Hello Tiago,
MS proposes the following steps (don’t know if you already tried it)
Press the Windows key + R to open the Run Window. In the Run Window enter the following: %localappdata%\Microsoft\OneDrive\onedrive.exe /reset Click OK. The OneDrive system tray icon on the desktop should disappear and re-appear after a minute or two. If the OneDrive system tray icon does not re-appear after a few minutes, do the following.In the Run Window Enter: %localappdata%\Microsoft\OneDrive\onedrive.exe
Cheers
Claudia
