Suppose you are using mailboxes in Microsoft 365. In that case, you must be aware that Exchange Online Protection uses different ways and techniques to ensure that users will get emails only from authorized and trusted users by maintaining a Safe Sender list.
Even after setting an email as “Safe” or “never as Junk,” the mail continues to go to the “Junk” or “Spam” folder. And the main reason behind this is that the Online Exchange Server hosted by Microsoft is still unsure of the email coming into the Inbox.
Let me say about Whitelist; this is a list of approved sender email addresses. Whitelist email addresses will pass through the spam filters without being blocked.
One can whitelist an email address using two different methods based on their level of security.
Note- Users can add the email address to the allowed sender list in the Anti-Spam policy, as the emails sent from this address will bypass all security checks, including SPF and DMARC.
Mail flow rules are considered a more secure option to keep the DMARC check-in in place.
Users can add the sender to the Whitelist in Office 365 by using the Microsoft 365 Defender.
Now you can see the list is ready with a filter.
Using the above-discussed solutions, one can easily whitelist the email addresses they want. But as we know, there is no guarantee of results from any manual solution. Our important messages still go to the spam folder without our knowledge. Hence whitelisting emails is a way to avoid that situation, but for the safe side, try to back up all your mailbox items. We suggest going for Kernel Office 365 Backup & Restore, a reliable solution to backup all Inbox, Outbox, Junk, Deleted Items, Sent Items, etc., all mailbox folders.
We need to whitelist an email address to have a clean and focused inbox. And to safeguard important mailboxes, give a try to Office 365 Backup & Restore tool; it also backs up all calendar entries like appointments, meetings, events, venue, category, etc. Hope you all find this blog helpful.
