How long can I set the retention duration period?

By default, the retention period is 365 days. You can set the retention period either to a specific number of days (up to 10yrs or 3650 days) or choose ‘Retain forever’, if required.

‘Retain forever’ will never purge or delete the emails and can lead to storage requirements increasing over time. So, it is advisable to choose this option wisely.
