Testing Purview retention policies

[FishyWishy]

Hello,

I'm looking for a method to report on if a retention policy is actually applying - for example, we have a policy that deletes emails older than 10 years. Is there something that I can show to prove it is working?

I've looked briefly in the audit logs, but that can be tricky to navigate.

Dear @FishyWishy,
From my opinions, you can identify and check your policy first for errors https://learn.microsoft.com/en-us/microsoft-365/troubleshoot/retention/identify-errors-in-retention-...
Then you can test a sample account/location with shorter retention period.
Hope to receive more ideas from everyone.

Thanks,
Hieu Le

I've found this issue difficult in the past, but have found using UAT to test on a small batch of users to help with this. 

Also, the following link may or may not be of use:
