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.
Hi,
I'd double check the SPF from Google DNS:
nslookup -q=TXT yourdomain.com 8.8.8.8
SPF should look similar to this:
v=spf1 include:spf.protection.outlook.com -all
If the record SPF is ok, then you should double check how your emails are routed. That is, are they sent directly from Office 365 or are you using some internal mail server to do that.
Finally, you should ask someone to send the email you sent them as an attachment, so that you can access the original mail headers. You can copy-paste headers to Message Analyzer at https://aka.ms/exrca and see how the email has been delivered.
- Nestori, thanks for the response. Yes, we've already done all that. I think we have resolved it by adding a DMARC record in addition to DKIM and SPF.
