I am unable to add a new mailbox to this phone

Hey KatherineKennedy,

Thanks for asking Apple Support Communities about the issue you're having with the Mail app on your iPhone. If you're having trouble adding a new email account, these steps may help:

Add an email account to your iPhone, iPad, or iPod touch

Mail Settings Lookup

If instead you're trying to add a mailbox to an existing email account on your iPhone, these steps should help: Use mailboxes to organize email on your iPhone, iPad, or iPod touch

If we've misunderstood the issue, or you're still having trouble, let us know more details:

• Are you trying to add a new account or a mailbox to an existing account, and what happens when you try?
• Does an alert appear, and if so, what does it say?

The more details you can provide the better.

Take care!
