M&A expansion signal error acquired company accounts not linked failure

TL;DR

Fix this in the M and A account linking by acting on the exact message first: create parent links for the acquired company accounts using the acquisition announcement domain list, then roll their usage and history into the acquiring customer account. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one record, then rerun the full scope and reconcile the counts.

Use this when

• The operation in the M and A account linking fails with this exact message: M&A expansion signal error acquired company accounts not linked failure.
• The same failure repeats on retry with unchanged inputs.
• A run, import, export or alert is blocked until this item completes.

Not for this skill when

• The message is a permission or platform outage notice. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the M and A account linking, and copy the full message plus the record, account or list involved into the run notes. Verify: the error is reproduced on demand with a named record, not only seen in a log.
2. Apply the specific fix for this error: create parent links for the acquired company accounts using the acquisition announcement domain list, then roll their usage and history into the acquiring customer account. Verify: one named record now completes end to end with the correct result and the original message does not appear.
3. Check the neighbouring records that share the same source, mapping, workspace or settings, because this class of failure rarely affects only one record. Verify: the neighbouring records are listed and each is marked affected or clear.
4. Compare the result counts, fields or alerts against the source in the M and A account linking so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in the M and A account linking on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the record so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Acquired accounts stayed as independent customers in the CRM because no process links accounts after an acquisition closes.

Compatibility: the M and A account linking at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.
