E-mails are not being saved to the Sent folder

Symptoms

When using an external SMTP client (such as Outlook) to send an email, the sent mail is not saved into the account's "Sent" folder on the server. They will not show up when looking at Webmail or through a different device.

Cause

When using Webmail to send an email, they are automatically saved to the "Sent" folder of an email account; however, external SMTP client will not have this configured by default, and messages will not be automatically copied unless the client is configured to do so.

Resolution

You will want to configure your remote email client to save mail to the Sent folder on the server. The option to do this would be Save copies of messages in the Sent Items folder or something similar in your remote email client's settings.
