Error Message
"Unable to access Team xxx SharePoint site. Check the team name length. This cannot be longer than 247 single byte characters. If the team was recently created, retry migration after a minimum wait of 5 minutes."
Cause
This is due to a SharePoint name character length constraint in the Microsoft system.
Resolution
Verify that the SharePoint site is functioning properly on the Source, then either retry or skip using the Advanced Option SkipUnprovisionedTeamSites=1 to skip these sites at the Source.
Notes:
- This option is added to the Support Options in the Advanced Options page.
- This Advanced Option does not work for the Destination.
