Why is Splunk Add-on for Microsoft Security for GCC not working?
Hello all,
It would seem a swift migration to Splunk Add-on for Microsoft Security is highly recommended:
"Customers currently utilizing Microsoft 365 Defender Add-on for Splunk are strongly recommended to migrate to this new Splunk supported add-on after reading the migration section of the documentation."
I haven't been able to get this app to work with GCC, has anyone else? Anyone know when that support is coming?

Are you having issues with getting the data in? Can you dig into index=_internal to find errors in the TA logs?

We are getting error 400 "Resource not found for the segment" on the calls the Add-On is making. I confirmed the credentials are good, we are getting successful logins.

I believe when I posted this support had not yet been added. At this time, this app does support GCC and I have gotten it working in at least one environment. My guess would be you are running into an Azure permissions issue.

You got it working in GCC or GCC high? We are not able to get it working for GCC high.

Sorry, only GCC (literally the "GCC" selection an the API input configuration). I have not had the opportunity to work with GCC high yet so I cannot confirm if it works.

@m_pham can you validate that this can work/is supported for GCC high? I notice that in the Splunk addon for Microsoft Offie 365 that I can pull my data from GCC high in, but it would be amazing to know that we could visualize that data with the Microsoft 365 App for Splunk. So far it looks like the APIs do not support that data.

I don't have experience with this TA but it may be a permissions issue, so I'd recommend taking a look at that on that:

Bump. I am running into the same issue. Can we please get GCC high support for this app?
