O365 Migrated Emails going to SPAM in Gmail

[Biju Daniels]

We migrated few pilot users. And when some them sending emails to external, going to SPAM Folders in Gmail. Example I have 2 test mailboxes and if I email from test 1, it goes to gmail inbox and from test 2 it goes to SPAM folder in gmail.  Added an SPF record  include:spf.protection.outlook.com

Still the Same.  Any inputs ?

There can be a variety of reasons for such behavior, and you are not giving us much to work for. Apart from SPF, you might need to configure DKIM/DMARC. And at the very least, you need to check the headers on one of the affected messages. In any case, best thing to do is open a support case and have this investigated.

We have the same issue. Domain is clean, SPF and DMARC are set up. Emails go to gmail spam. They were NOT doing this before switching to O365.
