Issues trying to delete chat messages in Teams in Graph

Question

I am attempting to search and delete a message in Microsoft Teams, I have found a procedure document from Microsoft that shows how to do it via the Purview Portal and Graph Explorer here, a cumbersome process to say the least, I get to the step where it has you run the POST request using this, while replacing my values with the correct id's.

https://graph.microsoft.com/v1.0/security/cases/ediscoveryCases/{ediscoveryCaseID}/searches/{ediscoverySearchID}/purgeData

When I Run Query I am presented with an error that states: "PurgeType and PurgeArea parameters must be specified.", now here is where I am confused, when referencing the sourceCollection: purgeData documentation

it specifically states::

Request body

Don't supply a request body for this method.Request body Don't supply a request body for this method.

Only when I provide the following arguments in the Request Body do I get a Acccepted Query:

{

  "purgeType": "recoverable",

  "purgeAreas": "teamsMessages"

}

The issue is the message is still there, it has been about 48 hours and I am not seeing any retention policies enabled, apart from the ones I have disabled. I am seeing a few threads on here but with no definite answer.

Has anyone done this before and is able to point me in the right direction?

Answer 1

Hi @Stanley Nichols- When you make the POST request, the body should look like this:

{

Note that purgeAreas should be an array.

Answer 2

@Sayali-MSFT

So when I provide the following:

{

"purgeType": "recoverable",

"purgeAreas": ["teamsMessages"]

}

Parameter PurgeAreas does not accept collection values.

Answer 3

Thanks for posting this question, you should be able to post this action by adding the the Request body:

{

"purgeType": "recoverable",

"purgeAreas": "teamsMessages"

}
