MessageOps Config365 is small application which simply creates a new Outlook profile connected to an Office 365 mailbox.

When the Configure Button is clicked a new Outlook profile will be created which is connected to the user’s Office 365 mailbox.
If you are migrating from Exchange 2003 or already have the Autodiscover records pointing to Office 365, you should be able to run the application with the default settings (Prefer Local XML unchecked).
If you are migrating from Exchange 2007/2010, then you likely have the Autodiscover records created and pointing to your local Exchange environment. In this scenario it is necessary to select the Prefer Local XML option to disable the normal Autodiscover process. If you do not check the Prefer Local XML option, a new profile will be created, and it will be connected to the Office 365, but after a reboot, Outlook will likely attempt to connect back to the local Exchange Server.
When the Prefer Local XML option is selected the following registry keys are set to the values below.
Config 365 is a free application which can be accessed at config365.com . It’s available as a ClickOnce application or a standalone .exe file.
