SYMPTOMS
When you upgrade from Microsoft Exchange Server version 4.0 to Exchange Server 5.5, Setup may terminate with the following error message:

An unexpected error has returned, the error is 0xc1060107



CAUSE
This problem occurs because Setup mishandles a return code while upgrading the private information store.



WORKAROUND
To work around this problem, upgrade to Exchange Server 5.0, and then upgrade to Exchange Server 5.5.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5.

A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next service pack that contains this fix. Contact Microsoft Technical Support for more information.



MORE INFORMATION
During the upgrade process, the Setup program must upgrade the public and private information stores to a version that is compatible with Exchange Server 5.0. It is during this process that the upgrade fails.

In order to use the fix, you must copy the Server\Setup\ folder from the Exchange Server 5.5 CD-ROM to a local hard drive, copy the fix to that folder, and then run Setup from there.
