Problem:
During a SharePoint, Teams, or Office 365 migration, you are facing the error: Connection to the site /sites/… failed. Please verify your credentials and make sure you have access to this site.
Resolution:
As mentioned in the error message, the migration engine is not able to connect to the site for either one of these reasons:
- The credentials you provided in your connector are incorrect. Please correct them.
- You don’t have the right to access this site. To verify if you have access, please log in to Office365 and try to access the site URL (yourtenantname.sharepoint.com/site/sitename). If you don’t have access to the site, please give the migration account the needed rights.
