Without it reading the actual value of a channel is hard. Patching the property can be done with some workarounds using additionalData (see below).\n\nThe object:\n\u003cimg width=\"691\" height=\"606\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/aa459053-2cb0-4a74-934a-5a8840bffadb\" />\n\nA graph request:\nhttps://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}\n\u003cimg width=\"324\" height=\"405\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/4e829480-d34f-4a59-af41-6e67fdc88826\" />\n\n### Expected behavior\n\nThe property should be present in the `graph.models.Channel`-Object. Also an enum for the two allowed values would be nice.\n\n### How to reproduce\n\nSimply use some sdk version and try to read or patch the `layoutType` of a channel.\n\n### SDK Version\n\n6.63\n\n### Latest version known to work for scenario above?\n\nnone I guess\n\n### Known Workarounds\n\nFor a patch you can use one of:\n```\n.getAdditionalData().put(\"layoutType\", \"post\");\n.getAdditionalData().put(\"layoutType\", \"chat\");\n```\nI don't know if there is a workaround for reading.\n\n### Debug output\n\n_No response_\n\n### Configuration\n\nThis should not impact the issue, since it is not present in the models of the java-SDK.\n\n### Other information\n\n_No response_","author":{"url":"https://github.com/coinzz","@type":"Person","name":"coinzz"},"datePublished":"2026-05-06T13:42:46Z","url":"https://github.com/microsoftgraph/msgraph-sdk-java/issues/2586"}
