Hi,
I have got a problem with sending invoices via ERP system from 3 august 2021. When invoices are sending "Office 365 Defener" is blocking account using to send mails with invoices. I can unlock this account in "restricted users", but situation repeats about 3 days.
I tried add rule in threat policy. The result was account was not seen in "restricted users" but it was blocked either. I have no idea where I can aprove this account for sending mails via ERP system.
I will be grateful for your help.
