Redundant Hub and CAS roles for exchange server

Hello ,
currently we have 2 mailbox servers , 1 DAG server and 1 HUB,CAS server ( hub and cas roles in same server )
i am looking to have a backup server incase the hub CAS server goes down .. or to have a redundant server for HUBCAS incase if it goes down the other one will go up and the users will use the second one automatically
how can i achieve that ?
appreciated your help

Hello,
If you use exchange 2010 server, I recommend you deploy multiple CAS servers as member of CAS array.
As your requirement, you need to deploy CAS NLB, the failover will occurs automatically.
Here is an article for your reference.

Send As, Send on Behalf and Full Access for Exchange server 2010/2013

[This FAQ contains 2 parts]
Testing and watching the behavior of Send As, Send On Behalf and Full Access permission.
Common issue and Troubleshooting on the three permission.
[Testing and Watching]
Based on following blog, I decide to test on my lab:
Full Mailbox Access Rights + Send On Behalf = Send As ?
http://blogs.technet.com/b/ehlro/archive/2012/04/06/full-mailbox-access-rights-send-on-behalf-send-as.aspx
Description on my lab and test:
Exchange 2010 + Outlook 2010
Exchange 2013 + Outlook 2013
Senders: A01, A02, … , A07, A08
Recipient: A09
A01 grand permission to other senders.
Two methods:
a. Use A0x’s credential configure A01’s profile, then send From both A01 and A0x via Outlook. Watching result in A09’s Inbox and Sent Items which has message copy left.
b. Use A0x’s credential configure A0x’s profile, then send From both A01 and A0x via Outlook. Watching result in A09’s Inbox and Sent Items which has message copy left.
Result as following forms:
1. Exchange 2010 + Outlook 2010 / Exchange 2013 + Outlook 2013
Using A0x’s credential configure A01’s mailbox, then send From both A01 and A0x
To A09.
2. Exchange 2010 + Outlook 2010 / Exchange 2013 + Outlook 2013
Using A0x’s credential configure A0x’s mailbox, then send From both A01 and A0x
To A09.
[Common Issue]
1. [Issue]
Exchange 2010 + Outlook 2010. A01 grand A03 Send As permission. However A03 can’t send as A01 to A09 and get NDR:
You can’t send a message on behalf of this user unless you have permission to do so. Please make sure you’re sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.
Details as following pic:
[Troubleshooting]
1) Based on the NDR, it seems a permission issue. Check Send As permission, however the Send As permission configured correctly. Pic as below:
2) ince the Send As permission configured correctly, it seems the permission hasn’t been replicated. Try to restart Microsoft Exchange Information Store service. It works.
Note: The Send As permission isn’t granted until after replication has occurred. Replication times depend on your Exchange and network configuration. To grant the permission immediately, stop and then restart the Microsoft Exchange Information
Store service.
2. [Issue]
Exchange 2013 + Outlook 2013. A01 grand A03 Send As permission. However A03 can’t send as A01 to A09 and get NDR:
Your message did not reach some or all of the intended recipients.
Subject: xxx
Sent: xx/xx/2014 8:20 AM
The following recipient(s) cannot be reached: A09
This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80070005-00000000-00000000].
Details as below:
[Troubleshooting]
1) Also check the Send As permission configuration first.
2) Then try to use A03 send as A01 to A09 via OWA. If OWA works well, it seems and issue on the Outlook client side.
3) This behavior may occur if the OAB in Outlook isn’t updated. Try to download OAB manually.
4) If doesn’t work, please close Outlook and try to delete all the OAB folder on your computer. The path of OAB folder in Win7, Win8 as below:
\Users\<UserName>\AppData\Local\Microsoft\Outlook\Offline Address Books
5) Restart Outlook.
Note: Be aware that you cannot send e-mail messages on behalf of a mailbox if the mailbox is hidden from address list. When sending a message, Exchange requires that e-mail address is resolved in the
From field.
3. [Issue]
Exchange 2010. A01 grant A0x “Send As” or “Send on Behalf” permission. A0x send as/ send on behalf of A01. The message is only copied to the Sent Items folder in A0x’s mailbox (same as the result of my test). Also cannot configure Exchange 2010 so that the
message is copied to the Sent Items folder of both A01 and A0x.
[Troubleshooting]
This issue occurs because Exchange server 2010 was designed to copy message to the Sent Items folder of the sender only. This issue can be solved by installing Exchange 2010 SP2 UR4. More details in the following KB:
Messages that are sent by using the "Send As" and "Send on behalf" permissions are copied only to the Sent Items folder of the sender in an Exchange Server 2010 environment

Nice guide Mavis, I recently explored the same topic. Few things you might want to add is the type of connectivity (Cached vs Online will produce different results) and to expand further on the methods of adding the other mailbox in Outlook (additional mailbox
vs additional account defaults to different methods). Check the screenshot:
And please post this somewhere more visible, like blog/wiki page.

Exchange 2010 server (Mail,HUB and CAS) installation in new site.

We are planned to install Exchange 2010 servers(MAIL,HUB and CAS) server in new Active director site in existing exchange organization.
Kindly share best practice link for exchange server installation in new site.

The best practice for installing into a new Active Directory site is the same as installing into a new organization, except you don't need to prepare the organization or domains (unless you are also installing into a new domain that hasn't been prepared).
Install the CAS then hub, then mailbox roles, or install a multi-role server, then define your CAS Array name and IP address, and set your CAS behind a load balancer (if needed). Add your external certificate to both the CAS and the load balancer (and the
hub if you use TLS for mail transfer), and you should be golden. Also, if you intend to proxy your CAS connections, here's a link that may help:
https://technet.microsoft.com/en-us/library/bb310763.aspx?f=255&MSPPError=-2147217396
For completeness, here's a thread on the msexchange.org forums that specifically mentions adding Exchange into a second site:
http://forums.msexchange.org/New_Exchange_2010_at_another_Site/m_1800557445/tm.htm

Our exchange server crashed and we lost all contact and calendar data. We found an app to get the contacts off of people's phone to import but can't find the same for calendar. How do I get my calendar info off my phone and in to new exchange server?

You'd have to think through this, but it seems like if you are using Outlook, and the items vanished from the Outlook client as well as the server,that you could re-populate Outlook using iTunes.

Cumulative Update 5 for Exchange Server 2013 (KB2936880)

Hi,
i have installed exchange server 2013 on separate servers, I deployed the Mailbox role on the first server, and the CAS role on the second server.
I checked the edition using the exchange management shell on the mailbox server and on the CAS server:
>>>
[PS] C:\Windows\system32>Get-ExchangeServer | fl name,edition,admindisplayversion
Name : EXMBX
Edition : Standard
AdminDisplayVersion : Version 15.0 (Build 516.32)
Name : EXCAS
Edition : Standard
AdminDisplayVersion : Version 15.0 (Build 516.32)
<<<
My question is, is it possible to update this current edition to the "Cumulative update 5 for Exchange Server 2013 (KB293688) ?
if it is, in my case, on which servers should i install this update ? on the Mailbox server ? or on the CAS server ?
i appreciate you fast response,
Thanks.

Hello,
It doesn't matter which build you choose: you should first update the mailbox role and then CAS. The best option is to have same version of all your Exchange servers (e.g. CU5).
It is not necessary to install Exchange binaries on DC.
Hope it helps,

Sizing IIS ARR for Exchange Server 2013

Hi Everyone,..
I planned to publish Exchange 2013 through IIS ARR server, but I've had trouble finding any data on CPU / memory usage for a dedicated ARR server based on Microsoft recommendation. There are 8000 users that will be access from ARR server.
Hopefully you can help for sizing so
there isn't bottleneck on that server.
Thanks
~IH~

Hi Irfan
The concurrent connections depends upon appConcurrentRequestLimit which has a default value of 5000. I think you need to increase this if in your case the concurrent connections exceed 5000

When one of our CAS servers got patched they installed Rollup 4 for Exchange Server 2010 SP3.

thanks for your reply!
what's protection software can use for exchange server 2013?
Hi,
Most (if not all) of the bigger vendors has a product that supports Exchange 2013, so look them up.
Exchange 2013 has some Anti-Spam and Anti-Malware Protection functionality that you can read about here:

Renewal of Forefront Protection 2010 for Exchange Server until EOL

Hello,
We have a Open Value subscription for Forefront Protection for Exchange Server 2010 (FPE) running with an Exchange 2007 server and an Edge Server. We attempted to renew the subscription to FPE and were automatically upgraded to FOPE and now EOP.
Since FPE is not End of Life yet, might it be possible to renew FPE on premises until such time as the product goes End of Life?
thank you,
Dan

Hello,
FPE on premises was available only as a subscription license in OV, OVS. for subscription products thre is not possibility to renew th elicensing if is removed from product list.
you can purchase FOPE(in OVS) or EOP as online subscription. you can use also EOP for on premises Exchnage Server.
on Microsoft document we have th efollowing info:
The following are the primary ways you can use EOP for messaging protection:
In a standalone scenario   EOP provides cloud-based email protection for your "on-premises Microsoft Exchange Server 2013 environment, legacy Exchange Server versions,
or for any other on-premises SMTP email solution."
As a part of Microsoft Exchange Online   By default, EOP protects Microsoft Exchange Online cloud-hosted mailboxes.
In a hybrid deployment   EOP can be configured to protect your messaging environment and control mail routing when you have a mix of on-premises and cloud mailboxes.
note: EOP replaces Microsoft Forefront Online Protection for Exchange (FOPE). All FOPE customers will be transitioned to EOP, as described in the
Forefront Online Protection for Exchange (FOPE) transition center. EOP delivers the protection and control provided by FOPE, and also includes additional features.
What's new in Exchange Online Protection describes some of these features.

Microsoft forefront protection 2010 for exchange server is unable to perform the requested function

I get the following error any time I try and change any setting:
Microsoft Forefront Protection 2010 for Exchange Server is unable to perform the requested function. This may be becuase Microsoft ForeFront services are unavailable. Ensure that all Microsoft ForeFront services are running and that Windows Powershell is
functional.
I have installed the latest rollup for SEP. Rollup 5 I think. I have rebooted the server. I have checked the permissions and they are correct.
Any thoughts?

I posted a PowerShell-based workaround in the other thread:

Expiration of "Subscription license of Microsoft Forefront Protection for Exchange Server"

We have "Microsoft Forefront Protection for Exchange
Server" running in the company. Now I face the expiration of "Subscription license of Microsoft Forefront Protection for Exchange Server".
I learned from
http://blogs.technet.com/b/server-cloud/archive/2012/09/12/important-changes-to-forefront-product-roadmaps.aspx that "... products will continue to be supported through that date (12/31/2015) in order to provide with customers sufficient
time to move to alternative solutions". My concern is, that Microsoft Forefront Protection for Exchange Server does not know about that grace period.
It claims:
Your Subscription license of Microsoft Forefront Protection for Exchange Server has expired. The product will continue to operate during the extended grace period
until 5/1/2013. Subsequently, scanner updates will be disabled and the product will operate with reduced functionality.
Is there a way to get a new license number? I called our software vendor, but Microsoft does not sell licenses anymore.
Thank you for your assistance.

Proper IMAP prefix for Exchange Server

Does anyone know what the proper IMAP prefix is for Exchange Server?
Currently, I have specified "INBOX". On the iPhone, I can see my inbox, and all subfolders, but I can't see any other folders on the same level as inbox. Also, the iPhone has created "Sent Items" and "Deleted Items" folders UNDER my inbox and is using those instead of the ones Exchange uses at the same level as inbox.
I tried specifying "/", which wouldn't let me access anything. There doesn't appear to be a way to leave the prefix blank (the iPhone auto-fills "INBOX" if you blank the field), so I haven't been able to try that.
Any ideas? Thanks!
iPhone

You're right. It did. Using an IMAP account instead of an Exchange account allowed me to see all folders at the same level as "inbox". Thanks!
But, what's the point of the "Exchange" account then?
