MS Exchange Information Store Service not starting after upgrading Exchange 2007 SP1 to SP3

I was working on Exchange 2007 SP1 to upgrade it to SP3. I upgraded the server with SP3 without any issue and restarted the server. After the restart i found that MS Exchange Information Store service is not started. I tried to start it manually but it failed with event id 5000.
As per the support article but in my case it wasn't the issue.

I was getting the error message:
Unable to initialize the Microsoft Exchange Information Store service. Failed to find the working directory parameter from the registry - Error 0x80004005.

After doing little bit of research i found that i have to make changes in the registry.
I went to the registry Editor on the server:
Under this Registry Key:
Add a new String Value and call it "Working Directory"
Enter the path for the working directory C:\Program Files\Microsoft\Exchange Server\Mailbox\MDBTemp

Note:You need to make sure that you have the right name of the String Value and the location i.e C:\Program Files\Microsoft\Exchange Server\Mailbox\MDBTemp

After making the change, restarted the Exchange Server and MS Exchange Information Store Services started successfully.


Exchange Deployment Assistant

We're happy to announce that we've enhanced Exchange Server Deployment Assistant to include support for configuring rich coexistence (also known as “hybrid deployment”) for organizations interested in maintaining some users on-premises with Exchange 2010 and some users hosted in the cloud by Microsoft Office 365 for enterprises. This scenario is in addition to the existing support for configuring rich coexistence between on-premises Exchange 2003 and Exchange 2007 organizations and Office 365.
The new coexistence information for the Exchange 2010 environment is only available in English at this time and requires that your existing Exchange 2010 servers are updated to Exchange Server 2010 Service Pack 1 (SP1).
Rich coexistence (“hybrid deployment”) offers organizations the ability to extend the feature-rich experience and administrative control they have with their existing on-premises Microsoft Exchange organization to the cloud. It provides the seamless look and feel of a single Exchange organization between an on-premises organization and a cloud-based organization. In addition, coexistence can serve as an intermediate step to moving completely to a cloud-based Exchange organization. This approach is different than the simple Exchange migration (aka cutover migration) and staged Exchange migration options currently offered by Office 365 outlined in Email Migration Overview in Exchange Online help.
If you're not already familiar with the Exchange Deployment Assistant, it allows you to create Exchange Server 2010 on-premises configuration and deployment instructions that are customized to your environment. It asks you a small set of simple questions and it provides a checklist with instructions that are designed to deploy or configure Exchange 2010 based on your answers. In addition to the online checklist, you can even print a PDF of your checklist.

Figure 1: The Exchange Server Deployment Assistant (ExDeploy) is a web-based tool that helps you upgrade to Exchange 2010 on-premises, deploy a hybrid on-premises and Exchange Online organization or migrate to Exchange Online

Your feedback is very important for the continued improvement of this tool. We would love your feedback on this new scenario and any other area of the Deployment Assistant. Feel free to either post comments on this blog post, provide feedback in the Office 365 community migration and coexistence forum, or send an email to via the 'Feedback' link located in the header of every page of the Deployment Assistant. Thanks!
