Any solution for this alert, how to rectify it, but OWA is running perfect for all users.

Hi,
Sorry for the late reply.
Do we have Exchange 2010 coexistence?
If it is the case, I know the following known issue:
Release Notes for Exchange 2013
http://technet.microsoft.com/en-us/library/jj150489%28v=exchg.150%29.aspx
Please note the "Exchange 2010 coexistence" session.
If it is not related to our problem, please check the IIS log.
If there is any detailed error code, like 401.1, 401.2, please let me know.
Hope it is helpful
Thanks

Exchange 2013 CU2 to CU3 OWA now redirects to IIS page

so i did the the update from Exchange 2013 CU2 to CU3 last night and i am unable to access OWA. when i go to the site i initially received a 403 forbidden error but i cleared out the require SSL, which somehow got re-enabled, and now it redirects to the
IIS 8 page.
In IIS it seems like the redirect values for default web site got cleared away. I put in the address that was previously there and then e-mail for the whole company goes down after an IIS reset. In the default web site i entered to redirect to https://mail.contoso.com/owa
like how it was before but that doesn't work.
any ideas/feedback would be great!
Thanks!

I guess you are running a multirole server.
Did you try removing the OWA virtual directories - for both Default Website and Exchange Back End site with:
#Replace ServerName
Remove-OwaVirtualDirectory "ServerName\owa (Default Web Site)"
Remove-OwaVirtualDirectory "ServerName\owa (exchange back end)"
and re-creating them again with:
#Replace ServerName & mail.domain.com
New-OwaVirtualDirectory -InternalUrl "https://ServerName/owa" -ExternalUrl "https://mail. domain.com/owa"
New-OwaVirtualDirectory -InternalUrl "https://ServerName/owa" -ExternalUrl "https://mail. domain.com/owa" -WebSiteName "Exchange Back End"

Alert: Health Set unhealthy - Clustering

We have SCOM 2012 R2 setup to monitor our Exchange 2013 CU5 enviroment and we have gotten this error message about our Clustering going in to an unhealthy state a couple of times. We have checked the FSW and everything seems OK on its end. I
cannot find much out there on this message, so any help would be greatly appreciated:

To add some additional information, when I look in Failover cluster manager this is what I see. I know when we setup the servers the correct FSW information was being displayed.

Hi,
According to the error message, "Offline is offline. Please verify that the Cluster service is running on the server.",
I suggest double check whether the Cluster service is running as well. If not, please restart the service manually to verify whether this issue exists.
Please also refer the blog below to double check whether the FSW online:

If there is nothing abnormal on the Exchange server, it seems an issue on the SCOM side. Please contact SCOM Forum for help so that you can get more professional suggestions. For your convenience:

Outlook 2010 SP2 - Error when editing shared calendar: Post Exchange 2013 CU2 Migration

Hi there,
I have a strange comportment with Outlook 2010 SP2 and Exchange 2013 CU2 and i really need your help.
Frequently, when an user (who has the good permissions for) want to edit a shared calendar (edit a meeting or add one), he has this error message:
" Cannot display the folder. Your server administrator has limited the number of items you can open simultaneously. Try closing message you have opened or removing attachments and images from unsent messages you are composing "
I see anything in the Exchange server event log but i have each time, an error message in the client event log:
" Microsoft Office14 Alerts ID 300"
Everything work very well with Outlook 2013.
Many thanks in advance for your assistance, and I am looking forward to reading from you.

Hi,
According to your description, the issue is related to your Office 2010 client.
And the issue can be resolved by installing the Microsoft Office 2010 Deployment Kit.
Here are the steps you can refer to :
1. Open a command prompt with administrative permissions.
2. Browse to the directory that contains the Offvirt.msi.
3. At the command prompt, run the following command:
msiexec /i OffVirt.msi [licensing flags]
You must enter a correct licensing flag in the following list to correctly configure the Deployment Kit. Otherwise, functionality may be incorrect.
For more information, you can refer to the following article:
http://blogs.technet.com/b/virtualworld/archive/2010/07/07/microsoft-has-encountered-an-error-with-licensing-and-will-need-to-close.aspx
If you have any question, please feel free to let me know.
Thanks,

Is the certificate for Web Management Service (WMSvc) missing?
If so, then you need to create a new one and assign it to the feature "Management Service" in IIS.

Exchange 2013 CU2 will not install, Exchange is now in an unuseable state.

I have downloaded Exchange 2013 CU2 and attempted to install it from a local drive. Exchange 2013 is installed on a Server 2012 Standard VM in Hyper-V. I ran the two following commands before trying to install
setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms
setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms
Upon trying to run the installer, I recieve the following error.
Error:
The following error was generated when "$error.Clear();
                    & $RoleBinPath\ServiceControl.ps1 EnableServices Critical
                " was run: "AuthorizationManager check failed.".
During my first install attept, the error was on step 4 of 15. I have tried to rerun the setup with no luck. I noticed the installer leaves all the Exchange services disabled, as well as winmgmt, remoteregistry, w3svc, iisadmin. These four services
are the critical services the errors refer to. I have verified my execution policy is correct
PS C:\Windows\system32> Get-ExecutionPolicy -list
Scope
ExecutionPolicy
MachinePolicy
Unrestricted
UserPolicy
Undefined
Process
Undefined
CurrentUser
Undefined
LocalMachine
RemoteSigned
Upon trying to rerun the setup, I have ran the following commands in order to start the critical services manually
Get-Service-name
winmgmt,
remoteregistry,
w3svc,
iisadmin
|
set-service -startuptype
automatic
Get-Service-name
winmgmt,
remoteregistry,
w3svc,
iisadmin
|
Start-Service
No matter what I do, the Exchange 2013 CU2 installer seems to fail. I'd appreciate any possible help with this.
Thanks,
Chris

Mails were deleted automatically from inbox and sent items, even in deleted items in Exchange 2013 CU2

Dear all:
I encountered a problem and needs to be solved.
We runs Exchange 2013 CU2, and some users told me that their mails in sent items and inbox were automatically delivered into "deleted items", especially in last two weeks or yesterday.
The users said they cannot delete so many mails at one time. And now I found one user's mails in "deleted items" were also deleted this morning.
I don't know whether it was bug or not in exchange 2013 cu2, and how to solve this problem? Thanks for any help.

Hi koiso,
Are there any commons among problematic users or deleted emails? For example,
they are on the same database
they have delegate settings
they are using mobile phone to sync emails
At the same time, I'd recommend you enable Mailbox Audit Log for the problematic users. For your reference:

FrontendTransport health set unhealthy (OnPremisesSmtpClientSubmissionMonitor)

FrontendTransport health set unhealthy (OnPremisesSmtpClientSubmissionMonitor) - The client submission probe failed 3 times over 15 minutes.
Seems like these alerts have started comming for some of the servers, where mailbox and CAS role is installed together. when i cehcked the queue, all seems to be fine. Performed the below mentioned steps, but the issue didn't fixed:
1. invoke-monitoringprobe" command doesn't work.
2. Have restarted "health manager service" didn't work.
Still the alert value is in uhealthy state, have anyone come across the same issue, if so, can you share what are the steps that we have take?
Your answers are much appreciated!

Hi,
Please check the Monitor Result and Probe Result in the following path and see if there is any related message.
Event Viewer\Applications and Services Logs\Microsoft\Exchange\ActiveMonitoring\ProbeResult( or MonitorResult).
Based on your description, everthing works well except this alert. However, there is a way to hide the alert by overriding the monitor using the command below:
Add-GlobalMonitoringOverride -Identity "FrontendTransport\OnPremisesSmtpClientSubmissionMonitor" -PropertyName Enabled -PropertyValue 0 -ItemType Monitor -ApplyVersion "version"
Hope this is helpful to you.

How is called the Services "OpsMgr Health Service" in the SCOM 2012 and Client machine?

Hi,
Can anybody tell me how is called the Services of OpsMgr Health Service in the SCOM 2012?
I have installed the agent of scom2012 on my client computer. But I dont find any agent called "OpsMgr Health Service" on the Client machine?
Regards

Hi
If you look in the services.msc window then it is listed as the System Center Management Service. This is the display name.
The actual service name is HealthService

Exchange 2013 CU2 OWA Redirection not working

Hi,
I installed Exchange 2013 RTM in existing environment with Exchange 2010 Sp3 in our test environment. After installing Exchange 2013 RTM I checked when I access OWA using Internal URl it redirected to Exchange 2010 CAS server's Internal URL and I was
able to access Exchange 2010 mailbox.
I upgraded to CU2 and now Exchange 2013 internal URl not re-directing it to Exchange 2010 mailbox anymore. I checked all the settings on virtual directories and made sure that FBA authentication is selected. It is a test environment and I just wanted
to test the re-direction in co-existence environment using Internal URL. It should work out of the box but not sure what happened. There was no issue in CU2 instllation.
Exchange 2013 CAS and mailbox roles are on separate servers. Same with Exchange 2010. There is no certificate 3rd party certificate install on CAS servers since it is a test environment.
Not sure what else can I check.
I appreciate if any help I can get.
Thanks,
Regards

I have been seeing issue where 2013 OWA was not re-directing to Exchange 2013, as mentioned on top of this thread. After spending days over it.
Finally it resolved for me after doing the following: -
Go to CAS 2010 IIS
OWA directory -> Authentication -> Windows Authentication -> Add provider
Negotiate and NTLM.
Although, now when I click on "Options" once OWA is redirected to 2010. ECP does
not work. It just open up ECP page but no link works not even sign out. I had to click back on the browser's back button go get back to main OWA mail page.
OWA and ECP directory settings are same. I have checked several times.
Thanks,
Raman

Out of office replies in Exchange 2013 not working for external recipients

Hi,
Few days ago a couple of company workers went to vacation. They set up OOF automatic replies in OWA 2013. However automatic replies are not working for external recipients (outside of company). Internal users (company users) receive OOF notification.
I'm using smart host in sender connector configuration (SMTP server of internet provider) to deliver emails. Any clues about this problem ? Please find below part of the transaction log. For testing purposes i set up administrator account
to be on vacation.

Hi Informus,
Please check if it is allowed in AllowedOOFType of the Remote Domain *
In Exchange 2013, the only way to see or change the current configuration for automatic replying and forwarding to the Internet is via the Exchange Management Shell (EMS) with PowerShell commands.
To get the currently configured Remote Domains, use:
Get-RemoteDomain
Name                           DomainName
AllowedOOFType
Default                        *
External
Get-RemoteDomain Default | fl AllowedOOFType, AutoReplyEnabled, AutoForwardEnabled
AllowedOOFType     : External
AutoReplyEnabled   : False
AutoForwardEnabled : False
To change the settings, use the Set-RemoteDomain command.
Enable automatic replies
Set-RemoteDomain -AutoReplyEnabled $true
Enable automatic forwards
Set-RemoteDomain –AutoForwardEnabled $true
Enable OOF for Outlook 2003 and previous (for Exchange 2007 and 2010 support)
Set-RemoteDomain –AllowedOOFType $ExternalLegacy
To change all these properties at once, you can use:
Set-RemoteDomain Default -AutoReplyEnabled $true –AutoForwardEnabled $true –AllowedOOFType $ExternalLegacy
Note:
Valid settings for the AllowedOOFType property are:
External
This is the default and only allows for the new style OOF messages as introduced in Outlook 2007.
ExternalLegacy
This settings allows for both the new style and old style OOF messages and needs to be set if you want to enable external OOF support for Outlook 2003 as well.
None
This setting doesn’t allow for the use of OOF messages at all (both internal and external).
InternalLegacy
This setting only allows for internal OOF messages to be sent for all Outlook versions.

Satyajit

Exchange 2013 ECP redirects to OWA

Dear Collegues,
after that I ve installed Exchange 2k13 on my win server 2012 std, I am not able to reach the EAC, when I tried to enter this URL: https://servername/ecp or https://servername/ecp?ExchClientVer=15 it redirects me always to OWA. I ve also tried this solution
http://www.telnetport25.com/2012/11/quick-tipcreating-an-icon-on-the-desktop-for-the-exchange-2013-eac/ with no effect, also this http://lyncdude.com/2013/02/07/cannot-access-exchange-contorl-panel-ecp-in-exchange-server-2013/, but what really strange is,
that my powershell cant recognize for ex. this syntax - Get-owavirtualdirectory | fl or Set-owavirtualdirectory -identity “owa <Default Web site>” -FormAuthentication:$true at all.
I am really confused with all of that Exchange 2k13 installation and configuration, from the beginning there are so many problems.
Please can anyone help me?

Hi,
To enable the system mailboxes, I’d like to confirm how you disable them: delete the mailboxes from the Exchange management tool or delete the account from the ADUC.
For more detailed steps to enable the system mailbox, you can refer to the following article:
http://social.technet.microsoft.com/wiki/contents/articles/6874.how-to-recreate-system-mailbox-federatedemail-discoverysearchmailbox-in-exchange-2010.aspx
For the redirection issue, I recommend you check the result if you login with a admin account: check it’ OWA or EAC.

Out of nowhere...literally this started happening to our standalone Exchange server / Domain Controller
Operating System: Microsoft Windows Server 2012 Standard
Problem Child: Microsoft Exchange Server 2013
Error: When i try to login to the OWA or ECP i receive the listed errors above.
OS and Exchange installed on C:\
Mailbox Databases installed on D:\
Mailbox Logs on E:\
Outlook is still working for the end-user, but Outlook Web Access, ECP and all other features required to make this server manageable are failing. I can access the login screen, though at:
https://<servername>/owa
or
https://<servername>/ecp
I have tried reset of virtual directories. Tried IISRESET /NOFORCE after this, but no success.

Hi MRXennix,
Base on my research, the issue is caused by corrupted Killbit.xml file on "ClientAccess\owa\15.0.xxx.x\owa2\ext\killbit".
I recommend you refer to the following method to solved the issue:
1. Remove the Killbit.xml file and restart IIS
2. Install the latest CU builds of the exchange 2013.

Migrating from 2010 windows nlb cas array to exchange 2013 using netscaler for HLB

i currently have exchange 2010 sp3 setup as follows
2 cas/ht using windows nlb for array.internal.com as the nlb name
2 mailbox servers using 1 dag for replication between them.
I would like to stand up 2 new CAS 2013 sp1 servers(2012 r2) and use our netscaler hlb to load balance and do ssl offloading.
id like to use the hlb to load balance and ssl offload all possible traffic not just owa, i.e. activesync etc.
the netscaler is running version 10.5.
does anyone have any thoughts on how to perform such a migration?
id like to make this as seamless as possible for the user, so no owa name change or anything like that.
thx in advance for any help.

Exchange 2013 CAS cannot be managed effectively without an Exchange 2013 mailbox server since the CAS won't run the Exchange 2013 management tools without it. Your Exchange 2013 servers should simply have both roles. There are few cases where
splitting the roles has any business value.
If what you're planning to do is within the same forest and organization, then it's a "transition", not a "migration". What you are asking to do is easy. Build the Exchange 2013 servers, configure load balancing, test
access, and then switch the DNS records to point to them.
Personally, I would skip the SSL offloading. It's my opinion that it makes the solution more difficult to troubleshoot without providing any real benefit.
