How to install a certificate in Exchange 2010 using an Internal CA

Hi all,
we can install an Active Directory Certificate Services in windows server 2008, in order to configure an Internal PKI infrastructure.After that you will be able to submit server certificates for your Exchange 2010 environment, bear in mind that you will need deploy an installation of your Root CA certificates in your machines in order to trust and avoid the certificate pop up message,

Once you have your PKI infrastructure created (one Enterprise CA is enough), go to your CAS server

[PS] C:\>Set-Content -path "C:\Cert\cert.req" -Value $Data[PS] C:\>$data=New-ExchangeCertificate -GenerateRequest -SubjectName "c=CA,o=Company,cn=webmail.company.ca" -DomainName we

Chile ...no te olvides !!!! DST Patch for Windows Operative Systems...

Just a reminder.. for Chile,, we are close to 2nd Saturday of March

The December DST CU contains 2011 adjusted DST start and end-dates for the following timezones:

·    Israel Standard Time
·    Morocco Standard Time
·    PacificSA Standard Time
·    Samoa Standard Time
·    Syria Standard Time

Important This update supersedes and replaces update 2158563, which was released in September 2010. This update also includes additional time zone changes made after update 2158563 was created.

If you have already deployed update 2158563, read the descriptions of the specific time zone changes that are addressed in this article to determine whether you must deploy this update immediately. If systems are not directly affected, you can schedule deployment at the next available opportunity.

We recommend that you deploy the most current Windows cumulative time zone update to guarantee the consistency of the time zone database on all systems.

  • Before you apply the update that is described in this article, be aware of potential issues that may affect Microsoft Outlook.
    For more information about these issues, click the following article number to view the article in the Microsoft Knowledge Base:
    931667  (http://support.microsoft.com/kb/931667/ ) How to address time zone changes by using the Time Zone Data Update Tool for Microsoft Office Outlook
  • If you are running Microsoft Exchange Server in an Information Technology (IT) environment, you must take additional measures to guarantee the correct operation of Exchange Server.

    For more information about the Exchange daylight saving time (DST) update, click the following article number to view the article in the Microsoft Knowledge Base:
    941018  (http://support.microsoft.com/kb/941018/ ) How to address daylight saving time by using the Exchange Calendar Update Tool
  • Cumulative time zone updates contain only data that has changed for a specific region or that was added to maintain parity with other operating system versions. Therefore, if a time zone key is deleted, some original values may not be restored after you apply the cumulative zone update.
    We do not recommend that you delete any registry keys that are related to time zones. On a computer that has incomplete time zone keys, first restore the time zone keys from a known good backup. Then, apply the update.

Gracias amigos chilenos!!


Error: “Couldn’t find the Enterprise Organization Container” when Creating a New Mailbox Export Request

Hi all,
this is a new cmdlet from Exchange 2010 Sp1, that allow you to create a PST from an active mailbox. First of all you must create a share folder with the below permissions at NTFS and Share level for the Exchange Trusted Subsystem group

After that be sure if your account has the necessary permissions or create a New role for that

Add your user to this role

run the command
