outlook connections as Unknown

[Eyal_Solomon]

I`m using Fortigate 110C fw v5. When I look at the Top Applications Widget i see that my top application is Unknown. if i drill down into it I see that most connections are Outlook' s apps connection to Microsoft servers (we subscribers in 365). Is there a way I can set the application of these connections So that they will be identified as outlook connections?
