Utilisation d’Outlook classique sur Windows pour la messagerie personnelle, le calendrier et la gestion des contacts
Thanks for sharing the details, Roger!
Your outlook could be stuck on one of the October updates. Some October updates caused connection errors for Outlook 2016/2019 and Microsoft 365.
If you’re not on the latest build, go to File → Office Account → Update Options → Update Now.
See if this helps. If you need further assistance just let me know.
Best regards,
Kimberly
