What type files can I attach to an email on my Lumia phone?

You can attach a picture from the Photos hub and Word, Excel, and PowerPoint files to an email. You can also share a video as an email attachment from the albums. To attach a document, it must be either stored on Office hub or attached to an email that you received. It is currently not possible to add the Office document to an email reply. You can attach a picture from any of yours photo albums, even you have not saved it to your phone. If you want to send more than one Office document or video, you will need a message for each attachment. You can attach multiple pictures to an email.
