Configure Druva inSync to protect Public folder data

The availability of this feature may be limited based on the license type, region, and other criteria. To access this feature, contact your Druva Account Manager or Druva Support.

Before you begin

Before you initiate Druva inSync configuration to protect Public folder data, ensure that you have the following accounts created.

  • Microsoft 365 global administrator account with a valid Microsoft 365 license.

Log into inSync Management Console as a Druva inSync Cloud administrator and perform the following steps to set-up Druva inSync to protect Public folder.

Step 1: Provide Druva inSync permissions to access Public folders data

To protect and backup Public folder data, Druva inSync requires authorization from Microsoft 365. Also, the Druva inSync Cloud administrator must accept the required permissions to allow Druva inSync access to Public folder data. 

Druva inSync uses OAuth 2.0 to communicate with services like Microsoft 365. OAuth is an open protocol for token-based authentication and authorization on the internet. For more information on OAuth 2.0, see the OAuth website.


To establish the connection with Microsoft 365 and provide required permissions to Druva inSync:

  1. On the inSync Management Console menu bar, click Data Sources > Microsoft 365. Click Add Microsoft 365 Account.

  1. On the Microsoft 365 login page, enter the Microsoft 365 global administrator's user name and password for Microsoft 365, and then click Sign in
  2. Click Accept to grant inSync app the required permissions to access Public folder data. See Required permissions to access Public folders.

Step 2: Get data encryption key (ekey)

To ensure that the Microsoft 365 data that is backed up is secure, you must configure Druva inSync to get the data encryption key(ekey). 

 inSync requires access to the ekey to initiate the scheduled backup of any Microsoft 365 app data. The ekey is used to encrypt the data when it is being backed up to the inSync Cloud. This is part of the digital envelope encryption process that Druva strictly adheres to. Druva does not store ekey of the users and has no access to the data.

Use one of the following methods to enable Druva inSync to get the data encryption key(ekey):

Deploy inSync Connector 
At least one inSync Connector is configured and connected to the inSync Cloud (default option). For more information, see: 


  • inSync Connector acts as a Cloud Apps connector to provide the ekeys without requiring users to have their devices connected for the Cloud Apps backup .
  • If the registered inSync Connectors are not connected, backup of the configured Cloud Apps data fails.
  • inSync Connector does not need to have any domains or AD mappings added to it.
  • inSync generates a Not Connected alert if inSync Connector is not connected.

Enable Cloud Key Management 

If none of the earlier mentioned deployment options are used, you must have the Cloud Key Management feature enabled. For more information, see Configure Key Management for Cloud Apps.

Step 2: Configure Public folders for backup and restore

The settings that you define automatically applies to all subsequent auto-discovered Public folder. You can also change the settings of any auto-discovered Public folder. 

 You can configure Public folder for backup and download in the following ways:

2.1 Auto Configuration

2.2 Custom configuration

2.1 Auto Configuration of Public folders
