Microsoft certifies the underlying cryptographic modules used in our cloud services with each new release of the Windows operating system:. Office service encryption includes an option to use customer-managed encryption keys that are stored in Azure Key Vault. For customer data in transit, all Office servers negotiate secure sessions using TLS by default with client machines to secure customer data.
For example, Office will negotiate secure sessions to Skype for Business, Outlook, and Outlook on the web, mobile clients, and web browsers. Skip to main content. This browser is no longer supported.

Microsoft servers use BitLocker to encrypt the disk drives containing customer content at the volume-level. The encryption provided by BitLocker protects customer content if there are lapses in other processes or controls for example, access control or recycling of hardware that could lead to unauthorized physical access to disks containing customer content.
In addition to volume-level encryption, Microsoft online services use Service Encryption at the application layer to encrypt customer content. Service Encryption provides rights protection and management features on top of strong encryption protection.
It also allows for separation between Windows operating systems and the customer data stored or processed by those operating systems.
Microsoft online services use strong transport protocols, such as TLS, to prevent unauthorized parties from eavesdropping on customer data while it moves over a network. Examples of data in transit include mail messages that are in the process of being delivered, conversations taking place in an online meeting, or files being replicated between datacenters. For Microsoft online services, data is considered 'in transit' whenever a user's device is communicating with a Microsoft server, or a Microsoft server is communicating with another server.
Strong encryption is only as secure as the keys used to encrypt data. It helps prevent sensitive information from being printed, forwarded, or copied by unauthorized people.
The message encryption helps ensure that only the intended recipient can open and read the message. A digital signature helps the recipient validate the identity of the sender. Both digital signatures and message encryption are made possible through the use of unique digital certificates that contain the keys for verifying digital signatures and encrypting or decrypting messages.
Recipients have to maintain their own private keys, which must remain secure. If a recipient's private keys are compromised, the recipient needs to get a new private key and redistribute public keys to all potential senders. OME: Encrypts messages sent to internal or external recipients.
Allows users to send encrypted messages to any email address, including Outlook. Mail, and Gmail. Allows you, as an admin, to customize the email viewing portal to reflect your organization's brand. Microsoft securely manages and stores the keys, so you don't have to. No special client side software is needed as long as the encrypted message sent as an HTML attachment can be opened in a browser. IRM: Uses encryption and usage restrictions to provide online and offline protection for email messages and attachments.
Gives you, as an admin, the ability to set up transport rules or Outlook protection rules to automatically apply IRM to select messages. Lets users manually apply templates in Outlook or Outlook on the web formerly known as Outlook Web App.
OME doesn't let you apply usage restrictions to messages. The maximum length is 64 characters, and the value must be unique in your organization. Organizational unit : Typically, the default location for the user account is the Users container.
To change it, click Browse and select the OU or container where you want to create the account. Don't use apostrophes ' or quotation marks ". Although these characters are allowed, they might cause problems later for example, assigning access permissions to the mailbox. If this value is different than the Alias value, the user's email address and account name will be different important if the email domain and the Active Directory domain are the same.
Require password change on next logon : Select this check box to force the user to change the initial password when they first sign in to the mailbox.
You can click Save to create the mailbox and the associated Active Directory user account, or you can click More options to configure the following additional settings:.
Mailbox database : Click Browse to select the mailbox database that holds the mailbox. Create an on-premises archive mailbox for this user : Select this check box to create an archive mailbox for the mailbox, and then click Browse to select the mailbox database that holds the archive mailbox.
Items are automatically moved from the primary mailbox to the archive based on the retention policy settings. For more information, see Address book policies in Exchange Server. This example creates a new mailbox and Active Directory user account for Pilar Pinilla with the following settings:. Name : Pilar Pinilla. This value is also used for the display name, because we aren't using the DisplayName parameter. The alias value is pilarp because we aren't using the Alias parameter, and pilarp is taken from the UserPrincipalName parameter value.
For detailed syntax and parameter information, see New-Mailbox.
