Symptoms
Unable to connect to SharePoint Online using ADFS and manual authentication.
Error Code
Not applicable.
Details
Sharegate only supports connecting to SharePoint Online (Microsoft 365) with ADFS if Windows Integrated Authentication is used.
Solution
1. If you use another authentication scheme, an easy workaround is to create a new account in the cloud that is not provisioned through ADFS, such as [email protected].
2. Try to connect to your site using the "Browser Authentication" mode.
