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.
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.
