## TL;DR
Check recipientTypeDetails, not just the mailbox type label. Converted mailboxes keep stale labels in some views while the underlying type changed.

## Error
```text
(audit treats 30 converted mailboxes as shared; they consume user licenses; no error text)
```

## Steps
1. Confirm the conversions: list mailboxes the audit calls shared and check their recipientTypeDetails. Expected: the converted ones identified.
2. Fix the agent's classification to key on recipientTypeDetails (SharedMailbox vs UserMailbox) from the live directory. Expected: classification matches reality.
3. Re-run the reconciliation. Expected: converted mailboxes counted as user mailboxes with their licenses.
4. Decide per mailbox: convert back, license properly, or remove. Expected: no unlicensed user mailboxes.

## When to use
- Converted mailboxes are misclassified in the audit
- License counts do not add up around shared mailboxes
- Conversions happened recently

## When not to use
- The mailboxes were never converted (a different classification bug)
- The issue is a proxy-address conflict (a different problem)
- You want them shared (convert them back)

## Tool compatibility
Microsoft Exchange Online and Entra directory data.

### Variant phrasings
### conversion done in the admin center but the API still says shared
Wait for directory sync, then re-check; the API lags the UI.

### audit uses a cached mailbox list
Refresh the cache; conversions are invisible to stale data.

## Why it happens
Mailbox conversion changes the underlying recipient type, but labels and caches lag. Audits that read the label instead of the type inherit the staleness.
