Issue with Outlook Calendar Integration on Cal.com Self-Hosted Instance

[dennisverberk1234]

Hello all,

We are currently experiencing an issue with our Cal.com self-hosted instance. Specifically, we are unable to connect Outlook calendars.
We have already reviewed and confirmed all security settings for Outlook calendar integration with third-party apps, and everything appears to be configured correctly. Integration works fine with other applications, this issue seems to be limited to Cal.com.

Please see the attached video for reference. Could anyone advise what might be causing this problem?

Looking forward to hear it! Thanks in advance
