Hi @GV IT,

At a personal level, which sounds like what is happening here you can add the email to the safe senders list

https://support.office.com/en-us/article/block-or-allow-junk-email-settings-48c9f6f7-2309-4f95-9a4d-...

They may also have an inbox rule that is causing it.

At an organisational level if it happens to multiple users you can also whitelist the email/domain on the allow list

In terms of recovery try deleted items folder in the mailbox first and if not there try recover deleted items in OWA

https://docs.microsoft.com/en-us/office365/enterprise/recover-deleted-items-in-a-mailbox

If you have a journaling solution such as Global Relay you may be able to restore back from that

Hope that answers your questions

Best, Chris

You seem to have a policy that specifically chooses to delete spam messages, so you might want to take a look at the policy settings and update them as necessary.
