Issue Solution: Regretfully, there is no Save option available anywhere in OWA.
However, Microsoft has two possible solutions for this issue:
1. Within OWA:
a. Open the email in question
b. Click anywhere in the body of the email.
c. Hold <ctrl> and hit S. This will open the Save window.
d. Keep the filename offered, or the email file will not open.
e. Choose the folder in which you wish to save the email.
f. Click Save
g. The email is saved as web-file (MHTML Document).
h. You will not be able to reopen the file unless you are logged into your OWA account, so I believe it may defeat the purpose of saving the file to your desktop in the first place.
2. You can use an email client, such as Outlook, to connect to your Office 365 account.
a. You can download and install a free trial of Office 2013 Professional Plus, which includes Outlook 2013 by following the instructions in this article: http://community.office365.com/en-us/wikis/upgrade/4177.aspx
b. From the client, you can save email messages to your desktop, or to any folder.
c. These saved files can then be reopened through the client, even when working offline.
Sad, but true. Unfortunately, for our client we had to go back to Outlook 2003 and configure as a POP account so they could save mail messages as text files to their file server.
