OWA setting for additional exchange server 2010

Hi,
I have exchange 2010 owa setup with public ip address for activesync, owa etc. I just installed a second exchange 2010, How does OWA going to work for this second exchange? I would like it to use the same certificate and ip from the first exchange
server. Just making first server as front end, IIS enabled and second server as just backend. Is it possible? Any advise will be greatly appreciated.
e. John's mailbox is server1. He can login to OWA. Mary is on server2. Can she login to the same OWA address as John?
Many thanks,
pwint

As per your description you are not going to have these servers in CAS array. If that's the case you can follow the below steps
Modify the following entries in SAN
SAN1 - outside.domain.com ( keep it as it is and do not modify)
SAN2 - servername1.domain.local
SAN3 - servername2.domain.local
SAN4 - server1name (NetBios Name)
SAN5 - Server2name (netbios name)
SAN4 - autodiscover.domain.com (assuming domain.com should match your email addresses)
SAN5 - mobile.domain.com
That's it you are done and you do not need to make any other changes apart from this.

There's a pre-release build of the exchange collector available for
2010, just contact NTS.
If you need a full formal release, we're looking to have 2010 and 2013
support by approximately mid-year.

How to install Exchange Server 2010 with the name of my existing Domain Controller.

I have my Primary domain Controller as abc.com in 2008 r2 standard. abc.com is registered. I want to set up Fresh Exchange Server 2010 sp2 with the name of the same
abc.com domain name. Please guide me the steps how to do that. Waiting for your kind response. :)

Hi,
From you description, you want to install an Exchange server 2010 in the abc.com. When you set up your Exchange, Exchange need to join in a domain. You just need to specify the domain to abc.com.

Installing Exchange server 2010 on Server 2012

I understand that SP3 supports Server 2012.
Looking at the size of the extracted files on SP3 this is not a slipstreamed later version of Exchange right?
Am I also right in thinking, I just need to:-
- Update the schema and Domain prep it
- Use the Exchange 2010 with SP1 disk to complete base install and then apply SP3
Does that sound about right?

Hi,
Apart from the suggestions above, before you decide to install Exchange 2010, please make sure you meet the Exchange 2010 installation prerequisites. For more details about Exchange 2010 prerequisites, you can refer to the following article.
http://technet.microsoft.com/en-gb/library/bb691354(v=exchg.141).aspx
And here is a related article about how to prepare Active Directory and domains for installing Exchange Server 2010 which may help you.

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:

Exchange Server 2010 - OWA, ECP, EWS not working

Hello,
I am evaluating exchange server 2010. I was able to install it, but now the admin websites will not render in IIS. OWA, ECP, etc. I especially want Outlook Anywhere to work. I can admin through the windows admin interface so that's not a concern.
I want users to access their email through the web as well. I checked permissions but could have them wrong. Any help is appreciated.
Thanks
John Grace

There are about twenty different types of 403 error. To see which one is happening here, you'd need to look at the IIS log files, and get the status subcode, which is the number after the 403 in the logged line.
The most common, though, is 403.4, which means 'SSL Required'. What happens if you go to
https://servername (i.e. https instead of http).
Another one is 403.6, which means that IIS has been configured to only allow access to a certain range of IP address, and the one you're trying to access it from isn't one of them.

Exchange Server 2010 OWA Error 405 StaticFileModule

I am running Exchange Server 2010
(Version 14.1 - Build 218.15) on Windows Server 2008 R2. This is a all-in-one-server roles installation. Everything is working fine except forms-based authentication. When enabled I get HTTP Error 405.0 "Method not allowed". The page
you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.
Details are:
Module StaticFileModule
Notification ExecuteRequestHandler
Handler StaticFile
Error Code 0x80070001
Requested URL https://localhost:443/owa/auth/owaauth.dll
Physical Path C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\owa\auth\owaauth.dll
Logon Method Basic
Logon User administrator
When in EMC, Client Access, on OWA & ECP tabs I change authentication forms-based to standard with basic check box and restart IIS the Web Access works fine.
I have already tested solutions like recreating Virtual Directories, Allow .Net 2.0, etc. I have also checked all the modules and the associated mappings in IIS one by one for every VM. I believe this is an error in a .config file. If you have encountered
a situation like this please help.

Hi Pantelis,
Please make sure that the client sends a request that contains a valid HTTP method.
1. Click Start, type Notepad in the Start Search box, right-click
Notepad, and then click Run as administrator.
Note If you are prompted for an administrator password or for a confirmation, type the password, or provide confirmation.
2. On the File menu, click Open. In the
File name box, type %windir%\system32\inetsrv\config\applicationhost.config, and then click
Open.
3. In the ApplicationHost.config file, locate the <handlers> tag.
4. Make sure that all the handlers use valid HTTP methods.
5. Save the ApplicationHost.config file.

Exchange Server 2010 - Receive Connector for Client Computers

I have one customer with a SBS 2011 with Exchange Server 2010 - a pretty standard setup except for some customisation with Receive Connectors in order to cater for an application which is installed on a number of computers that requires to use an SMTP Server
to send notifications. In order to accomplish this (allow to be sent using Exchange Server) we added the IP Address of client computer (which we also set as a DHCP reservation) to a pre-configured Receive Connector (Anonymous setup for Printer/Scanner).
This worked fine, but we now find that there are other applications that require the same function to use SMTP to send.
How should/could this be better configured so an application can send if they authenticate?

Hi
For this you need to create a seperate receive connector to be used for Relay in your organizations.
Follow the below steps
1) Create a dedicated Relay Receive Connector
2) Add only the Ip addresses of the applications which needs to relay on Exchange servers
3) You can use either anonymous or authenticated relay according to your relay config
You can follow the below link as well

Exchange 2010 Mailbox automapping issues after updated to Rollup 5 for Exchange Server 2010 SP3

Hi,
i have problem with Outlook Uses who have Full Access on other mailbox.
An authentication window pop up very time a user start Outlook.
If i remove the access everything is ok.
if i insert manual the mailbox everything is ok
The System was for 3 days ago updated to Rollup 5 for Exchange Server 2010 SP3
Before the update, was no issue.
i will appreciated any help
Thanks

Same issue here. Ever since we installed Update Rollup 5 for SP3 Exchange 2010 mailboxes that were auto mapped are not accessible. They all get the same error.
Cannot expand the folder. The set of folders cannot be opened. The attempt to log on to the Microsoft Exchange has failed.
What I have been doing is removing the users permission, then adding them back using the noautomap switch in Powershell. After doing that, the user manually adds the mailbox and all is well.
Just a note here, I suspect it may have something to do with the version of Outlook 2010. We are running an older version here. I think only SP1 with no other incremental updates. Office is up to SP2. Also, one of the users I was working with could not access
the mailbox no matter what we tried but she can walk over to another workstation and open Outlook and access the very same mailbox so that pretty much proves its software related particularly with Outlook.
I cannot reproduce the problem on a workstation (XP) with a newer version of Outlook.
This has been wearing me out and I suspected the Update Rollup all long. Now I am confident as others are having the same problem. If you find out anything on how to fix this other than the steps above, let me know.

Windows Server 2008 R2 Standard "Certificate Authority Service" / Exchange Server 2010 EMC not starting and no AD connectivity for authentication.

Hello,
I am a new IT Manager at this company and need assistance big time. Their environment looks as follows:
Server 1. Domain Controller Server (Windows Server 2008 R2 Standard) running active directory.
Server 2. Email Server (Windows Server 2008 R2 Standard) running Exchange Server 2010 .
* Note. No back ups to work with aside from whats mentioned below.
DC had a virus infection causing a lot of issues on the shared network drives 2 days ago locking up all the files with a crypto ransom virus. Running Avast suppressed the infection. Had to recover the file shares which luckily had a back up.
The issue is that the Exchange Server 2 post this lost connectivity with the AD Server 1. Exchange Server 2 when launching EMC could not launch the console stating the following:
"No Exchange servers are available in any Active Directory sites. You can’t connect to remote
Powershell on a computer that only has the Management Tools role installed."
Shortly after I found that it is possible the EMC launcher was corrupt and needed to be reinstalled following another blog post. I deleted the exchange management console.msc per instructions only to discover I couldnt relaunch it because there was
no way how. So I copied another msc file that happened to be on the DC Server 1 back to Exchange Server 2 and got it to launch again.
Another post said that it might be an issue with the Domain Account for the Computer, so to delete it in the AD Server 1 only to find that rejoining it from Exchange Server 2 using Computer>Properties> Chage Settings > Change is greyed out because
it is using the Certificate Authority Service.
I tried manually re-adding the computer in AD and modeling permissions after another server in group settings but no go. After this I was unable to login to the Exchange Server 2 with domain accounts but only local admin, receiving the following Alert:
"The Trust Relationship between this workstation and primary domain failed."
I tried running the Power Shell tools on Exchange Server 2 to rejoing and to reset passwords for domain accounts as noted in some other blogs but no luck as the Server 2 could not make the connection with Server1 or other errors it kept spitting out.
I also during the investigation found the DNS settings were all altered on both the Server 1 and Server 2 which I luckily was able to change back to original because of inventorying it in the beginning when I started.
I need help figuring out if I need to rejoin the Exchange Server 2 manually by disabling the Certificate Authority Service (or removing the CA as listed here:
https://social.technet.microsoft.com/Forums/exchange/en-US/fb23deab-0a12-410d-946c-517d5aea7fae/windows-server-2008-r2-with-certificate-authority-service-to-rejoin-domain?forum=winserversecurity
and getting exchange server to launch again. (Mind you I am relatively fresh to server managing) Please help E-Mail has been down for a whole day now!

I recommend that you open a ticket with Microsoft Support before you break things more.

Any known issue reported for "Rollup 8 for Exchange Server 2010 Service Pack 2"

Hello,
Currently our servers are running with "Exchange 2010 SP2 RU7", we are planning to update the Rollup version to RU8 for SP2.
Is there any knows issues reported for "Rollup 8 for Exchange Server 2010 Service Pack 2" till now ? is it safe to update the RU8 ?
http://www.microsoft.com/en-us/download/details.aspx?id=41394

(1) I had to roll it back:
The rollup released Tuesday the 9th caused random problems with systems ranging from general slow down to operation failed errors. It didn’t impact everyone at once and seemed to take 48hrs for everyone to have a problem. Rolling
back the update and rebooting the server seemed to resolve the issue.
Issues reported before the general mailflow stopping for everyone:
Nothing major … an occasional operation failed when I hit send but, it will go thru after I hit the send button a couple of times.
A MICROSOFT OUTLOOK BOX APPEARS WITH A TRIANGLE WITH A ! INSIDE IT. THE MESSAGE SAYS THE OPERATION FAILED.
(2)
ANOTHER CODE APPEARED WHEN I TRIED TO SEND THIS E-MAIL SO I CLOSED OUTLOOK AND RE-STARTED OUTLOOK. THE MESSAGE READ, CANNOT CREATE THE E-MAIL MESSAGE BECAUSE A DATA FILE TO SEND AND RECEIVE MESSAGE CANNOT BE FOUND. CHECK YOUR SETTINGS IN THIS MICROSOFT
OUTLOOK PROFILE. IN MICROSOFT WINDOWS, CLICK CONTROL PANEL.CLICK USER ACCOUNTS AND THEN CLICK MAIL. CLICK SHOW PROFILE, AND THEN CLICK PROPERTIES.
When he tries to open an e-mail, he gets an error message.
If he tries to mark an e-mail unread, he gets a different message.

Processor requirments for Exchange Server 2010 roles

I am looking at migrating from Exchange Server 2003 to Exchange Server 2010. My exchange environment has 350 mailboxes. Can anyone tell me how much processing power will be required for each exchange role to run on VMware? I know Microsoft's recommendation is 1GB per core.

Hi Amyraghunath,
It's hard to give general guidance on sizing Exchange 2010 since it is heavily dependent on your specific configuration. The key number to use for sizing the Mailbox server role is to know the number of messages sent/received per day. That number will help you size CPU and memory for your Mailbox server which will ultimately drive the sizing for the other roles.
A good place to start is the following article: http://technet.microsoft.com/en-us/library/ee712771(v=exchg.141).aspx
That article describes the impact of messages sent/received per day has on sizing the Mailbox server and shows the math that is involved as well. Once you know how to size the Mailbox server, you can size the other roles as well.
You can also use the Exchange Mailbox sizing calculator here ( Exchange 2010 Server Role Requirements Calculator - Exchange Team Blog - Site Home - TechNet Blogs), though be careful with this because if you aren't sure what you're entering in here you could end up with incorrect results.
Finally, here are some other great links that should be helpful to you in sizing your Exchange 2010 environment on vSphere:
