Error Message
Cannot create document: Path too long (maximum 400).
Cause
This error occurs when there are too many characters in a file path name in OneDrive for Business. OneDrive for Business now supports file path names with up to 400 characters.
Resolution
Use the IncreasePathLengthLimit=1
Advanced Support Option to circumvent this error. Add IncreasePathLengthLimit=1
to your project to allow MigrationWiz to take advantage of the 400-character limit.
