How does FYI determine the Owner of an email?

The Owner is dependent on where the email has been created.

Email is created in FYI

When an email has been created in FYI, the Owner field will be set as the FYI user who created the original email. 

Email is created in Outlook

When an email has been created in Outlook, the Owner is dependent on how many FYI users are the recipients of the email:

• Where the email has been created by one FYI user, they will be set as the Owner of the email.
• Where there are multiple FYI users as the recipient, the Owner will be matched to the user in FYI following the priority order: From, To and CC.
