Exchange Server 2013 Gotchas

exchange.png-550x0Всем привет!

Ниже представлена сводная информация по основным отличиям Exchange 2013 от Exchange 2010.

Источник: Exchange Server 2013 Gotchas



  • Help -> About is gone

  • It’s very slow.

  • No S/MIME support

  • No Public Folder support, either for legacy public folders or modern public folders.

  • No distribution list moderation

  • No way to move the reading pane

  • Built-in spell-check is gone. IE 10 provides spell-check natively, but earlier versions of IE do not. A third-party add-in or an alternate browser is required.

  • Other things are gone; don’t waste too much time looking for them.


Client Connectivity

  • No BES support

  • …on a related note (and likely the primary reason BES is not yet available), the CDO/MAPI download is not yet available for Exchange 2013.

  • Outlook 2003 is no longer supported.

  • Direct MAPI access to the Exchange server is no longer supported.  RPC/HTTP (Outlook Anywhere) is required.

  • Outlook now reports that the server is it connected to is <<guid>>@<<active-directory-domain>>. This is intentional, if misguided.


Installation and Architecture

  • Cannot uninstall individual roles from a server, must uninstall all of Exchange

  • Install is painfully slow

  • The Hub Transport role is gone. There is now a Front End Transport service on CAS servers and Mailbox Transport services on Mailbox servers.

  • The Unified Messaging role is gone. There is a now a Unified Messaging Call Router service on CAS servers and a Unified Messaging service on Mailbox servers.

  • The CAS consists of three pieces: CAFE’ (Client Access Front End), which proxies all end-user protocols to the appropriate mailbox server (completing the decoupling of the MAPI endpoint started in Exchange 2010) and handles Outlook Web App; FET (Front End Transport) which proxies SMTP protocols to the mailbox server and is responsible for TLS setup; and Unified Messaging Call Router.

  • After an installation or an upgrade, services not starting is an endemic problem. You will likely need to increase ServicesPipeTimeout on your Exchange servers.

  • Documentation is minimal at best

  • Deployment and sizing guidance is non-existent.

  • Cannot be installed along with Exchange 2007 or Exchange 2010

  • Exchange 2013 Edge server is not available

  • Forefront Protection for Exchange is gone

  • For both Exchange 2010 and Exchange 2013, applying updates can often screw up the winrm configuration. If you get errors in EMS or EAC regarding «The WS-Management service cannot process the request», try this first:
      winrm quickconfig

  • Since you cannot interop with legacy public folders in RTM, if you need an Organizational Forms Library, you must create it yourself. To create an Organizational Forms Library:
      1. Create «Organizational Forms Library» folder under the Eforms Registry:
          New-publicfolder «Organizational Forms Library» -path «\non_ipm_subtree\Eforms Registry»
      2. Set the locale ID for the Org Forms Library:
      Set-PublicFolder «\non_ipm_subtree\Eforms Registry\Organizational Forms Library» -EformsLocaleID EN-US
    It is no longer necessary to set the PR_URL_NAME property.


Exchange Management

  • The Exchange Management Console is gone as is the Exchange Control Panel. They are mainly replaced by the Exchange Administration Center (EAC); which is completely web based.

  • If you are attempting to use EAC with IE 10, you need KB2761465 (released on December 11, 2012).

  • The Exchange Best Practices analyzer is no more.

  • The Exchange Mail Flow Troubleshooter is no more.

  • The Exchange Performance Troubleshooter is no more.

  • The Exchange Routing Log Viewer is no more.

  • The EAC does not provide a preview (or an after-view for that matter) of the PowerShell it executed.

  • Antispam and antimalware is crippled compared to earlier releases
      The E15 AV does not offer a quarantine
      The E15 AS does offer a quarantine (for the administrator, not per-user)

  • Antispam cannot be managed from the Exchange Administration Center; it must be managed using PowerShell in the Exchange Management Shell

  • Kerberos Constrained Delegation (KCD) is not supported for OWA

  • This isn’t new, but should be reinforced: DO NOT TURN OFF IPV6. Microsoft does not perform any testing to determine the effects of disabling IPv6. Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. See

  • System Center Data Protection Manager (DPM) version required for backups of Exchange 2013 is SC DPM 2012 SP1


Mailboxes and Databases

  • Mailbox sizes MAY appear to increase substantially when moving a mailbox to an Exchange 2013 mailbox server. In Exchange 2010 and before, only select properties of a particular mailbox item were assigned as part of the mailboxes diskspace allocation, causing under-reporting. Now, all item properties for a particular mailbox item are assigned to the mailboxes disk space allocation. However, some items in Exchange 2013 are now compressed which were not before. This can lead to a reduction in reported and allocated diskspace. So, prediction is basically impossible. Just be aware that it may happen.

  • Corrupt PropertyTags during a mailbox move are common. Using (Get-MoveRequestStatistics -IncludeReport <<alias-name>>).Report.Failures you can find the rule or message that is causing the problem and remove it.

  • Changes made to improve Office 365 and hybrid deployments had an unintended consequence (this is my conclusion). When you are performing impersonation (e.g., to open a different user’s mailbox via EWS), you should always impersonate using the email address.

  • As a corollary, it is recommended that the account UPN match the primary email address.

  • In a change that you won’t know about until you need to know it — MRS Proxy is not enabled by default in Exchange 2013. Use Set-WebServicesVirtualDirectory to enable it.

  • Clean-MailboxDatabase is gone
      Update-StoreMailboxState is designed to replace it
      Requires that you know the guid of the deleted mailbox
      No on-premises cmdlets allow you to find those out!

  • Get-LogonStatistics is non-operational. The cmdlet is still present, but it doesn’t work.

  • Exchange 2013 Enterprise Edition supports only 50 mailbox databases instead of the 100 supported in Exchange 2010

  • MRM 1.0 (Messaging Record Management — Managed Folders) is non-operational on Exchange 2013 mailbox servers. The cmdlets are still present, and will affect down-level servers (which you can’t use right now), but they don’t work with Exchange 2013 servers.

  • Moving mailboxes using the migration wizard in EAC can generate large amounts of log files for the database which hosts the arbitration mailbox. Use New-MoveRequest instead.

  • In a positive change, Office Filter Packs are no longer required. There is a new search technology used in all Wave 15 (Office 2013) products and it knows how to search all the Office file formats. This also includes the PDF format, so a separate iFilter installation for PDF is no longer required.

  • When using Database Availability Groups (DAGs) on Windows Server 2012, you must manually create the Cluster Network Object (CNO) and provision the CNO by assigning permissions to it.

  • While Windows Server 2012 provides support for large sectors (4 KB), Exchange 2013 does not support large sectors. Emulation of large sectors (512 E) is supported provided that all database copies are on 512 E.

  • The above statement is, in general, true. Additional capabilities of Windows Server 2012 are not supported by Exchange Server 2013. This specifically includes but is not limited to Hyper-V Replica.
