If you’re a Exchange user on your iPhone, there are a few steps you can take to delete your account. First, open the Exchange app and sign in. Then, click on the three lines in the top left corner of the main screen and select “Delete Account.” Next, enter your name and password for your Exchange account. Click on the “Delete Account” button. You’ll be asked to confirm deletion before you can finish. Once deletion is complete, you’ll need to log out of Exchange and then back in to continue using your account.
