"Unknown Email" and "This email is dated before your installation date" when opening emails in the In Tray
Issue
When opening certain emails in my In Tray, one of the following messages is displayed:
Unknown Email.
This email is dated before your installation date.
Cause
The emails are dated after the FYI trial started, but before the user first logged in to FYI, which means the Email AutoFile settings were not automatically applied.
These older emails will appear in users' In Trays once they have been opened or previewed in the user's Outlook, with the FYI Add-in pinned.
