ERROR_DS_HIERARCHY_TABLE_TOO_DEEP
The address books are nested too deeply. Failed to build the hierarchy table.
ERROR_DS_HIERARCHY_TABLE_TOO_DEEP is Windows status 8628 (0x000021B4) associated with construction of an address-book hierarchy with excessive nesting.
Likely impact: Address-book generation and clients depending on that hierarchy remain incomplete until the structure is simplified.
Typical causes
- organizational containers are nested excessively.
- a cycle-like migration layout expands the hierarchy.
- automated provisioning creates one level per tenant or group.
- legacy address-list design exceeds current limits.
Troubleshooting steps
- Verify that the address-book container graph fits within the supported hierarchy depth.
- Collect hierarchy path and depth and container parent relationships.
Useful evidence
- Collect recent provisioning changes.
- Collect the first object at which construction fails.
Recovery and retry
Flatten or partition the address-book hierarchy through a planned migration and rebuild the table after replication.
Related errors
ERROR_DS_BUILD_HIERARCHY_TABLE_FAILED is a general build failure; this code identifies excessive nesting as the cause
Example
A tenant provisioning job creates hundreds of nested address lists. Moving them under a flatter set of regional roots lets hierarchy generation complete.
