How to View Zip Files in Outlook

By Amy Dombrower

A zip file is created when you create a compressed version of the file, reducing the file size and giving it a .zip file extension. Zipping files not only save hard-drive space but make it possible to email large attachments. Windows has a built-in zip utility called the Compressed (zipped) Folder feature, and there also are many commercial zip utilities you can use. The popular desktop email client Microsoft Outlook works well with these zip utilities, so you can zip or unzip a file attachment with little effort.

Things You'll Need

  • Microsoft Outlook

Step 1

Open Microsoft Outlook and log in to your email profile.

Step 2

Browse through your inbox. Double-click an email containing a zipped attachment you want to open.

Step 3

Double-click the attachment in the attachment field. The "Opening Mail Attachment" dialog box opens.

Step 4

Click "Open" to have Windows or your zip utility unzip (or extract) the file, revealing the original file. The file will open in your default program. For instance, if the unzipped attachment is a Word document, it will open in Word once it is unzipped.

Step 5

Save the document to your hard drive if you wish. If you just need to view it once, close the document.
