When you try to connect to the Microsoft Exchange Server 2016 Outlook on the web, Exchange Server 2013 Outlook Web App (OWA), or Admin Center (EAC) page, you're redirected to Exchange Server 2010 OWA or Exchange Control Panel (ECP). This issue occurs under the following circumstances:


To work around this issue, you can access the EAC by adding the Exchange version to the URL. For example, to access the EAC whose virtual directory is hosted on the Exchange Server 2013 Client Access server, use the URL: =15.

Microsoft Exchange Server 2010 and Exchange Server 2007 have multiple server roles: Client Access, Mailbox, Hub Transport, Unified Messaging, and Edge Transport. With Exchange Server 2013, we reduced the number of server roles from five to three: Client Access, Mailbox, and Edge Transport. Unified Messaging is now considered a component or sub-feature of the voice-related features that are offered in Exchange 2013. (For more details about the changes, see "Exchange 2013 architecture" in What's new in Exchange 2013.)

When you're upgrading your existing Exchange 2010 organization to Exchange 2013, there's a period of time when Exchange 2010 and Exchange 2013 servers will coexist within your organization. You can maintain this mode for an indefinite period of time, or you can immediately complete the upgrade to Exchange 2013 by moving all resources from Exchange 2010 to Exchange 2013, and then decommissioning the Exchange 2010 servers. You have a coexistence scenario if the following conditions are true:

You can't upgrade an existing Exchange 2003 organization directly to Exchange 2013. You must first upgrade the Exchange 2003 organization to either an Exchange 2007 or Exchange 2010 organization, and then you can upgrade the Exchange 2007 or Exchange 2010 organization to Exchange 2013. We recommend that you upgrade your organization from Exchange 2003 to Exchange 2010, and then upgrade from Exchange 2010 to Exchange 2013.

2If you want to create an EdgeSync Subscription between an Exchange 2010 Hub Transport server and an Exchange 2013 SP1 Edge Transport server, you need to install Exchange 2010 SP3 Update Rollup 5 or later on the Exchange 2010 Hub Transport server.

To help you get an overview of the Exchange 2010 to Exchange 2013 upgrade process, we've gathered resources related to each key task in the following table. For specific step-by-step guidance, see Checklist: Upgrade from Exchange 2010.

Provide a resilient solution: Exchange 2013 builds upon the Exchange Server 2010 architecture and has been redesigned for simplicity of scale, hardware utilization, and failure isolation.

Exchange 2013 provides a single unified management console that allows for ease of use and is optimized for management of on-premises, online, or hybrid deployments. The Exchange admin center (EAC) in Exchange 2013 replaces the Exchange 2010 Exchange Management Console (EMC) and the Exchange Control Panel (ECP). (However, "ECP" is still the name of the virtual directory used by the EAC.) Some EAC features include:

List view: The list view in EAC has been designed to remove key limitations that existed in ECP. ECP was limited to displaying up to 500 objects and, if you wanted to view objects that weren't listed in the details pane, you needed to use searching and filtering to find those specific objects. In Exchange 2013, the viewable limit from within the EAC list view is approximately 20,000 objects. After the EAC returns the results, the EAC client performs the searching and sorting, which greatly increases the performance compared to the ECP in Exchange 2010. In addition, paging has been added so that you can page to the results. You can also configure page size and export to a .csv file.

Role Based Access Control (RBAC) User Editor: In Exchange 2010, you could use the RBAC User Editor in the Exchange Toolbox to add users to management role groups. In Exchange 2013, the RBAC User Editor functionality is now in the EAC and you don't need a separate tool to manage RBAC.

Unified Messaging Tools: In Exchange 2010, you could use the Call Statistics and User Call Logs tools to help provide UM statistics and information about specific calls for a UM-enabled user. In Exchange 2013, the Call Statistics and User Call Logs tools are now in the EAC and you don't need a separate tool to manage them.

Session indifference: With Exchange 2010, session affinity to the Client Access server role was required for several protocols. In Exchange 2013, the client access and mailbox components reside on the same Mailbox server. Because the Client Access server simply proxies all connections for a user to a specific Mailbox server, no session affinity is required at the Client Access servers. This allows inbound connections to Client Access servers to be balanced using techniques provided by load-balancing technology like least connection or round-robin.

Deployment simplicity: With an Exchange 2010 site-resilient design, you needed up to eight different namespaces: two Internet Protocol namespaces, two for Outlook Web App fallback, one for Autodiscover, two for RPC Client Access, and one for SMTP. A legacy namespace was also required if you were upgrading from Exchange 2003 or Exchange 2007. With Exchange 2013, the minimum number of namespaces drops to two. If you're coexisting with Exchange 2007, you still need to create a legacy hostname, but if you're coexisting with Exchange 2010 or you're installing a new Exchange 2013 organization, the minimum number of namespaces you need is two: one for client protocols and one for Autodiscover. You may also need an SMTP namespace.

Managing digital certificates is one of the most important security-related tasks for your Exchange organization. Ensuring that certificates are appropriately configured is key to delivering a secure messaging infrastructure for the enterprise. In Exchange 2010, the Exchange Management Console was the primary method of managing certificates. In Exchange 2013, certificate management functionality is provided in the Exchange admin center, the new Exchange 2013 administrator user interface.

Transport rules in Exchange Server 2013 are a continuation of the features that are available in Exchange Server 2010. However, several improvements have been made to transport rules in Exchange 2013. The most important change is the support for data loss prevention (DLP). There are also new predicates and actions, enhanced monitoring, and a few architectural changes.

Unified Messaging in Exchange 2013 contains essentially the same voice mail features included in Exchange 2010. However, some new and enhanced features and functionality have been added to those existing features. More importantly, architectural changes in Exchange 2013 Unified Messaging resulted in components, services, and functionality that were included with the Unified Messaging server role in Exchange 2010 to be divided between the Exchange 2013 Client Access and Mailbox server roles.

Automatic recovery from storage failures: This feature continues the innovation introduced in Exchange 2010 to allow the system to recover from failures that affect resiliency or redundancy. In addition to the Exchange 2010 bugcheck behaviors, Exchange 2013 includes additional recovery behaviors for long I/O times, excessive memory consumption by MSExchangeRepl.exe, and severe cases where the system is in such a bad state that threads can't be scheduled.

Lagged copy enhancements: Lagged copies can now care for themselves to a certain extent using automatic log play down. Lagged copies will automatically play down log files in a variety of situations, such as single page restore and low disk space scenarios. If the system detects that page patching is required for a lagged copy, the logs will be automatically replayed into the lagged copy to perform page patching. Lagged copies will also invoke this auto replay feature when a low disk space threshold has been reached, and when the lagged copy has been detected as the only available copy for a specific period of time. In addition, lagged copies can leverage Safety Net, making recovery or activation much easier. Safety Net is improved functionality in Exchange 2013 based on the transport dumpster of Exchange 2010.

Control how resources are consumed by individual users: Controlling how resources are consumed by individual users was possible in Exchange 2010 (where it's called user throttling), and this capability has been expanded for Exchange 2013.

AhsayOBM allows you to back up individual mailboxes in your Microsoft Exchange Server with the MS Exchange Mail Level Backup Module. This module provides a set of tools to protect your mailboxes and public folders on Microsoft Exchange Server 2007/2010/2013. This includes backup and recovery of individual emails, contacts, calendars and other mail items in your mailboxes and public folders, with snapshots / versioning, and retention policy to protect even email that you may have accidentally deleted from your Exchange 2007/2010/2013 mailboxes or public folders.

Scheduled backup is required if you choose to backup MS Exchange server 2010/2013 setup in DAG option, as AhsayOBM on all DAG members will use the scheduled backup time to start backups on all individual DAG members at the same time.

An MS Exchange server 2010/2013 DAG backup cycle is considered complete only when scheduled backup on all DAG members have been run successfully. A backup report will be generated and emailed to the recipients when a complete MS Exchange server 2010/2013 DAG backup cycle has taken place. 041b061a72
