Microsoft Graph: AIInteractionHistory api and OData filters

Hi,

I'm calling the AIInteractionHistory api here and receiving data but would like to restrict the returned data for performance.

The documentation provides one example on how to do this:

GET https://graph.microsoft.com/v1.0/copilot/users/{id}/interactionHistory/getAllEnterpriseInteractions?$filter=appClass eq 'IPM.SkypeTeams.Message.Copilot.BizChat'

This works as expected.

However trying to apply a filter based on the createdDateTime

GET https://graph.microsoft.com/v1.0/copilot/users/{id}/interactionHistory/getAllEnterpriseInteractions??$filter=createdDateTime gt 2026-01-01

fails returning:

{
  "error": {
    "code": "InternalServerError",
    "message": "Failed to execute request.",
    "innerError": {
      "date": "2026-02-19T09:30:20",
      "request-id": "a840d14c-5428-471d-aac1-5a654dd9d745",
      "client-request-id": "a840d14c-5428-471d-aac1-5a654dd9d745"
    }
  }
}

It also looks like other properties cannot be used in the filter such as sessionId, requestId etc.

GET https://graph.microsoft.com/v1.0/copilot/users/{userId}/interactionHistory/getAllEnterpriseInteractions?$filter=sessionId eq '{sessionId}'

returns:

{
  "error": {
    "code": "BadRequest",
    "message": "The entity property 'sessionId' and operationKind 'Equal' is not allowed in $filter query.",
    "innerError": {
      "date": "2026-02-19T09:46:54",
      "request-id": "a32843a6-9551-4721-a046-77342e009a74",
      "client-request-id": "a32843a6-9551-4721-a046-77342e009a74"
    }
  }
}

So my questions are:

• As it appears that createdDateTime in the filter is supported, is this a bug or is the filter syntax incorrect?
• What other properties are supported in the filter (sessionId/requestId would be really useful for us) with examples?

Hope you can help, thank you.
