Microsoft Exchange couldn’t find a certificate that contains the domain name mail.smtp25.org in the personal…. EVENT ID 12014

Filed under: General — telnet25 @ 3:18 pm

Error:

Microsoft Exchange couldn’t find a certificate that contains the domain name mail.smtp25.org in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector HTS-IronPort with a FQDN parameter of mail.smtp25.gov. If the connector’s FQDN is not specified, the computer’s FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.

Solution

Open EMS

Get-ExchangeCertificate | FL

Filed under: General — telnet25 @ 9:07 pm

Below  article is taken from MSExcahnge team site, if you have not seen it yet , here it is.

Exchange 2010 is Code Complete Cryingand on its way to General Availability

We are happy to announce that Exchange 2010 is Code Complete!  Our senior leadership team has signed off on the final code, and it has been sent to our early adopters for one final look before its public release. This Release to Manufacturing (RTM) milestone means we are on our way to general availability and the launch at Tech·Ed Europe 2009 (http://www.microsoft.com/europe/teched/) in early November.

For those of you attending Tech·Ed in Berlin this year, be sure to check out the Unified Communications track, which is packed with technical content on Exchange 2010. And be sure to visit us at the Exchange product booth in the Exhibition Hall and let us know what you think of the product. Crystal Flores, who interviewed some of you on video at Tech·Ed North America earlier this year, will be on-hand in Berlin in a few weeks, armed with a camera and interview questions.  A group of us are also marching to Las Vegas for Exchange Connections the same week where our fearless leader Rajesh is giving the keynote.

Exchange implementation over VM environment

Filed under: General — telnet25 @ 3:48 am

This was asked on the MS forums and I tried to pass on some of my positive experience and end up writing long answer and of course decided to post it here , hoping I could give some positive feed back to some of you out there wondering how exchange would be performing on VM environment.

Dave, I understand you have your own reasons to go for SCC and wondering if CAS , HTS roles would be a good idea placing on virtual environment and my previous implementation experience might be able to answer your questions, hopefully (-:

I had to go for SCC for my own reasons as well, not the limitations but SAN appliance was offering perfect DR solutions (NETAPP) Snapmanager and I was extremely comfortable going for SCC for so many reasons I will just mention couple of them, Netapp has never failed me over 10 years, in multiple very large implementations and Snapmanager offered perfect DR solutions ( it does log shipping and just like CCR) and replicate SAN data to San data.

So I ended up placing two Hub servers on VM, two CAS servers on VM, and  two ISA servers, for redundancy, each server was placed on separate VM farm, so that if one VM farm goes down the mail infrastructure would work without any interruption. I used as mail gateways 2 Ironport on toe different data center and created two sent connectors one with high cost for redundancy. Both Ironport published outside to public DNS for redundancy .Although traditional DNS provides round robin response, in reality it is up to sender who to send the mail too and one thing I did not implement was road balancer in front of Ironport like F5 to be able to provide true redundancy (-: , ran out off $$$$

So VM servers has been working with no glitch over months, mail uptime is 99.9 , I have been extremely pleased with Exchange servers running on VMware ( HTS, CAS) no issues at all. Same goes for SCC , it has been running flawless fail over with 08 server is much better in my opinion, and maintenance is the most part I love about SCC.

This wasn’t the first time I placed Exchange servers on VM farm we have been doing this since Exchange 2003 (except mailbox server) we placed exchange 2003 servers in large environments  40.000 + mailboxes and they have been running with no issues over years (almost 6 years) ,

honestly I have not seen one single issue, but please remember all these implementation have been followed by MS best practices ( memory, HD, CPU etc.) except the VM part (-:

Good luck to you on your implementation

In addition Exchange 2010 is almost out, as I said so many times to me Exchange 2010 is the ***MOST ADVANCE*** version of messaging application ever, and due to critical changed have been done to the application itself , I strongly recommend everyone out there start planning to place Exchange 2010 in your business, it really wont be brainer to figured out business reasons and benefits running your messaging environment with next generation messaging application with incredible changes and stunning performance not to mention full redundancy out the box (-:

Many thanks to Exchange team for incredible hard work and providing us the best messaging application.

Regards,

Ocd

How to set & Change sending and receiving mail size in Exchange 2007

Filed under: General — telnet25 @ 4:37 pm

Two ways to accomplish changing default size limits if you are on SP1 or later you can use GUI or Shell

  • Organization Configuration
  • Hub Transport
  • Global Settings tab
  • Transport Settings
  • properties

1024 X 20 = 20480

10 meg 10240
20 meg 20480
30 meg 30720

  Set-TransportConfig –MaxReceiveSize 40mb –MaxSendSize 40mb

This CA root Certificate is not trusted. To Enable trust, install this certificate in the Trusted Root Certification Authorities store.

Filed under: General — telnet25 @ 4:32 am

On previous article we talked about , certificate warning

Information you exchange with this site cannot be viewed or changed by others. However, there is a problem with the site’s security certificate.

image 

The errors was causing by expired internal certificate on the CAS server or servers, as the limitation of internal issued certificates, ( expire in 1 year) we need to renew the expired certificate.

here is the link for more information

image

Here is summary how to deal with this situation

  • Get-ExchangeCertificate | FL  ( to see the status of cert installed and the thumbprint
  • Get-ExchangeCertificate -Thumbprint 56BB128980C53883BBF09AA0281FBC6471FB04FE | New-Certificate

**** you need to place your thumbprint

  • Get-ExchangeCertificate | FL  ( one more time to see the certs)

At this point you will see two of them , pay attention one is “Valid” one is not, it is Invalid.

image

you want to remove the Invalid one by typing

  • Remove-ExchangeCertificate –thumbprint 56BB128980C53883BBF09AA0281FBC6471FB04FE

Dont forget again the replace the correct thumbprint

Now you might need to enable the new cert with services

  • Enable-exchangecertificate -services IMAP, POP, UM, IIS, SMTP -Thumbprint DBA3601A10DF90E0F00462C03940C90B8BA87292

last time to make sure issue

  • Get-ExchangeCertificate | FL 

verify the Cert is valid and correct services are enable to use this internal cert.
