Error initializing session for virtual machine %1. The error number is %2. Make sure Microsoft Exchange Store is running. Also, make sure that there is a valid public folder database on the Exchange server.

This Error event indicates that the Microsoft® Exchange Server that logged this event could not initialize a MAPI session to a public folder store. A MAPI session to the public folder store must be initialized for Exchange Server Schedule+ Free Busy functionality to work correctly for Microsoft Office Outlook® 2003 or earlier clients.

To resolve this error, follow these steps:

1. Make sure that at least one public folder store in your Exchange organization is in the Mounted state.

2. Review other related Error and Warning events in the Application and System log. These related events may help you find the root cause of this event.

• If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
