We had earlier seen the steps for configuring email accounts such Yahoo, Outlook in an Android tablet. Now let us see the procedure for removing configured email accounts on Google Nexus 7.
Step 1: Tap the Settings icon on Android tablet.
Step 2: In the Settings screen, navigate to Accounts section and tap account you want to remove (IMAP etc..)
Step 3: Then tap and hold on email address to account detail screen.
Step 4: Tap the option icon available at the top right hand corner and select Remove account from the menu list.
You can repeat the same for Yahoo and Gmail accounts.
