I just came across a handy tool to calculate Return Of Investment (ROI) on Exchange deployment. Tool is developed by U-B Tech and available at free of cost to use.
Use U-BTech’s Exchange 2010 ROI tool to compare the costs of implementing Exchange 2003, 2007 and 2010 and try different cost variations including storage costs, hardware costs, licensing costs and more by just providing basic inputs.

You will get nice calculated comparative report in html file.
You can even customized the licensing and hardware cost.

When we install Exchange 2007, by default it install a self-signed certificate with one year validity. This causes a problem for the Admins when a year completes, specially when they are not much familiar with Powershell Cmdlets because self-signed certificate can be renewed with EMS cmdlets only.
However it is pretty simple to renew self-signed certificate and requires going through below 4 steps only.
- Get the list of Exchange Certificates with below cmdlet and note the ThumbPrint of the certificate which is about to expire or already expired but still some services are attached with it.
Get-ExchangeCertificate | FL ThumbPrint, isSelfSigned, NotBefore, NotAfter, Services
- Create a new certificate for the expiring certificate.
Get-ExchangeCertificate “ThumbPrintOfExpiringCertificate” | New-ExchangeCertificate
- When you create new certificate, by default it is enabled for POP, IMAP and SMTP services based on old certificate properties but if old certificate is enabled for IIS services too, then you need to enable IIS service for new certificate manually with below cmdlet.
Enable-ExchangeCertificate -ThumbPrint “ThumbPrintOfNewCertificate” -Services IIS
- Remove old certificate since it is no more required.
Remove-ExchangeCertificate –ThumbPrint “ThumbPrintOfExpiringCertificate”
So what’s new with Exchange 2007 Service Pack 2?
Fresh installation of Exchange 2007 Service Pack 2 issues a self-signed certificate with 5 Years of validity. Yes, so you don’t have to renew self-signed certificate every year. This is a big relief for small organizations when they don’t use a certificate issued by anyone of the trusted 3rd party CAs.
Note: Self-Signed certificate validity doesn’t change in case of upgradation of existing Exchange 2007 or Exchange 2007 Service Pack 1 Server to Exchange 2007 Service Pack 2.
Since this change is already implemented in Exchange 2007 Service Pack 2, hopefully we can expect the similar behavior in Exchange 2010 by the time it RTMs !?!?!
Another goodies for Exchange 2007 Service Pack 2, Shell Help file. The Microsoft Exchange Server 2007 Exchange Management Shell Help file helps you use cmdlets in the Exchange Management Shell to perform day-to-day administration of Exchange 2007. You can view help in the Exchange Management Shell by using the Get-Help cmdlet. This Help file applies to the Microsoft Exchange Server 2007 Service Pack 2 (SP2) version of Exchange Server 2007.
Download standalone version of Microsoft Exchange Server 2007 SP2 Help file, an offline copy of Exchange Server TechNet in CHM format.
The Exchange Server 2007 SP2 Help can help you in the day-to-day administration of Exchange. Use this information to guide you through Exchange Server 2007 SP2 features, tasks, and administration procedure.
