QcalAgent stopped syncing Outlook Calendar. After reconnecting the Microsoft account, it does not bring results on several qnap devices, the same effect. The question is whether Microsoft has not introduced additional security and is now cutting off the application.
Hello There,
Regards,
Our technical team identified the issue and its related to Microsoft Graph APIs. Microsoft is planning to add a patch to fix this issue.

**Describe the bug**
The call list all calendars (/v1.0/me/calendars) returns a … 500 Internal Server Error.
This call seems to no longer work for a lot of users, we get error reports from a lot of users.
I tried with 4 accounts:
personal live account -> error 500
personal outlook account -> error 403
personal hotmail account -> error 403
O365 account -> OK
This call no longer seems to work properly for personal outlook/live/hotmail accounts. Probably started in the last 24hours.
**To Reproduce**
Steps to reproduce the behavior:
1. Go to Microsoft Graph Explorer: https://developer.microsoft.com/en-us/graph/graph-explorer
2. Create a token for a personal outlook/hotmail/live account (not O365, that seems to work), consent to e.g. Calendar.Read scope
3. Go to "Outlook Calendar", list all calendars.
4. Click on "Run query".
5. See error, either 500 or 403 while haven given consent.
**Expected behavior**
No errors
**Screenshots**
500 for my account:
403 for another account while consenting
We are monitoring this and once Microsoft updates the system we shall again try to test and announce here that the problem is resolved by Microsoft.
