Difficulty in activation my Outlook classic (2013)

Hi,

Earlier this year I bought Office 2024 family . That purchase appears in my account details. I installed Outlook classic on my old PC with the bought licence. Everything was perfect.

I have just switched from my really old PC (running Win 10) to a new PC.  On my new PC, I managed to install Outlook classic. Inside my new Outlook classic  I use my usual account pie****_****@videotron.ca. 

Everything works well but it warns me that it cannot activate Office with my Microsoft pna*****@outlook.com account and suggests I use another account.

When I click on 'Try Another Account', it does nothing but re-displays the same error message. It loops indefinitely

I looked up the accounts and actually it showed my two addresses, the @outlook.com and the @videotron.ca. I deleted the @outlook.com address using Account parameters, thinking this may help as there would be no ambiguity.

It also tells me I have to correct this by 9/20.....

The new PC runs Win 11 Family, Version 23h2

Installed software:

• Microsoft 365 Copilot
• Microsoft Outlook 2016 fr-ca
• Microsoft Office Family fr-fr

I am new to this and find it quite confusing

THANKS IN ADVANCE FOR ANY HELP !

Pierre
