Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Bastien G,
Good day.
Thank you for reaching out to Microsoft community.
According to the description, looks like your concern environment is also connected Exchange on-premise server or Windows server or VDI machine for Outlook application, , I have consulted with my team, I would like to share some more specific information with you. Actually, Microsoft has separate channel resources where our related most valuable professional and community members can provide possible information for certain different support scope and attributes, so would you mind to contact and place your concern on our dedicated Microsoft Q&A forum channel resources?
Actually this forum does not focus Windows server or VDI machine or Exchange on-premise server for Outlook application related situation, but this forum is mainly focusing and handling Office 365 exchange online service related concern. But there is another dedicated expert and specific community for your mentioned concern.
I would really appreciate your precious time. Thank you again for your kind cooperation.
Sincerely
Vaidya Darpan
