Filed under: General — telnet25 @ 2:38 pm

If you are using internal non routable FQDN names such as Server1.smtp25.local, server2.smto25.local, etc.  with in your certificate they are set to be “ not trusted” after November 1 2015.  It means you have to abandon them from your certificate. If you have these none routable internal FQDN;s within your current certificate you may wish to look into how to get them out before November1, 2015.

After November1, 2015 Certificates for Internal Names Will No Longer Be Trusted

In November 2011, the CA/Browser Forum (CA/B) adopted Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates that took effect on July 1, 2012. These requirements state:

“As of the Effective Date of these Requirements, prior to the issuance of a Certificate with a Subject Alternative Name (SAN) extension or Subject Common Name field containing a Reserved IP Address or Internal Server Name, the CA shall notify the Applicant that the use of such Certificates has been deprecated by the CA / Browser Forum and that the practice will be eliminated by October 2016. Also as of the Effective Date, the CA shall not issue a certificate with an Expiry Date later than 1 November 2015 with a SAN or Subject Common Name field containing a Reserved IP Address or Internal Server Name. As from 1 October 2016, CAs shall revoke all unexpired Certificates.”

Install CU1 Exchange 2013

Filed under: General — telnet25 @ 12:22 pm

Here is the link and list of stuff you need to know before kicking off CU1 on Exchange 2013 servers. Nothing is major at first look,  the order to install updates has changed, since the business logic moved into MBX role this time we start from MBX role and go to CAS server,  if CAS is sitting on separate server in your environment.

I think most of deployments in E13 will be all in one and separation will less or not make much sense when rolling the dices.

  • Upgrade your Exchange 2013 server roles in the required order. First, upgrade Mailbox servers and then upgrade Client Access servers.
  • After you install a cumulative update, you must restart the computer so that changes can be made to the registry and operating system.

http://technet.microsoft.com/en-us/library/jj983803(v=exchg.150).aspx

Open CMD with administrator privileges on the E13 MBX server

run the fallowing command from CU1 binaries directory, the install will take time.

E:\Cu1>setup.exe /M:upgrade /IAcceptExchangeServerLicenseTerms

Filed under: General — telnet25 @ 1:23 pm

If you are managing Office 365 Exchange hosted mail systems and wish to connect to PS from your PC here are simple steps to get the work done. The remote PowerShell will provide you real easy way to manage your SMTP organization.

In this Example:

Office 365 SMTP domain we will connect too is @messagetalk.onmicrosoft.com and I am going to use my User name which has administrator privileges, odedeal@l@messagetalk.onmicrosoft.com

From administrator PS

  • Open PS with Administrator privileges
$LiveCred = Get-Credential

image

  • Run fallowing command ( don’t make any changes ) copy and paste into PS window.

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection

image

  • Next run this PS
Import-PSSession $Session

image

image

Now we are connected we can see our mailboxes etc.

image

If we look from GUI we have same users , we can use GUI to manage these users now as well as PS from our management PC

image

Once we are done we can close the PS session with fallowing PS command

Remove-PSSession $Session
