Using Secondary Email Address to Send Emails in Exchange 2007

Posted by Milind Naphade on 19/06/2009

This is just a work around and not a standard method. Broken rules on transport server may break the complete function.

Due to design limitations outlook and exchange together wont allow to send emails using the secondary email address on some user account. There are some third party utilities like IvaSoft which will allow to use secondary email address as a primary or to send emails. Here I am explaining the way to use Exchange Server 2007 features to achieve this.

In a scenario; user Administrator has an his primary email address as administrator@cassicrm.com and secondary email address as jsmith@contoso.com . For business reason Administrator needs to be able to send emails using both email addresses however this wont be possible due to restrictions in Exchange design. Here are steps to work around this problem;

1. Remove email address jsmith@contoso.com  from user account Administrator.

2. Create a new in AD using ADUC and mail enabled user account using EMS or EMC. Make sure the removed secondary email address from Administrator account is used as a primary email address on new user.image

3. Use ADUC again to assign Send As permissions to Administrator user account on newly created user account. Here, you need to consider that you will be using this user account to send emails so you may not want to have the display name different than the user having send as permissions on this user account. In stead of creating a new user account named Joe Smith the display name should be Administrator or the name of the user you are assigning Send As permissions to.

4. Configure a transport rule on HT to have emails redirected to administrator@cassicrm.com once an email is received for email address jsmith@contoso.com

5. Use outlook to send as new email address. Now in this step when you create the user account you need to make sure that the new user’s display name need to be same as the Administrator’s display name in GAL.

6. Check if the recipient received an email sent using alternate email address.

This work around will work for Exchange 2003 as well but with a limitation that recipient of email sent using secondary email address wont be able to reply as there is no mechanism in Exchange 2003 that can understand where to put the received email.

Exchange 2010 EMC and Certificates Management Part – 2

Posted by Milind Naphade on 17/06/2009

This is the second part of the blog entry Exchange 2010 EMC and Certificate Management Part – 1 in the previous post I wrote about creating a certificate request and the limitations of the new certificate request wizard. In this part we will be looking at obtaining a new certificate and then installing it on the server.

To complete installing a new certificate on your Exchange Server 2010 server you first need to obtain a certificate from CA within your organization or from a third party CA. As stated in last post the New certificate wizard generates a request in a .req file.

1. To obtain a certificate from a third party CA or your internal CA, your first need to copy the contents of the .req file and paste it to the web console of your certification authority. For my internal Enterprise CA the picture looked like below. Please see carefully that the Certificate Template used for this certificate request is Web Server.

2. Once you are done with above interface by pasting the contents of .req file and choosing a correct template you will be presented with another page in your browser to download the certificate. This interface may vary depending upon the configuration of your CA. You may need to wait till the certificate is approved and issued by CA administrator if configured so. You can now download the certificate in DER encoded format or Base 64 encoded format and save it to some location on your desktop or server. You will also need to download the whole certificate chain if the issuing authority is not a trusted CA by your server.

image

3. Now, as you have downloaded the certificate to the server. You will need to complete the pending certificate request in your EMC. Select the complete pending request by right clicking on the pending certificate request in EMC.

image

4. A new interface asking you the path to the certificate will pop up. This wizards will ask the location for newly downloaded certificate. Click on the Browse button, select the newly downloaded .cer file and click on complete button.

image

5. You may recall, Exchange 2007 to have the imported certificate to be enabled before it can be used actually used exchange services. E14 is not an exception to it but you don’t need to use Enable-ExchangeCertificate this time. You can do it using  GUI easily. Now that you know, you have a new certificate imported correctly. You need to assign it to the services those will be using it.

Again, locate the new imported certificate in EMC and right click on it. Select Assign Services to Certificate… from the context menu.

One quick difference you may notice between the step 3 and now. That is the certificate status. It changes from Pending to Valid and icon in front of the certificate gets blue colored check mark on it.

image

6. Assign Services to Certificate… will list the services on a window those will be assigned to use this certificate. Select the services you want to use this certificate with and click on Assign button. In my case I did not have the UM role installed on the server so the Unified Messaging check box is grayed out.

image

7. You may notice a pop up asking your consent to assign this certificate to SMTP service on the server as the default certificate will be replaced if you have selected Simple Mail Transport Protocol to use the new certificate in step 6. Click Yes and your default self signed certificate created and assigned to SMTP during server  install will be replaced with new one.

image

Click Finish in the wizard and you are done.

In some cases you may end up with a warning message; warning you that this certificate will not be used for TLS connections. Something like below:

image

Here you need to really understand the configurations you choose at the time of new certificate request. If you want to use this new certificate for a connector which provides a TLS connections, you will have to mention that during the New Certificate Request Wizard.

 

Few things to note:

  • You must make sure that you have chosen the option to use new certificate for TLS connections during the request generation.
  • You must have the root CA and the entire certificate chain installed your Exchange Server as well as clients if you are using your internal CA for new request processing. Outlook as well as Outlook Anywhere and other web based services may be affected otherwise.
  • You must back up the certificate as soon as it is enabled on the server. I will write about it in Part-3 of this series.
  • I recommend backing up and removing any old certificate from the server as soon as the new certificate is active and fully functional.

Microsoft says no to 32 bit management console for Exchange 2010

Posted by Milind Naphade on 12/06/2009

I just came across a very good post by Paul Robichaux on Windows IT Pro under Exchange and Outlook section.

Paul discussed the demand versus availability of Exchange Server 2010 32 bit management tools very well in his post.

Bottom line of the post talks about zero expectations to see a 32 bit management console for Exchange Server 2010. Only Microsoft can tell how difficult is it for them to write a 32 management console code.

Personally, I would do a favor for a whole new x64 architecture offering a more memory addressing capabilities and performance. Yes, it does include cost to upgrade the hardware and software both but sticking back to legacy versions of hardware and software holds you back from upgrading your skills yourself.

Companies do have budgets for their IT infrastructures and may not tend to spend more money towards upgrade. But an upgrade may also help the heldesk and support teams to perform their jobs easily and much faster than they used to do. Normally, an Exchange support engineer needs to have a well equipped computer with troubleshooting tools where he/she may also need to work with some tools which demand more memory and high performance systems.

Also, if you are favoring to have a 32 bit Exchange 2010 application for your test labs then you probably need to understand that testing a performance of application on a 32 bit platform will be drastically different than having it tested on fully functional 64bit platform.

Read more about this story at Exchange 2010: No 32-Bit for You

Considering all above aspects and few more highlighted by Paul in his article probably many people may think of changing their thoughts on demanding a 32 bit management tools or the whole software for test labs.
