The Office 365 system caps individual email recipients at 500, regardless of user. This is an Office 365 limitation and not a UCCS limitation. However, with the Office 365 email system, you can create your own lists - termed 'distribution groups' in Office365, which allows you to add more than 500 recipients to an email.

The list of users must be provided and updated by the manager. OIT will not provide a list that is specific to a department, group, major, etc.
