A form doesn't appear in the target environment after importing an unmanaged solution

Applies to:   Power Platform, Solutions

Symptoms

After you import an unmanaged solution, a form included in the solution doesn't appear in the target environment.

Cause

During the export of unmanaged solutions, some forms that haven't been modified are exported with the attribute unmodified=1 in the FormXml node of the customizations.xml file located in the solution package. This attribute ensures that the form will be omitted from the import when the same solution is imported into a new environment, even though these forms are part of the solution being exported.

Workaround

To avoid this issue, the form must have active customizations to be exported without the unmodified=1 attribute. To verify this, extract the exported solution package, search for the FormXml node in question within the customizations.xml file, and check if the unmodified attribute is present.
