The investigators will recruit from Veterans at the study sites who have uncontrolled glucose (HbA1c >= 9%) and have not used the patient portal. Participants will be randomized to one of two conditions: 1) Encouragement and 2) Comparison. Participants randomized to the encouragement arm will receive a mailing to emphasize the importance of setting health goals and explain how MHV can help and will have the opportunity to participate in the Supported Adoption intervention. Those in the intervention will receive a one-on one session (to sign up and learn how to use secure messaging), a group training session (which will emphasize the features most meaningful for diabetes management) , and follow-up support after the training sessions to to provide further encouragement. Those in the comparison condition will receive a mailing with only the goal setting content (no MHV nor intervention component offer).
