Email retention impact to your organization
NOTE: Salesforce Support can only search for attachments and emails sent up to 30 days in the past, our servers don't retain user activity beyond that time frame. Attachments sent as links exceeding 3Mb from a Salesforce org using the "Send an Email" button are stored for a 30-day period.
