Migrated to O365. Emails going to GMAIL Spam.
You can try checking the headers of one such email which ended up in the spam. Maybe you will find some indication (a header added by Google) why it was marked as spam. You can also try opening a support ticket with MS, but i suspect they will tell you that everything is fine on their end and will suggest to contact Google (which is tough to do). I have found such form to fill https://support.google.com/mail/contact/msgdelivery Maybe it will work.
Just guessing. But a few weeks ago we were getting a lot of phishing emails from bogus addresses, but emails were actually sent from MS servers (someone hacked outlook.com/office 365 mailboxes). If a lot of spam is sent through such Exchange Online server, then i think it can be blacklisted. Though in such case emails probably shouldn't even reach mailboxes.
I think we have it figured out. Adding a DMARC in addition to DKIM and SPF may have solved it. Either that or now enough time has passed since Google received a massive amount of spam from O365 as in your message... Thanks.
We are also facing same issue
SPF , DKIM, DMARC record cofigured still my email going to spam only to gmail users.
any one more suggestion?
Hi Arun,
I've seen a lot of instances and complaints like you have mentioned.
Business emails landing in Spam.
There are few things to be done in order to solve the above given problem:
- Include all the domains and IP's which are allowed to send emails on behalf of your main policy domain in your SPF record.
- Ensure the DKIM keys are getting signed and verified properly for the main policy domain.
- Make sure that the domains associated and used in the Email headers, pre-headers, email body content, URL used in email are NOT blacklisted at any DNSBL or RBL's worldwide like Spamhaus, SpamCop, Baracuda, Talos, etc.
- Make sure the sending IP's are NOT blacklisted at any of the DNS RBL's worldwide.
- And finally ensure that the DMARC policy is set correctly. If you are 100% sure about monitoring then you must go ahead to quarantine and reject policies ASAP. Quarantine and Reject policies are double edged sword. If you don't know what you are doing then you are going to hamper the email deliverability even worse than earlier.
Hope that helps.
Thanks.

- They won’t give an answer. They direct us to the public google page. This has been going on for months. The domain is clean, server is clean... not sure what to do about it. Will probably have to switch from O365 at this point. We have lots of clients but it is only affecting a few of them.
