How GFI Archiver works with Microsoft 365

GFI Archiver with Microsoft 365 can be deployed in 2 ways:

  • Using a Mail flow - BCC the message to rule - GFI Archiver uses a dedicated mailbox configured in Microsoft 365 to act as a journaling mailbox. GFI Archiver archives all emails copied to this mailbox. This is possible by setting a forwarding rule on Exchange Online, to BCC all incoming and outgoing email to this mailbox. GFI Archiver connects to this mailbox to monitor new emails and transfer them to the archive store database. For more information refer to Setting up a Microsoft 365 Journaling Mailbox.
  • Using a Journaling rule and an external journal mailbox - Microsoft 365 also offers a native journaling facility, but this requires a non-Microsoft 365 email account as the journaling destination. This complicates the set-up when compared to the BCC rule as it involves a third party. This method is suggested when deploying GFI Archiver in a hybrid environment, for example where you have mailboxes both on Exchange and on Microsoft 365. For more information refer to Step 1: Setting up a 3rd Party Mailbox in Microsoft 365.

Using a Journaling rule and an external journal mailbox
