Feature Comments and mitigation

Anti-spam agent management in the EMC

In Exchange 2010, when you enabled the anti-spam agents on a Hub Transport server, you could manage the anti-spam agents in the Exchange Management Console (EMC). In Exchange 2016, when you enable the anti-spam agents on a Mailbox server, you can't manage the agents using the EAC. You can only use the Shell. For information about how to enable the anti-spam agents on a Mailbox server, see Enable anti-spam functionality on Mailbox servers.

Connection Filtering agent on Hub Transport servers

In Exchange 2010, when you enabled the anti-spam agents on a Hub Transport server, the Attachment Filter agent was the only anti-spam agent that wasn't available. In Exchange 2016, when you enable the anti-spam agents on a Mailbox server, the Attachment Filter agent and the Connection Filtering agent aren't available. The Connection Filtering agent provides IP Allow List and IP Block List capabilities. For information about how to enable the anti-spam agents on a Mailbox server, see Enable anti-spam functionality on Mailbox servers.

noteNote:
The only way to enable the Connection Filtering agent is to install an Edge Transport server in the perimeter network. For more information, see Edge Transport servers.

 

Feature Comments and mitigation

Managed Folders

In Exchange 2010, you use managed folders for messaging retention management (MRM). In Exchange 2016, managed folders aren’t supported. You must use retention policies for MRM.

noteNote:
Cmdlets related to managed folders are still available. You can create managed folders, managed content settings and managed folder mailbox policies, and apply a managed folder mailbox policy to a user, but the MRM assistant skips processing of mailboxes that have a managed folder mailbox policy applied.

Port Managed Folder wizard

In Exchange 2010, you use the Port Managed Folder wizard to create retention tags based on managed folder and managed content settings. In Exchange 2016, the Exchange admin center doesn’t include this functionality. You can use the New-RetentionPolicyTag cmdlet with the ManagedFolderToUpgrade parameter to create a retention tag based on a managed folder.

 

Feature Comments and mitigation

Directory lookups using Automatic Speech Recognition (ASR)

In Exchange 2010, Outlook Voice Access users can use speech inputs using Automatic Speech Recognition (ASR) to search for users listed in the directory. Speech inputs could be also used in Outlook Voice Access to navigate menus, messages, and other options. However, even if an Outlook Voice Access user is able to use speech inputs, they have to use the telephone key pad to enter their PIN, and navigate personal options.

In Exchange 2016, authenticated and non-authenticated Outlook Voice Access users can’t search for users in the directory using speech inputs or ASR in any language. However, callers that call into an auto attendant can use speech inputs in multiple languages to navigate auto attendant menus and search for users in the directory.
