Removing an email account from your iPhone’s native email app is simple. Just follow the steps below.
- Open Settings
- Tap Accounts & Passwords
- Tap the Account you want to Delete
- Tap Delete Account (in red letters)
- When prompted “Are you sure?”, Tap Delete from my iPhone
All data which was being synced will not be removed from your phone. This includes Mail, Contacts, Calendars, Notes etc… Although this information will be removed from your phone, it will still remain on the email server. To get access to it again, simply add the account to your mobile and it will be copied back to your phone.
It’s also important to note that if you’re looking to just remove the Calendar, in Step 3 above, just mark the toggle from ON to OFF under the Calendar (or Notes etc…).
