The user name or password is incorrect. (Exception from HRESULT: 0x8007052E) + Migration to modern folders

Hello everyone,

I’m currently working on modern folders migration and i try to start a process from the executor and i have this error message.

“The user name or password is incorrect. (Exception from HRESULT: 0x8007052E)”

I tried to change the password of the user in the old classic folder here :

I still got the error message. Can you indicate me where i must change the password please ?
I tried on this page (tenant → robots), but i can’t see an option to update a password. Is this a rights restriction ?

Thank you !
