Hi Folks,

sometimes you forget to delete the Exchange 2010 CAS Array Object with “Remove-ClientAccessArray” within the Exchange 2010 Shell while migrating to Exchange 2013.

After Deinstallation of Exchange 2010 the “Remove-ClientAccessArray” isn’t available in the Exchange 2013 Shell.

To remove the CAS Array Object open ADSI-Edit and go to configuration

Navigate to this path:

CN=Configuration,DC=DOMAIN,DC=LOCAL
CN=Services
CN=Microsoft Exchange
CN=EXCHANGE_ORG
CN=Administrative Groups
CN=Exchange Administrative Group (FYDIBOHF23SPDLT)
CN=Array
DELETE CAS Array Entry and wait for AD Replication

cas-array

Hey Folks,

after updateing a customers’ Exchange 2010 SP3 Server to SP3 Rollup 1 we got massive Problems with the ExchangeTransport Service.

The serivce crashed repeatedly and generated several Event log entries with the following IDs:

4999,10001,10002,10003,12028

The Exchange poison quee was filled up with normal mail traffic.

After uninstalling SP3 Rollup 1 from the HT servers the problem disappeared.

Cheers,

Chris

UPDATE:

My colleague Michael Miklis pointed out to me, that this behaviour is referred in the SP§ RU1 release article:

Known Issue

After this update is applied, there is an issue in which messages stick in a poison queue and the transport service crashes.

This issue is caused by a transport rule (disclaimer) that tries to append the disclaimer to the end of HTML-Formatted messages. When this occurs, messages are put in the poison queue and the transport service crashes with an exception. We are investing resources to develop a code fix. To work around this issue, you can disable or reconfigure the disclaimer transport rule.

I am often approached by clients on Exchange’s singel item recovery feature. Without tools you can only configure the single item recovery feature PowerShell. This article will provide an overview of the necessary steps.

Activation in Exchange 2010
Activate single-item-recovery for all users

get-mailbox -RecipientType ‘UserMailbox’ | Set-Mailbox -SingleItemRecoveryEnabled $true

Set the deleted-item retention for all databases to 30 days

Get-MailboxDatabase | Set-MailboxDatabase -DeletedItemRetention 30

Fetch deleted-item retention, database and server

Get-MailboxDatabase | ft name, server, deleteditemretention

Get an overview about mailbox, logon, size, deleted items filtered by city Hamburg

get-recipient  -RecipientType ‘UserMailbox’ -Filter ‘((City -like ”Hamburg”))’ | Get-MailboxStatistics | ft DisplayName,LastLogonTime,LastLogoffTime,TotalItemSize,DeletedItemCount

Recovery
Recover deleted items from user mailboxes

Mailbox export request

New-MailboxExportRequest -Mailbox “Discovery Search Mailbox” -SourceRootFolder “Folder of deleted Mail” -ContentFilter {Subject -eq “Subject of deleted Mail”} -FilePath \\FileServerName\C$\ExchangeRecovery\RecoveredMails.pst

If you got an error message that the command Search-Mailbox does not exist, simply close and reopen the Exchange Management shell

Import the messages to the user’s mailbox, use the following command:

New-MailboxImportRequest -Mailbox “Username” -TargetRootFolder “Recovered by Admin” -FilePath \\FileServerName\C$\ExchangeRecovery\RecoveredMails.pst

In the Exchange Management Shell, enter the following command:

Search-Mailbox “Discovery Search Mailbox” -SearchQuery “from:’Username’ AND Subject of deleted Mail” -TargetMailbox “Username” -TargetFolder “Recovered by Admin” -LogLevel Full -DeleteContent

Switch back to the client workstation and check if the message has disappeared from the Discovery Search Mailbox.

Open Outlook and review the new folders from the recovery processes.

Cheers,

Chris

Recently I had a problem while migrating a customers’  Exchange 2003 to MSX2010. The mailbox migration went well, and so we deleted all mailstorage groups on the Exchange 2003 Backend server.

After this we started to move the public folders on a Exchange 2003 Frontend server and triggered the “Move-All-Repicas” script on the Exchange 2010, too.

Nothing happened – no messages in the event log. After several attempts the customer tested to move the public folders on the original BE server and immediately appeared the error: “Error c1050000 MSexchangeIS – Profile is not configured”. (Thank you, Joerg;-))

After brief research, it turned out that this error occurs if on the public folders’ source server no mailbox storage group is configured.

After re-create a storage group and and information store mailbox replication worked as expected.

Cheers,

Chris

Earlier last year, we announced that Exchange 2010 Service Pack 3 would be coming in the first half of 2013. Later, we updated the timeframe to Q1 2013. Today, we’re pleased to announce the availability of Exchange Server 2010 Service Pack 3, which is ready to download.

Service Pack 3 is a fully slipstreamed version of Exchange 2010. The following new features and capabilities are included within SP3:

  • Coexistence with Exchange 2013:Customers who want to introduce Exchange Server 2013 into their existing Exchange 2010 infrastructure will need the coexistence changes shipping in SP3.NOTE: Exchange 2010 SP3 allows Exchange 2010 servers to coexist with Exchange 2013 CU1, which is also scheduled to be released in Q1 2013. Customers can test and validate this update in a representative lab environment prior to rolling out in their production environments as an important coexistence preparatory step before introducing Exchange Server 2013 CU1.
  • Support for Windows Server 2012: With SP3, you can install and deploy Exchange Server 2010 on computers that are running Windows Server 2012.
  • Support for Internet Explorer 10: With SP3, you can use IE10 to connect to Exchange 2010.
  • Customer Requested Fixes: All fixes contained within update rollups released before SP3 will also be contained within SP3. Details of our regular Exchange 2010 release rhythm can be found in Exchange 2010 Servicing.

In addition to the customer reported issues resolved in previous rollups, this service pack also resolves the issues that are described in the following Microsoft Knowledge Base (KB) articles:

I’ve spent quite a bit of time going through the new browser-based Exchange Administration Center (EAC), the replacement for the now aged Exchange Management Console (EMC) in Exchange 2013 to create content for Microsoft Exchange 2013 Inside Out. As I’ve gone through the various sections of EAC, I’ve noted where bits of functionality appear to be missing when compared to EMC. At the time of writing, the list of missing features is as follows:

  • You can’t send a message to a user from the console. This feature depended on an email client being available on the same workstation where EMC ran.
  • The ability to join the Customer Experience Improvement Program (CEIP) is removed. You can run some EMS cmdlets instead. Most people won’t realize that CEIP signup is gone.
  • The script that counted and reported the number of Client Access Licenses that need to properly license Exchange is no…
