Select the mailboxes as described below, and then specify other settings of the protection plan as appropriate.
To select Exchange Online mailboxes
Click Microsoft Office 365.
If multiple Office 365 organizations were added to the Cyber Protection service, select the organization whose users' data you want to back up. Otherwise, skip this step.
Do one of the following:
To back up the mailboxes of all users and all shared mailboxes (including mailboxes that will be created in the future), expand the Users node, select All users, and then click Group backup.
To back up individual user or shared mailboxes, expand the Users node, select All users, select the users whose mailboxes you want to back up, and then click Backup.
To back up all group mailboxes (including mailboxes of groups that will be created in the future), expand the Groups node, select All groups, and then click Group backup.
To back up individual group mailboxes, expand the Groups node, select All groups, select the groups whose mailboxes you want to back up, and then click Backup.
Note The cloud Agent for Office 365 uses an account with the appropriate rights to access a group mailbox. Thus, to back up a group mailbox, at least one of the group owners must be licensed Office 365 user with a mailbox. If the group is private or with hidden membership, the owner must also be a member of the group.
On the protection plan panel:
Ensure that the Office 365 mailboxes item is selected in What to back up.
If you do not want to backup the archive mailboxes, disable the Archive mailbox switch.
