You need to upgrade them or demote them. Outlook clients should be the following or higher. Outlook 2. 01. 0 SP2 or later with KB2. KB2. 96. 52. 95 (These patches provides Mapi/http)Outlook 2. SP1 or later with KB3.
This patch fixes shared mailbox and legacy Public Folders)- Mailbox Server Role will do the following. Authenticate Clients Do a directory look up. Determine the mailbox version. Location of the mailbox database. Decision on proxy or redirect. Also determine how store process and data rendering.- Mailbox Server Role Changes. Only IP Less DAGStill 1.
Still 1. 00 DB copies per server. Still ESE Database engine.
Replay lag manager will be enabled by default which means if we have 2 passive database copies then 3rd passive database copy will be Lag copy which will not require to be enabled. Similar in case of losing one database copy lag copy will automatically commit the logs and become 2nd passive copy. New IO latency monitor will be monitoring disk IO and don’t replay the logs in case lag copy requires to replay the logs. Database failovers will be 3. Indexing Improvement: Indexing search for the passive database copy will be done locally through passive database copy. Before Exchange 2.
Index which has consumed lot of CPU and network bandwidth. Have a look into the indexing architecture.- Office Web Apps Server Role provides the following: Content rendering for MS office attachment files. Rich browser viewing. Side by side viewing and editing of attachment in OWA.
Pulling the attachments from share point.- MAPI/CDOTime to say bye to MAPI/CDO. Blackberry 5x will not work. Any app uses MAPI/CDO would needed to be updated- Client Protocol Architecture - MAPI/HTTPMicrosoft introduced in Exchange 2. SP1. In Exchange 2. SP1 it used to be disabled. In Exchange 2. 01.
In Exchange 2. 01. In Exchange 2. 01. We will also be able to control if autodiscover should expose Mapi/http configuration or not. Pop up “administrator has made some changes so restart outlook” will not come. It will wait for the user to restart outlook. Remove RPC stack dependency which means no RPC over http. More reliable connection and faster connection with hibernation feature.
Improved diagnostics. Mapi/Http connectivity architecture will be following- Connectivity Flow in Exchange 2.
Co- existence with 2 AD Sites. It will be same as Exchange 2. Exchange 2. 01. 0 in the same AD site – Proxy. Exchange 2. 01. 0 in the different AD site – Proxy. Exchange 2. 01. 0 in the different AD site – Redirect- Connectivity Flow in Exchange 2. Co- existence with 2 AD Sites – same flow either Exchange 2. Exchange 2. 01. 3 in the same AD site Exchange 2.
AD site – Proxy Exchange 2. AD site – Silent Redirect- Use Form based Authentication on both source and destination - Outlook Web Apps Server Connectivity Flow – Optional Server.
Exchange will use discovery URL(similar to autodiscover url) to query Outlook Web Apps Server what are the file types it can view and edit. Outlook Web Apps Server replies table of supported file types like MSword, MSExcel, MSOne. Note, etc. User opens email with attachment that matches one of the file types Outlook Web Apps Server supports and OWA requests document URLs for supported types. Exchange builds URL with Authentication token, app URL, and Attachment ID then reply it to OWAUser clicks attachment within Outlook Web App and responds an iframe to load the URL returned by Exchange. Outlook Web Apps Server pulls document content from Exchange.
Outlook Web Apps Server renders content in Outlook Web Apps Server client- Exchange Namespace. Microsoft has recommended to have separate namespace internalurl and externalurl for outlook anywhere and mapi/http so that separate authentication can be used for intranet (Kerberos) and internet (NTLM or Basic) connection. But it is only useful when we have internalurl which in not available on Public DNS. I have explained namespace requirement here. Healthcheck. htm is helping in identifying if protocol is up or down. It is recommended to use 2 Load balancer type Round Robin (mapi/http does not see any issue but RPC over http might have issue with long connections) or Least Connections (should use slow start feature). Preferred is Least connections with “slow start” feature.
Single namespace Layer 7 is preferred (no session affinity) and recommended because one protocol will allow remaining protocols. SSL termination at LB would be required. If you need to use layer 4 then you should use multiple namespace. LB will not stop other protocol connections if one protocol fails. This will increase SAN names in the cert and its cost will go high. This is not recommended.- Outlook Web App Server Namespace and Load Balancing. Deploy separate namespace.
Follow a bound namespace model for site resilience. Load Balancer Persistence is required. Exchange will connect to the local AD site Outlook Web App Server- Exchange 2.
Preferred Architecture. For Exchange Single namespace for both datacenters should be used.
Autodiscover. domain. Mail. domain. com. For OWAS deploy 1 namespace per datacenter. Load Balancer Configuration. For Exchange VIP: One VIP Layer 7 per datacenter with no session affinity and per protocol health check. For OWAS VIP: Session Affinity.
DNS host entries in the Public DNS for round robin connectivity and equally distribution of clients to both the datacenters. Every datacenter should be a separate AD site so DAG should expended to 3 AD Sites. Don’t stretch AD site because safety net keep shadow copy on a mailbox server in the 2nd AD site.
Unbound namespace. Symmetric DAG model with same number of servers in each datacenter and same number of database copies in each datacenter. IP less DAG (No Administrative Access Point)Replication and Client connectivity through single network.
File share witness in the 3rd Datacenter/Azure. Distribute active copies to all DAG nodes. Passive datacenter with 1 lag copy(7 days) with automatic log play down.
Use Native Data Protection which will eliminate the need of 3rd party backup. Dual- socket systems only (Total 2. Up to 1. 96. GB of RAM (Memory)JBOD Disks. Large size 7. 2. K SAS disks. Battery- backed cache controller must be deployed (7.
Auto. Reseed with 1 or 2 hot spare. Data Volumes should be formatted with Re. FS (Resilient File System)Data Volumes should encrypted with Bit. Locker. Keep archive mailbox in the same database as primary mailbox. Increase knowledge worker productivity. Eliminate PSTEliminate 3rd party archive solutions. Control OST size.
Edge Transport or Exchange Online Protection should be used to send and receive the emails as front- end. SMTP gateway can be used as 2nd option. This blog ends here. Feel free to watch here the Exchange 2. Architecture session of Ross Smith IV’s ignite session at channel 9 .

How to Re- register VSS Volume Shadow Copy Service in Windows server 2. R2. Lets says Backup runs on your Exchange Server. Where it failed due to Disk space or some connectivity issues. VSS – Volume Shadow Copy Service – is responsible for your Backups on your Exchange Server.
To Check for your Available writers you can run the below command in your command prompt. Vssadmin list writers. And some writers may be unstable or in waiting for completion state. Especially “Microsoft Exchange Writer”if that is unstable or waiting for completion for a long time , Eventually your Next backup will fail.
You can try restarting Microsoft Exchange Information store Service to refresh itor you can reboot the serverto get the writers back to stable. If nothing could get your writers to stable state. As a Last resort you can try Re registering the Vss dlls. Re- registering Vss Dlls. Microsoft Dynamics Ax Vs Sap Business One Tutorial.
