Whitelist Domain in Office365
Having trouble with our automated emails getting blocked or delayed? Adding
file.acto the allowed domains list will enable them to bypass the spam filter. Here's how:
Click on Policies & rules in the menu
Choose Threat policies in the list
Select Anti-spam inbound policy (Default).
Scroll down and click on Edit allowed and blocked senders and domains.
Click on Allow domains.
Fill in the domain that you want to allow
Click Add domains
Click on Save.
You have now added
file.acto the Office 365 spam filter allow list. From now on, all the emails with that domain will not be marked as SPAM.
