This guide provides an overview of the Sync & Recover functionality available from the administration console.

Sync & Recover includes mailbox management tasks (e.g. managed folders and message stubbing). Stubbing / managed folders requires the use of the Mimecast Synchronization Engine. Mailbox synchronization and recover doesn't.

Introduction

 

 

Synchronization Task ListSync & Recover allows you to synchronize your users' mailbox folder structure, calendar content, and contacts from Exchange On-Premises or Office 365 (Exchange ) mailboxes with our archive. 

 

Once set up, synchronization starts automatically multiple times throughout the day. There is no exact synchronization timing, as each user's mailbox synchronization is balanced across that period. This prevents any undue server performance issues caused by everyone's mailbox being synchronized at once.

 

Once archived, a user's data is accessible to administrators with the appropriate permissions. They can:

  • View the content.
  • Browse and search folder structure.
  • Export and restore the content (if this functionality is enabled on your account).
  • Create a snapshot of a user's mailbox at a specific point in time, by configuring an existing sync task. This allows you to export or restore selected content, or download individual mailbox items from the snapshot. See the Sync & Recover: Creating Snapshots page for more information.
Whilst Sync & Recover is an administrator function, end users have access to archived email and familiar mailbox folder tree in one of the end user applications. They don't have access to calendar or contact items.

Prerequisites

 

  • A Mimecast Synchronization Engine Exchange Services installation is required to have calendars available for continuity purposes.
  • To manage a task's details, your logon must have permission to use the following menu items:

Requirements

 

To use Sync & Recover:

  • You must be archiving or retaining email for at least 58 days.
  • Legacy messages in your user mailboxes (e.g. those sent / received prior to archiving with us) must be archived with us.
    Speak to us if you have not yet ingested legacy data.
  • Create a Server Connection using Exchange 2010 SP1 or later.

 

Standalone Exchange Requirements

 

If you're using a standalone exchange, the following requirements apply. You must:

  • Allow inbound HTTPS access from us to your organization’s Client Access Server (/ews/exchange.asmx).
  • Share your master mailbox's credentials with the Application Impersonation management role with us.
  • Allow us to extract the folder tree and message metadata, by configuring impersonation rights to your organization's mailboxes. This requires you to provide us with the mailbox credentials of the user you wish us to use. See the Configuring Application Impersonation guide for your version of Exchange for full details.

 

Office 365 Requirements

 

If you're using Office 365, the following requirements apply. You must:

 

Using the Mimecast Synchronization Engine

 

If you're syncing and recovering using the Mimecast Synchronization Engine (MSE), you can upgrade to this method without impacting your existing archive folder views.

 

The steps to migrate are as follows:

  1. Create a Server Connection
  2. Create a new task with a test Sync & Recover group.
  3. Move some test users from an MSE tasks group to the new test Sync & Recover group.
  4. Once you have completed testing and are ready to migrate:
    1. Create Sync & Recover tasks for each group.
    2. Disable the old MSE tasks.

 

Considerations

 

During the migration process, consider the following:

  • The first time a user is migrated to Sync & Recover, the service synchronizes the metadata of all messages and folders in the mailbox. When multiple test jobs run and the user opens the same mailbox, the second job fails as the mailbox will be locked. It's recommended to break up synchronization tasks into multiple groups to prevent this.
  • When a user is switched from mailbox folder replication using the Mimecast Synchronization Engine, there is no rollback path.
  • You don't have to migrate all users at once, but any data submissions from the Mimecast Synchronization Engine for a migrated user are ignored. 
  • If you're introducing a Hybrid solution with Office 365, ensure the MSE user can authenticate against it and has the appropriate permissions. See the following resources for further information:

  • Sync & Recover will back up the calendar and make it available for restores. Howeverthe calendar won't be available during continuity mode in the Mimecast Personal Portal. The calendar would still be available in Outlook if the application runs, but if there's a need to keep the Calendar in Mimecast Personal Portal, you must continue running the calendar tasks in Mimecast Synchronization Engine.
