Sending, receiving, and organizing email in Outlook.com
Try these steps in order:
- On the iPhone, open Settings > Mail > Accounts.
- Select the email account that shows the wrong address.
- If this is the unwanted account, tap Remove Account.
- If the account is meant to stay but is asking for a password, open Settings > Mail > Accounts > [account] and tap Account Settings or the Password field, then enter the correct current password.
- Open the Mail app and check whether mail is syncing and whether messages can be sent and received.
If the account is an Outlook.com account and access is blocked, use the Sign-in Helper to start unblocking the account. If that does not work, use the When you can't sign in to your Microsoft account flow.
If the mailbox or OneDrive storage is full, Outlook.com may not send or receive email until space is cleared.
