In Exchange Server 2013, you can use retention policies or managed folders for messaging records management (MRM). Only users running Microsoft Outlook 2010 and later have access to all client features for retention policies. However, retention policies are applied on the Mailbox server by the Managed Folder Assistant, regardless of the Outlook client version used by the user. Older Outlook clients do not expose the MRM functionality of these features. For example, because Outlook 2007 does not support retention policies, users can't apply personal tags to items or folders.

You can block users who are running older versions of Outlook from accessing their Exchange mailboxes. You can also block access on a per-mailbox or on a per-Client Access server basis.

For other management tasks related to MRM, see Messaging Records Management Procedures.

Note:
Before making any changes, note that hotfixes and service pack releases may affect the client version string. Be careful when you restrict client access because server-side Exchange components must also use MAPI to log on. Some components report their client version as the component name (such as SMTP or OLE DB), while others report the Exchange build number (such as 6.0.4712.0). For this reason, avoid restricting clients that have version numbers that start with 6.<x.x.>. For example, to prevent MAPI access completely, instead of specifying 0.0.0-6.5535.65535.65535, specify the two ranges so that the server components can log on. For example, specify the following: 0.0.0-5.9.9; 7.0.0-.

After you perform these procedures, be aware that when users are blocked from accessing their mailboxes, they will receive the following warning message.

Your Exchange Server administrator has blocked the version of Outlook that you are using. Contact your administrator for assistance.

To bypass the warning that MRM features aren't supported for e-mail clients running versions of Outlook earlier than Outlook 2010, you can use the ManagedFolderMailboxPolicyAllowed parameter of the New-Mailbox, Enable-Mailbox, and Set-Mailbox cmdlets in the Shell. When a managed folder mailbox policy is assigned to a mailbox by using the ManagedFolderMailboxPolicy parameter, the warning appears by default unless you use the ManagedFolderMailboxPolicyAllowed parameter.

What do you want to do?

Block versions of Outlook on a per-mailbox basis

You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "User mailboxes" entry in the Recipients Permissions topic.

This example blocks all Outlook versions earlier than 11.8010.8036.

Copy Code 
Set-CASMailbox -Identity adam@contoso.com -MAPIBlockOutlookVersions "-11.8010.8036"

This example restores access to a mailbox that's blocked by a version of Outlook.

Copy Code 
Set-CASMailbox -Identity adam@contoso.com -MAPIBlockOutlookVersions $null

For detailed syntax and parameter information, see Set-CASMailbox.

Block Outlook versions on a Client Access server

You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "RPC Client Access settings" entry in the Clients and Mobile Devices Permissions topic.

This example blocks Outlook clients prior to version 12.0.0 from accessing the mailbox on an Exchange 2010 or later Client Access server.

Important:
The value used for the BlockedClientVersions parameter in this command is an example. You must determine the correct client version numbers. You can use the Get-LogonStatistics cmdlet to retrieve the versions of MAPI clients that are connected to the mailbox database.
Copy Code 
Set-RpcClientAccess -Server CAS01 -BlockedClientVersions "0.0.0-5.65535.65535;7.0.0;8.02.4-11.65535.65535"

For detailed syntax and parameter definition, see Set-RpcClientAccess.
