What does HRESULT 0x80632040 (PEER_E_INVALID_GROUP_PROPERTIES) mean?

PEER_E_INVALID_GROUP_PROPERTIES

Where the peer stack rejects the operation

PEER_E_INVALID_GROUP_PROPERTIES — HRESULT 0x80632040 marks the PEER_GROUP_PROPERTIES structure contains a field combination the grouping layer cannot apply. Treat it as a group membership result rather than a generic peer-networking failure.

Evidence to preserve before retrying

• Record the first failing surface among PeerGroupCreate, PeerGroupGetProperties and PeerGroupSetProperties.
• Preserve structure version/size, group peer name, friendly name, classifier, cloud, scope, flags, authentication scheme and the create/set call.
• Place successful creation or discovery, state-changing events and the failing call on one timeline.
• Keep peer names, identities, record identifiers, invitation data and endpoints in their original Unicode or binary representation.

Controlled isolation

Start from properties returned by a successful group or documented sample, change one field at a time and preserve the exact rejected structure. Change one variable only; simultaneous changes to identity, cloud, database and firewall state destroy attribution.

Neighboring result

PEER_E_INVALID_ROLE_PROPERTY differs because group-properties covers the overall structure; invalid-role-property isolates a role value. Keep both HRESULT values in chronological order because a corrected prerequisite can expose the next validation stage.

Safe response

Correct the offending field or incompatible combination; do not assume every property can be changed after creation. Preserve durable graph databases, group exports, identity certificates and invitation artifacts before changing them.
