There are a number of things you can change in your profile yourself, including your name, phone numbers, and DMS ID.
Note: Depending on the desktop UI version you have, the steps to edit your profile may vary.
To start, simply click on either your initials, or the blue question mark icon in the top right corner of the desktop application, and then click on User Profile.
Here you can modify your First Name, Last Name, Desk Phone, Cell Phone, or DMS ID.
Note: If you are adding or changing your cell phone number, you will need to click on Verify which will send a text message to the number entered, containing a code which you will enter to verify the phone number.
Once you are finished, click on Save.
