losing calendar on machine restart about tbsync

[alistair-low]

I've also seen this issue a few times over the last few months. My calendar and contacts disappear, and I have to reselect them in TBSync. I'm running Windows 11 and TB 115.9.0

This also started happening to me on a weekly basis. All my checked sync items in TBsync suddenly go unchecked. I have to re-check them and sync again. About 1 week later, boom, happens again. I am wondering if it is because authorization is being lost somewhere upstream? This problem might coincide with my also having to re-authenticate my Office365 calendar more often? I have not been able to directly correlate these events. I'm running Windows 10, TB 115.9.0 (32-bit), TBSync 4.8, and Provider for EAS 4.8.

I'm seeing this on roughly the same frequency as @mewalter as well as having to re-authenticate my Microsoft account

For me, it happens sometimes at random when it has been running in the background for days or weeks. Last time, I got this in the log:

It's also a bit of work when reenabling them, as it marks other people's calendars as writeable, visible and notifications enabled by default.
