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.
Some wireless service providers have other requirements specific to their
service. For example, Yahoo! requires you to pay for a POP account in order to
download email messages from your Yahoo! account to your device. Check
with your service provider to see if any provider-specific requirements exist.
Service provider settings change frequently. If your email account was
working, but you are currently experiencing problems, check with your
service provider to see if any of the account settings have changed.
I Have Problems Sending and Receiving Email
Short periods of time when email is unavailable are common due to server
problems or poor wireless coverage. If you have problems sending or receiving
mail for an extended period of time, check with your ISP or email service provider
to verify that the service is working properly.
Auto Sync Is Not Working
If Auto Sync is occurring and you turn your device off or the connection to your
email service provider is disconnected, the Auto Sync fails.
I Have Problems Sending Email
If you are able to receive email messages but cannot send them, try these steps, in
turn:
Make sure your ISP or email provider allows you to access email on a wireless
device. Several providers, like Hotmail, do not offer this option at all; other
providers require an upgrade to access email on a wireless device.
