Microsoft Outlook is primarily used for the purpose of sending and receiving emails. However, sometimes Outlook experiences problems in sending emails. This can be quite annoying for the users as it stops their outgoing emails and causes their outbox folder to become bloated. If you are experiencing Outlook Express mail sending problems, then there is no need to worry as there are various options available for solving this issue.

Has your Inbox folder been left behind by your Outbox folder in terms of size growth? Have you been receiving error messages from Outlook like “Requested tasks can’t be processed because of the occurrence of some errors” or “Unable to open Outbox folder messages.”? Is Outlook Express sending out various copies of the same outgoing mail?

The reason for the display of these errors can be issues with the Outlook Express itself. For instance, a corrupted Outbox folder can be the factor behind the generation of these errors. Configuration issues like port changes executed by the email provider which haven’t been announced in advance can also cause these errors to occur.
