You will get this error message when the mailbox name for the domain user account created with the exchange server administrator permissions is incorrect. Ensure that the mailbox name is configured with User principal name (User Logon name) or Samaccountname details.
The following table describes the differences between the mailbox restore features supported with Microsoft Exchange 2010 and 2013, and the features that are supported with Microsoft Exchange 2016.
Even though the client access server roles where very much present in the exchange 2010 and exchange 2007, it has been transformed a lot in the latest exchange release. Exchange 2013 CAS role consists of Client Access front end role (CAFE) and the Front-End Transport (FET). The functions of CAS role has evolved from authentication, proxy/redirection logic, and performed data rendering for various Internet protocol clients in exchange 2007 to an additional data rendering for MAPI in exchange 2010. However, in exchange 2013, CAS does not have any data rendering capability any more. The functions of CAS role is now limited to authenticating and proxy redirection logic, supporting
If the incoming request is HTTP, POP or IMAP then the request for authentication is passed through the HTTP payload. If the authentication is Forms-Based Authentication (FBA) then the encryption decryption process becomes complex. FBA cookies use a different key for different servers while encrypting. So when another server receives a request, it cannot decrypt the session. The per server decryption key is no longer used in exchange 2013. The key is now obtained from the certificates installed on the CAS. If same certificates are deployed throughout the CAS, then the decryption is possible.
In order to increase the stability and the connectivity reliability, exchange 2013 houses an important architectural change. RPC/TCP is no longer an available connectivity solution. Instead, exchange now uses RPC/HTTP (Outlook Anywhere).
With all the architectural changes, third party MAPI products suffer some blows. They now have to leverage RPC/HTTP to connect to CAS in exchange 2013. Users can download MAPI/CDO which support for RPC/HTTP connectivity to facilitate third party MAPI products. However, your third-party vendor should now support RPC/HTTP.
Having said that, it is to be noted that custom MAPI/CDO solutions are supported by the exchange 2013 which may, in future require the third-party products to move to Exchange Web Services (EWS) to access Exchange data.
All SMTP sessions in the exchange 2013 is handled by the Front-End Transport service. Besides managing the incoming and outgoing SMTP traffic for the organization, it act as a client endpoint for SMTP traffic. It act as a layer 7 proxy and has full access to the protocol conversation. It is stateless, cannot perform message bifurcation and does not have a message queue.
Front end transport service act as a proxy for outgoing messages if the FrontEndProxyEnabled property is set for Send Connecters located on the mailbox server. These messages will look like they are coming from a CAS of exchange 2013 system.
How does Exchange 2013 determine which Exchange 2010 server to proxy to when the Exchange 2010 mailbox lives on a server that only hosts the mailbox role and not client access. The example I have is if an Exchange 2010 mailbox connects with IMAP to a Exchange 2013 CAS server that fronts IMAP, through testing we know that the Exchange 2013 will always proxy to the Exchange 2010 CAS/MBX server that hosts the active database copy for where the mailbox lives. But if the mailbox lives on a server that only hosts the mailbox role, any CAS server will be chosen which seems at random in order to establish the connction. Would it be possible to control which Exchange 2010 servers are available for CAS selection by Exchange 2013 or set a weight/cost to them
I have one query related to SMTP Mail flow from Internet. If there are two AD sites having Exchange 2013 deployed in HA mode in same Exchange Organization. Both have individual local DAG ( Say DAG1 for site A & DAG2 for Site B ) Site A is Internet facing site. If incoming mail sent from external domain meant for a recipient in DAG2, will the Exchange 2013 CAS at Site A will send the mail directly to Exchange 2013 CAS server in Site B or mail will first go to Exchange 2013 Mailbox server in Site A first, which then route it to Exchange 2013 Mailbox server in Site B.
Hi RatishWant to deploy an additional Exchange 2013 on a remote site (Same AD) and move a small number of mailboxes there. This remote site is linked to corporate via a VPN Tunnel. The MX record points to a spam filter device at the main Exchange site (Corporate). If emails come to a mailbox in the remote site, will CAS know to re-direct them through the VPN Tunnel, to the appropiate exchange server Will there be a way, perhaps adding another MX record, and a spam filter, to have users connect directly to the remote site, instead of going through corporate site spam filter Thanks
There has been a few removals and additions to the 2016 version of exchange server. In MS Exchange Server 2016, Client Access Server Role is a service that works with Mailbox Server. In 2013 Exchange Server, it was a separate service; however, this server role has been integrated into the 2016 version of the mail server. Another change is that anything that uses the MAPI/CDO library has to be switched with one of these three options:
Hi Experts, I had been primarily a RHEL guy in the past. Currently, I have 3 Node (All-in-one) Exchange 2013 DAG (all 3 nodes are virtualized in Hyper-V 2012 and are a part of HyperV2012 Cluster). In DNS, I have created 3 A records for mail.domain.com which resolve to to the Public IP addresses (MAPI IP address) of all 3 CAS servers. And I have also enabled Outlook anywhere. OWA internally is working fine.
That's exactly what I have done but one fundamental query: themail.domain.com A Record should point to which IP address In my case I have pointed it to the MAPI IP addresses of all 3 Exchange servers (so, its Round-robin). But, I believe its an incorrect approach because then I am unable to figure out what IP address should I use as the VIP of Load balancer. Ultimately, the Load Balancer VIP should should resolve to mail.domain.com. But, if I do not use the IP address of all 3 exchange servers in DNS, how would the virtual directories (mail.domain.com/owa & mail.domain.com/ecp) be able to resolve to a IP address. So, this presents a quandary to me. mail.domain.com needs to be resolve to VIP of Load balancer but if I do it, it does not work because that VIP does not point to any actual IP address.
The Exchange 2013 Managed Store also reduces the number of potentially mounted databases per mailbox server from 100 (Exchange 2010) to 50 (Exchange 2013). This change should aid companies that rely on database availability groups (DAGs) as part of their general Exchange Server infrastructure.
There is no more public folders in exchange 2013.Instead the public folders are created and associated to a parent public folder mailbox. There is no separate public folder DB in exchange 2013.Discussions can be stored, indexed, and searched

What could be the cause when the access to the Microsoft Exchange server is not possible, for example public and private Outlook contact folders cannot be added to the XPhone Connect Directory or Virtual Directory, calender synchronization between the XPhone and Exchange server does not work or you cannot access your Voicemail via MAPI
A mailbox user connecting via Outlook 2013 is connected to server E15MB2, as shown here in the Outlook connection status dialog. There was no manual configuration required for this, it is just how Outlook autodiscovered the endpoint to connect to.
Without the aid of a load balancer the Outlook clients takes about 20 seconds to time out and then re-establish connectivity to the other IP address that mail.exchange2013demo.com resolves to. A much better user experience than before the Outlook Anywhere namespace was configured on the Client Access servers.
Thanks for your reply. I have an existing exchange 2007 with 600 mailbox. I installed the server role as I mentioned and migrated some mail box to new server. DAG also in place. So is it possible or required to go back
Environment Descsription : In my environment i am using MAPI over HTTP as the protocol and all of my exchange servers are attached to the HW load balancer .So first my outlook client will connect to LB and from there outlook connections will get proxied to the exchange server which holds my user mailbox.
I have 2 mailservers and they are both CAS and DAG member. I use DNS RR, it works fine but my question is Send and receive connectors. If main server goes down, what should I do to send emails to external contacts
Hi @paul,first of all i am really thankful that you have made the migration guide.I have basically Followed your Migration guide from exchange 2010 to Exchange 2013 and this guide has helped me so much with understanding the concept about the exchange.
