You can't send an e-mail on a Windows Mobile 6.1 device

Note This article applies to Windows Mobile 6.1.
Your Windows Mobile 6.1 phone, that is enabled to use a POP3 or IMAP e-mail account unexpectedly stops sending e-mail, and the e-mail messages may stay in the Outbox folder after you synchronize. You may also receive the following error when you try to send e-mail.
The message cannot be sent
Even though you can't send e-mail messages, you continue to receive incoming e-mail messages.

Note This does not happen for a Microsoft Exchange Server e-mail account.
This behavior happens because the e-mail account details are corrupted when the Windows Mobile 6.1-based device does not connect to the SMTP server.

Note After you install this update, your Windows Mobile device will automatically restart to complete the installation.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
This behavior is associated with a feature that is introduced in Windows Mobile 6.1. The feature allows for mobile operators to specify an alternative SMTP server name that is used if e-mail messages cannot be sent by using the user-specified SMTP server name. If the mobile operator does not specify an alternative SMTP server name and if the Windows Mobile 6.1-based device does not connect, the e-mail account is corrupted and cannot send e-mail messages.
