I used to save my contacts on my Outlook 2019 (16.0.13530.20418) 64-bit and having them synced in my Android phone with Outlook app installed.
Now it's no more so, and I have no idea how to troubleshoot. I just reset the account on my mobile but the contacts is still not present.
The sync is immediate between Outlook 2019 and the internet (i can see the modifications on outlook.live.com), but then they stop before reaching my phone.
Despite the facts that mail and calendar are OK
