Gmail Sent Through Outlook Client Goes to Spam
My client has a Google Workspaces domain. Some of their users send mail via Gmail online. Others use the Outlook application (NOT OUTLOOK.COM).
Recently, any messages sent from the Outlook Application go to the recipient's spam/junk folder.
We are using the gmail smtp settings in Outlook. It is the latest version of Outlook 365. This happens whether this is Outlook for PC or for Mac.
IMPORTANT: If we send the same message from gmail (mail.google.com) instead of from the Outlook application/client, the message is NOT marked spam.
This seems to be something that Outlook adds to the headers of the message. To date, we've unable to find a fix. Getting rid of Outlook for some users isn't really an option.
Any assistance would be greatly appreciated.

- Evenin Feb 2022 this problem persists. Anybody have any fixes yet?
It seems I resolved the problem configuring the DKIM & SPF records into DNS server's domain provider.
Google webmail uses a different SMTP server than smtp.gmail.com

- Hi mate, can you please share what exactly you did?
I have the same issue with 2 different customers.
All of them:
- use smtp.gmail.com:587/TLS (I tried 465/SSL) too;
- mail sent by the client outlook 2019 (no outlook 365) are marked as SPAM from many incoming servers;
- mail sent by Gmail's webmail are successfully sent
- SPF & DKIM records inserted into DNS server
Are there somebody that have found a solution?
Thanks

- Have any of these solutions worked for anyone? I think the issue has something to do with a Gmail issue and their new security update, rather than something that can be fixed via a setting change in Outlook. But I can't find any articles from Google regarding the issue.
MatthewMoran Hi Matthew
Did you find a solution for your problem as one of my clients is having exactly the same issue.
They are estate agents and need to use the Outlook software in conjunction with their managemnt software
When they send to any microsoft email address, eg outlook.com live or hotmail via Outlook it goes to the customers spam, but when they send via gmail web it goes tot he clients inbox
markmcbride1000 My friend has started running into this. It appears to happen when he uses Outlook AND when he is on his home internet connection (FiOS). It does not happen when he is on another network or if he used the GMail web interface. I see that when he uses Outlook his IP address is included in a header. He requested and got a new FiOS ip address but that did not help unfortunately.
Hi mpvosseller
I and some friends have same issue.
Cant send from a microsoft, ie outlook or hotmail etc as it goes to their spam.
Even when they accept as not spam, still happens.
I can reply to there email and it goes to their inbox.
some contacts in gmail this is there only contact, so I cant tell them to look in the spam box.
How do I fix this?
Hello MatthewMoran,
I'll try to reproduce the issue. When you say "Outlook application" you mean Outlook for Windows? If so, what's exact version?
Also what happens if your client will run native Windows e-mail client instead of Outlook?- https://docs.microsoft.com/pl-pl/microsoft-365/security/office-365-security/outbound-spam-controls?view=o365-worldwide

I hope it will be helpful - please write if it worked?
