iPhone Email Attachments: PDF, Word Doc and Spreadsheets
All email attachments work the same on iPhone, but an example for each kind of attachment will be shown to help the users who are new to emailing on iPhone.
Open PDF on iPhone
Find the email that has the PDF attachment on your iPhone and open it. Attachments will show up in the checkered outline box with a download arrow (as shown below).
Press inside the box to download the attachment to the iPhone. When the PDF document is ready to be opened, the checkered box will turn into a solid box with an arrow pointing right (as shown below).
Press inside the solid box to open the attachment viewing screen. Swipe up or down to scroll through the pages, or use two fingers to zoom in and out.
Open Word Document or Spreadsheet on iPhone
A Word document and/or spreadsheet attachment can be opened on iPhone in the same way that a PDF file can. Find and open the email with the attachment, press the arrow in the dotted box to download and wait for the phone to load the Word document or spreadsheet. When the solid box appears, press the box again to open the document in the attachment viewing screen. Don't forget that you can zoom in by expanding the screen with two fingers. See examples below for how your iPhone email attachments will look when opened from your phone.
