Hello everyone,

I have a client who is experiencing an error response when performing Admin Phishing Submissions of the Quarantined emails.

All previous submissions were okay. No changes performed recently on Exchange Online.

Suddenly, when trying to submit a Phish email to Microsoft, we are faced with the following:

We did not receive the submission, please fix the problem and resubmit.
It could be due to a policy or rule that blocks messages from getting to our service. The list of addresses that need to be reached is located here.

The links is irrelevant and doesn't contain any addresses.

I would appreciate any input or details on how to approach this.

Thank you!
