Differences in Hold Locations in Microsoft Compliance Center: Premium vs. New Experience

Hi @Courtney (O'LOUGHLIN), Amy ,

No, you don't need to rebuild the holds on every case. Holds are stored in the service, not in either interface. The new experience reads the same data, and the old one was retired on August 31, 2025. Premium tracks custodian and other data source locations through system default policies. The new screen may show them somewhere else (like the Data sources tab), so they can look missing when they aren't.

Check if a hold is really missing by the following steps,

1. Open the hold report in Purview (you need eDiscovery Administrator or Manager permissions). It lists every hold and its locations, so you can compare it with what the case shows.
2. In Security & Compliance PowerShell, run Get-CaseHoldPolicy -Case "<case name>" and Get-CaseHoldRule to see the real locations.
3. Test a few cases first. If the hold report lists the locations, nothing is wrong.

If locations are missing do the following,

• Check the "Location error" column in the hold report first, since a failed hold can cause this.
• Re-add the locations only on the affected cases.
• If many cases are affected, contact Microsoft support.

Please let me know how it goes, if it worked please accept the answer so the others can get the answer if they have the same issue.
