Issues synching with EAS server

[Bugs1012]

Your environment

Windows
TbSync version: (not sure how i see the version but when i check for updates it says no updates found
Thunderbird version: 102.8.0 (64-bit)

Expected behavior

Calendars would synch perfectly.

Actual behavior

When i sync my calendars, i almost always get an error -> "The EAS server did not accept X elements". I go through the event log but can't really understand. The first 5 are "Ignoring RDATE rule (not supported)", and then the orhers are "Bad item Skipped: Object not found (status 8)". When i click help on these issues it takes me to a page about "Forbidden Tasks item in Calendar folder". I don't use tasks on any calendar, so this is confusing.

I have managed to reduce the errors by deleting appointments from my calendar, but it's hit and miss - and not really solving the issue.

Steps to reproduce

...

To help resolving your issue, enable debug logging (TbSync Account Manager -> Help) and send me the debug.log via e-mail (use the title of your issue as subject of the email).

I also have issues with the "Bad item Skipped: Object not found (status 8)" error with tasks, and have found two ways to avoid it:

• First and easiest one: always sync before closing Thunderbird: anything not synced will show the error upon relaunch
• Do not edit tasks if they are not in the current calendar view (ie. your calendar screen shows this week, do not edit last weeks' tasks from the tasks tab)

If the task already shows "Bad item Skipped: Object not found (status 8)", you can almost always fix it by editing the task from the calendar (just clicking edit will work, no need to actually edit anything), saving, and then syncing.

I hope these fixes also work for events,

Getting this error on one calendar for events created in Thunderbird Status 6 is the only thing in the logs I see.
