View & edit native Office files inside of Outlook
When using Outlook on the web you can click on an attachment such as Excel, Word, PDF, or an image and the file is displayed in a viewer next to the email message. It would be nice if this was done in Outlook for Mac as well. If I click on an attchement such as Excel it would open the Excel file in a native viewer in Outlook with the message beside it.
Using the same functions that are in the web version of Outlook.
