Hi @Anthony Jacques ,
Welcome to our forum!
Please kindly understand that only English is support in the forum and it's suggested that you could post your issue in English for our better research. According to the machine translation, i understand that some users have been stuck when opening Outlook on their RDP sessions, right?
If so, it's suggested that you could try to use the Microsoft Support and Recovery Assistant, which works by running tests to figure out what's wrong and offers the best solution for the identified problem.
-Supprimer le profil est recréer le profil avec un nom différent
Do you mean that you have tried to create a new Outlook profile? If not, it is suggested that you could try to create a new profile(Control Panel>Mail>Show Profiles>add) and add the account for testing to check if there are some differences.
In addition, in order to further confirm if the issue is related to the RDP, it's suggested that you could add the same account outside RDP to check if the issuer persists.
