A Microsoft file hosting and synchronization service.
Hi Xavier Riverin,
Thanks for visiting Microsoft Community.
I understand that you are currently experiencing an issue where trying to open a shared document in Word gets stuck at the "Contacting the server for information" progress bar.
Please try testing this issue with a new Windows local account. You can refer to this article on how to create a new local account.
If the problem persists, I suggest testing in a different network environment, such as connecting to a mobile hotspot or enabling/disabling a VPN.
If you have any updates, feel free to share them here.
Best Regards,
