Archiving improved by providing larger mailbox architecture, simple migration of PSTs back to server, discovery options, retention policies and legal hold.
Large mailbox Architecture – maintains performance and provides option for DAS-SATA storage to reduce costs

If the archiving option sin enabled for a user, a new Mailbox will be created to the user name archive in which the user can set retention policies to move the mails to archive mailbox or the admin can set retention policies for the user mailbox.
Archiving simplifies discovery, retention and legal hold

5. What are retention policies? And what we can do with retention policies in Exchange Server 2010?
Retention policy is an option to move/ delete certain mails by applying rules. We can set retention policies at Item or Folder level. Policies can be applied directly within e-mail.

We can configure delete policy to delete the mail after certain period and Archive policies to move certain mails with the certain period to archive mailbox

6. What are the Retention Policies in Exchange Server 2010?
1. Move Policy – automatically moves messages to the messages to the archive Mailbox with the options of 6 months, 1 year, 2 years, 5 years and never – 2 years is default. Move mailbox policies helps keep mailbox under quota. This works like outlook Auto Archive without creating PSTs

6. Explain the federation commands in Exchange server 2010?
Establish federation trust = New-federation Trust
· Install signing certificate on CAS servers

Prove domain ownership = domainname.com IN TXT AppId = xxxxxxxx

Add-federatedDomain
· Must be accepted domain

7. How to establish federated sharing in Exchange Server 2010?
1. Create trust with certificate exchange
2. Prove domain ownership
3. Add domains

8. What is Microsoft Federation Gateway?
Exchange Server 2010 uses Microsoft Federation Gateway (MFG), an identity service that runs in the cloud, as the trust broker. Exchange organizations wanting to use Federation establish a Federation Trust with MFG, allowing it to become a federation partner to the Exchange organization. The trust allows users authenticated by Active Directory , known as the identity provider (IP), to be issued Security Assertion Markup Language (SAML) delegation tokens by MFG. The delegation tokens allow users from one federated organization to be trusted by another federated organization. With MFG acting as the trust broker, organizations are not required to establish multiple individual trust relationships with other organizations. Users can access external resources using a single sign-on (SSO) experience

9. What is Federation Trust?
A Federation Trust is established between an Exchange organization and MFG by exchanging the organization’s certificate with MFG, and retrieving MFG’s certificate and federation metadata. The certificate is used for encrypting tokens

10. What is Sharing Policy?
Sharing policies allow you to control how users in your organization can share calendar and contact information with users outside the organization. To provision recipients to use a particular sharing policy
Prerequisites to create a Sharing Policy
 A federation trust has been created between your Exchange 2010 organization and Microsoft Federation Gateway, and the Federated Organization Identifier is configured.
 Although you can create a sharing policy for any external domain, recipients from the specified domain can access your users’ information only if they have a mailbox in an Exchange 2010 organization and their domain is federated
