I have a very similar problem trying to transfer my email accounts from My Samsung Tablet to My PC
I copied my gmail, and BT account details into Windows mail in MS win11 Pro
the BT account installed perfectly, but my gmail account comes up with the windows mail; message
"We couldn't Access this account.
You might need to update your password, or give the account permission to sync to this device" .
I have tried to give the permission without success, But it I log on line direct to my Google gmail account
using the same password and details, I get access to all my email messages.
Where am I going wrong ?
