In order to keep Deskpro running smoothly and securely across cloud accounts, we have rules for how long we retain outgoing email logs.
Outgoing email logs can be viewed in Admin > Email > Email Accounts > Outgoing Email
Delivered outgoing emails are retained in the log for 60 days.
Outgoing emails with errors are retained in the log for 180 days.
Outgoing emails that are rejected are retained in the log for 15 days.
