Overview

When the Calendar is being created, the Kerio Connect will send an automatic email.

Once the invitation is being accepted, the email is being automatically transferred to the user Trash folder.

Diagnosis

The Kerio Connect generates emails while sending Calendar invitations. The accept/maybe/decline actions trigger automatic Kerio Connect Delete function, that can be tracked in Operations logs.
