I have problems using my account

Occasionally you may experience problems using an email account after you set it up. If you followed the account setup procedure (see Set up email) and are experiencing problems using the account, verify that the account complies with your email provider’s requirements:

•Verify both your password and your username for your email account.

•If you changed your password in an online email account, you must change the password on your smartphone (see Change account login settings).

•Some wireless service providers require you to be on their network to use your email account. If this is the case, be sure to use your provider's network as the connection type for the account. If you’re connected to a Wi-Fi network, turn off Wi-Fi and try again (see Turn Wi-Fi on/off).

•Some wireless service providers have other requirements specific to their service. Check with your wireless service provider to find out whether any provider-specific requirements exist.

•If you’re trying to access a Yahoo! or Hotmail account, check with your wireless service provider to find out whether they support using your smartphone’s Email app to access free Yahoo! and Hotmail accounts. If your wireless service provider does not support this feature, you have the following options:

•Upgrade your free accounts to a Yahoo! Mail Plus or Hotmail Plus account. These versions of Yahoo! and Hotmail allow POP email access for mail clients, such as the Email app on your webOS
