Mailstore Information: Archiving Microsoft Office 365 With Mailstore

Choosing the Right Archiving Strategy

Archiving All Incoming and Outgoing Emails Automatically

With this archiving method, all emails are archived before they are delivered to the user mailboxes.

Advantages

• Completeness of the archive is guaranteed
• Emails cannot be manipulated before archiving
• Meeting legal requirements is made possible or greatly facilitated

Disadvantages

• If private emails are allowed in the company, this archiving method may cause difficulties regarding the privacy laws of some countries. In this case, a company-wide ban of all private email communication, a contractual agreement with the employees or approval of an employee organization would be required
• The workload of the email server and the amount of data is not reduced because all emails are still delivered and stored in the mailboxes
• Emails can only be allocated to users as sent or received object; a reproduction of the mailbox folder structure is not possible

Requirements

• On-Premise Mailstore Server
• Your Office 365 plans must support a journal mailbox
• An external Mailbox for the journal mail to be sent (Office 365 places limits that require you to use a mailbox outside the Office 365 Organisation for Journalling)

Archiving of Individual Mailboxes

With this archiving method, emails are archived from the individual mailboxes of the users. This can be achieved by archiving the mailboxes directly from the email server or, if that is not possible, by archiving of email clients.

Advantages

• The folder structure of the archived mailboxes, email clients or PST files is applied to the archive facilitating access to the archived emails
• The archived emails can be deleted from the mailboxes according to pre-defined rules permanently reducing the workload of the email server

Disadvantages

• Emails can be deleted or manipulated before archiving, even if the archiving intervals are very short
• Meeting legal requirements cannot, or only with difficulty, be implemented

Requirements

• On-Premise Mailstore Server
• Your Office 365 Plan supports the ApplicationImpersonation feature.
