domain, please use the "Send us a request" option in the top right section of this page to contact Support.
