If you find yourself typing the same text in many different emails, you can create a Quick Part that contains the text. The Quick Part can then be easily inserted into email messages when you need it.

In a blank email message, type the text that you want to add to Quick Parts.

Select the text, then click Quick Parts on the Ribbon, and select “Save Selection to Quick Part Gallery”. In the Building Block dialogue box, name the entry, type a description if desired and set any other options. Do NOT change the Gallery. Leave it as Quick Parts. Click OK when you are done.
