Hi all,

I wrote a small Gambas app to pull my Outlook calendar and mirror it locally. I expected the Microsoft calendar sync to behave once WebDAV / CalDAV was set up, but that’s not what I’m seeing. It imports the events fine the first time, then stops updating completely. This started right after I enabled OAuth on my Microsoft 365 account. Since then I only get 401 errors on the HTTP requests from Gambas. Curl still connects, so the endpoint is alive. I’m no network guru, so I might be missing something obvious. Has anyone here managed a reliable Outlook calendar sync from Gambas?
