Create a Template With the Account Selected

It is possible to create a template and choose one of your accounts as the sending account.

Begin by opening an Outlook form. If you use Word as your editor, you’ll need to open an Outlook form using Actions, New Mail Using, Microsoft Office Outlook (HTML) or disable Word as the editor in Tools, Options, Mail Format and re-enable it after you save the template.
Select the Account as usual.
Go to File, Save as menu and save it as an template (*.oft). By default, Outlook puts it in the Template folder, you may want to save it in My Documents or another location.
Close the email form (click No when asked to save it).

At this point, the template is ready to use.

Note: the following steps apply only to older versions of Outlook. Outlook 2007 and Outlook 2010 do not allow templates to be associated with toolbar buttons. In Outlook 2007, you need to open the template using the Forms menu, publish it to a folder, or copy it to an Outlook folder. See Tip 525: Using Templates

Go to Outlook’s View menu and select Toolbars, Customize.
Select the Commands tab and drag the Mail Message command to any toolbar or menu and then drop it.
Right click on the button you added and type a name in the Name field, change the Default style to Text, if desired, and change the Button image, if desired.
Finally, select Assign Hyperlink, then Open.
Browse to the location where you saved the template and select it.
Close the Customize dialog and click on the button you just added. Verify the correct account is selected, send a test message to your other account to verify it works.

More Information

When you select an account in a template, it uses the Account name to identify the selected account. If you remove the account or change the account name, the template will use the default sending account.
