google marking office 365 emails as spam

New Contributor

We have an Office 365 business subscription for our business and use Outlook 365 client to send emails. While all our emails a non Google email centrepiece, email recipients using Google email service providers particularly are complaining our emails land in their spam folder. I have tested this with 15 odd GSuite email accounts to whom I never emailed before. 

 

Any help?

There can be a number of reasons for that, at the very least check the email headers as they will often reveal additional information as to why a given message might have been marked as spam. For example, SPF or DKIM/DMARC failure, blacklisted IP, etc.

Assuming all of these setting to be correct with DSRC.com, what else could be the problem?

Domain is not blacklisted.

@DanManoharan as Vasil already mentioned, analyzing the email header would be the best way to identify why emails got marked as junk. Also Google can help if you open a support request and I'm sure they have a good explanation for it.
