.We know a lot of you have been waiting for this, and so it is with great excitement that we announce that Exchange Server 2013 RTM Cumulative Update 1 (CU1) has been released to the web and is available for immediate! This is the first release using the. In addition to this article, the Exchange 2013 RTM CU1 are also available.Note: Article links that may not have been available at the time of this post's publishing are now available. Updated, including Release Notes, is now available on TechNet.CU1 is the minimum version of Exchange 2013 required for on-premises coexistence with supported legacy Exchange Server versions. The final build number for CU1 is 15.0.620.29. For more information on coexistence, check out the documentation, and this covering deployment of and coexistence with Exchange Server 2013.
Today Microsoft released CU1 for Microsoft Exchange 2013. Cumulative Update 1 for Microsoft Exchange 2013 can be downloaded here: Exchange 2013 CU1 Download. Description of Cumulative Update 1 for Exchange Server 2013. CU1 for Microsoft Exchange 2013 is the last step for Exchange 2013 and Exchange 2010 SP3 coexistence. Hi Team, We have an exchange 2013 server with CU1 and we have to update it to CU12 or CU13. Do we have to update it first to CU4 for the SP1 or we can directly update it to CU12? We are planning for a Hybrid 2013 setup. Hope you can assist us on this. It is not necessary to install any Exchange Server 2013 Cumulative Updates or Service Packs released.
Upgrading/Deploying Cumulative Update 1Unlike previous versions, cumulative updates do not use the rollup infrastructure; cumulative updates are actually full builds of the product, meaning that when you want to deploy a new server, you simply use the latest cumulative update build available and do not necessarily need to apply additional Exchange Server updates. Active Directory PreparationPrior to upgrading or deploying the new build onto a server, you will need to update Active Directory. For those of you with a diverse Active Directory permissions model you will want to perform the following steps:. Exchange 2013 RTM CU1 includes schema changes.
Therefore, you will need to execute setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms. Exchange 2013 RTM CU1 includes enterprise Active Directory changes (e.g., RBAC roles have been updated to support new cmdlets and/or properties). Therefore, you will need to execute setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms. Exchange 2013 RTM CU1 includes changes to the permissions within the domain partition (e.g., Exchange Servers have been granted the ability to modify msExchActiveSyncDevices class on inetOrgPerson objects). Therefore, you will need to execute setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms in each domain containing Exchange servers or mailboxes.
Note: Unlike previous versions, in Exchange 2013, you cannot uninstall a single role from a multi-role server. For example, if you deploy the CAS and MBX roles on a single machine, you cannot later execute setup to remove the CAS role; you can only uninstall all server roles. Mailbox Sizes in Exchange Server 2013As you start migrating your mailboxes to Exchange 2013, one thing you may notice is that your mailboxes appear to be larger post move.As you can imagine, with hosting millions of mailboxes in Office 365, accurate storage reporting is essential, just like in your on-premises deployments.
One of the learnings that we accrued into the on-premises product is ensuring that the mailbox usage statistics are more closely aligned with the capacity usage within the Mailbox database. The impact of reporting space more accurately means that mailbox quota limits may need to be adjusted prior to the mailbox move so that users are not locked out of their mailbox during the migration process.Our improved space calculations may result in a mailbox’s reported size increasing on average of 30% when the mailbox is moved from a legacy version of Exchange to Exchange 2013. For example, if a mailbox is reported as 10GB in size on Exchange Server 2010, then when the mailbox is moved to Exchange 2013, it may be reported as 13GB. This does not mean that migrating to Exchange 2013 will increase your capacity footprint by 30% per mailbox; it only means that the statistics are including more data about the space the mailbox consumes. 30% is an average value, based on what we have experienced in Exchange Online. Customers with pilot mailboxes should determine what their own average increase value may be as some environments may see higher or lower values depending on the most prevalent type of email within their mailboxes. Again, this does not mean there will be an increase in the size of the database file on disk; only the attribution of space to each mailbox will increase.
New Functionality Included in Cumulative Update 1Exchange 2013 RTM CU1 includes a number of bug fixes and enhancements over the RTM release of Exchange 2013. Some of the more notable enhancements are identified below. Address Book PoliciesAs discussed recently, an Address Book Policy Routing Agent has been included in Exchange 2013 RTM CU1. For all the juicy details, see.
Groups can once again manage groups!In Exchange 2010 you could not use a group as an owner for another group for membership management. Instead you had to deploy explicit permissions on groups or use a as a workaround.Since Exchange 2010’s release both Microsoft Support and the Exchange Product Group received resounding feedback on the need for this capability.
The good news is that with Exchange 2013 RTM CU1 groups can once again be owners of groups for membership management. Public Folder Favorites Access through Outlook Web AppIn Exchange Server 2013 RTM there was no way to access Public Folder content through Outlook Web App. In CU1 you will now have access to Public Folders you have added as favorites via your favorites menu either in Outlook or Outlook Web App. However, this access is limited to Public Folders stored on Exchange Server 2013.Figure 3: Adding a Public Folder as a favorite in Outlook Web App in Exchange Server 2013 RTM CU1Remember, you cannot start creating Public Folders on Exchange Server 2013 until all users have been migrated to Exchange Server 2013. For how to migrate from legacy Public Folders to Exchange Server 2013 Public Folders, see. Exchange Admin Center EnhancementsThe (EAC) has been enhanced and now includes Unified Messaging management, improvements in the migration UI allowing more migration options reducing the gap between PowerShell and the UI, and general overall improvements in the user experience for consistency and simplification based on customer feedback.
High Availability and Monitoring EnhancementsThere are have been several enhancements in the high availability and Managed Availability space. In particular:. The algorithm now honors MaximumActiveDatabases. Auto-reseed now supports disks that have.
Many have been updated and improved over the RTM release. cmdlet has been streamlined and its performance has been optimized.
Exchange 2013 RTM CU1 will support the Exchange Server 2013 Management Pack for System Center Operations Manager (SCOM); this management pack will be available at a later date. This management pack is supported on SCOM 2007 R2 and SCOM 2012.On behalf of the Exchange Product Group, thanks again for your continued support and patience, and please keep the feedback coming. I'm getting performance counters errors after installing. Errors like this:Performance counter updating error. Counter name is Current Connected Sessions, category name is MSExchangeRemotePowershell.
Optional code: 3. We just finished a CU1 deploy at a greenfield site (sole Exchange 2013 RTM).Happy to report that once we figured out the prerequisites needed on Server 2012, running the AD prep steps, and then CU1 itself that our Exchange 2013 RTM to CU1 update was successful.We are now getting some weirdness in the Event Logs such as service failure and restart attempts with (service already started) on MS Exchange RPC Client Access Service.
Exchange Search Service seems to be crashing, and then we are getting MSExchangeFASTSearch exception errors.While the above seems to have been introduced with CU1, the fact that OWA now performs a LOT better than before and MIME based PDF attachments via copiers are no longer killed has brought some happiness to our client!:)Philip.
Server roles in Exchange 2013/Exchange 2007 hybrid deployments. 2/8/2020.
5 minutes to read.In this articleWhen you configure a hybrid deployment in an Exchange 2007 organization, you have to install at least one Exchange 2013 server with the Client Access and Mailbox server roles in your existing Exchange 2007 organization. The Exchange 2013 Client Access and Mailbox servers coordinate communications between your existing Exchange 2007 on-premises organization and the Exchange Online organization. This communication includes message transport and messaging features between the on-premises and Exchange Online organizations.We highly recommend installing more than one Exchange 2013 server in your on-premises organization to help increase reliability and availability of hybrid deployment features.

Server roles in a hybrid deploymentHere is a quick overview of the Exchange 2013 server roles in a hybrid deployment:.Client Access server role: The Exchange 2013 Client Access server role continues to provide many of the same functions that are typically provided by Exchange 2007 Client Access servers in your organization with some additions required to support a hybrid deployment and coexistence with Exchange 2007. The Client Access server also handles secure mail messages sent from the Exchange Online organization to the on-premises organization, as well as handling transport rules, journaling policies, and message delivery to Mailbox servers in a hybrid deployment. A dedicated Receive connector is configured by default on the Client Access server to support secure hybrid mail transport. All client connectivity, including Outlook client access, Outlook Web App, and Outlook Anywhere goes through the Client Access server role. Organization relationship features between the on-premises and Exchange Online organizations, such as free/busy sharing, are also handled by the Client Access server role.Learn more at.Mailbox server role: The Exchange 2013 Mailbox server role handles secure mail messages sent to the Exchange Online organization from the on-premises organization. Although not typical, it also can host on-premises recipient mailboxes and communicate with the Exchange Online organization by proxy via the on-premises Client Access server.
