Purview DLP Blocks Sharing Files with Specific Domains or Users
Hello TonyRedmond​ I have created a DLP policy to block gmail.com for SSN but what I am seeing that other domains is also blocking whereas that is not mentioned in the block list, Is it expected?
I also see, external users are getting access denied but got the option on page to request access from Site Owner and owner can get the option to allow or deny request.
Is this expected ?

Two things. First, the DLP rule blocking other domains? That usually means your policy is scoped too broadly. Check if you have "any domain" selected as a condition elsewhere. Second, the request access option is expected behaviour. DLP blocks sharing, but site owners can still approve requests manually. That is by design. Double check your policy scope and test with a single domain first.
