outgoing mail server not working with smtp.office365.com

I cannot send outgoing emails with the microsoft office 365 email server. I configured an IMAP & SMTP Client with Thunderbird, working perfectly. I configured OpenErp with a Google account - works perfectly --> the only emailserver not working seems to be office 365, but as a standalone client using smtp (not native exchange protocol) I guess the issue is not at the Microsoft offering.

Please help, attached my log file error message I get when trying to send an email.

Hi, so I found the solution that worked for me on this site:


Do not forget to add the SPF record in your DNS to mak sure your mail does not end up in the Spam-mailbox.

I would suggest you to recheck the Outgoing email server settings. Make sure the following:

  • Company email address and outgoing email server email address should be same.

  • The alias domain should be blank

  • priority should be less than the SMTP server - localhost, i.e. 10

ok - got a little bit closer. it works with a workaround - but unsure if this is the wanted design?

openerp sends the email under the emailadress which is registered in the user profile who logs into the system. (see /usr/lib/pymodules/python2.7/openerp/addons/base/ir/ir_mail_server.py, line 301:

    email_from = email_from or tools.config.get('email_from')
    assert email_from, "You must either provide a sender address explicitly or configure "\
                       "a global sender address in the server configuration or with the "\
                       "--email-from startup parameter."

how can I now configure multiple users in the outgoing mail server when the SMTP server needs authentication? Is there a workaround? It would be nice having the email-adress and password configuration dialog in the user preferences?

It has been working fine for me for about 4 months. I started having this problem 2 days ago. None of my settings in OpenERP have changed. Something must have changed at outlook.office365.

Okay, so i tried a different provider (godaddy). The error message was similar, but gave some insight: Sender Rejected - MAIL FROM must be a valid domain.\nadmin@xxx.xx.xxxx.xx. Turns out I only needed to change the alias domain from the default (ip address) to my email domain name, on the General Settings. Now smtp through office365 works again. Not sure why it worked before.

No answer as I don't have enough Karma yet.  Just a note to say Ji Lee's method worked for me perfectly. 

Thank you for the steps.

As Eladio Abquina said, it works... Finally. 

In my case, company email and admin email are different.  When I used google admin id with smtp.gmail.com, odoo sends any email whatever the current logged account. However,  google has a limitation to use smtp email, 100 per day. 

Strangly, when I use general smtp outgoing settup which are smtp.office365.com port:587 or 25 email admin id and password, it worked only on the admin account.  I searched and tried all ,but only Eladio Abquina's suggestion is working.

I am going to add on his explanation....I used option3>step-by-step configuration instructions for SMTP relay from the link (https://support.office.com/en-us/article/How-to-set-up-a-multifunction-device-or-application-to-send-email-using-Office-365-69f58e99-c550-4274-ad18-c805d654b4c4)

which are:

1. on office 365 >admin>domain>click primary>Exchange Online>

-copy mx domain address (which is mydomain_com.mail.protection.outlook.com)

-edit the next line  and put your odoo ip address(eg.

                v=spf1 ip4: include:spf.protection.out...

2. back to admin on office 365 >admin>exchange>mail flow>connector>add

from Myorganization's email server to office 365

put the odoo's ip address

3.on odoo

-General set up >  Uncheck "Use external authentication providers(OAuth)"

- outgoing smtp

Smtp server: mx endpoint of domain which copied on step1.

port: 25

security: TSL(STARTTLS)

no username or password. 

4. odoo>developer mode>setting>parameters >remove catchall  and domain

Hope it helps.

As a workaround, I changed the Outgoing settings to just set-up SMTP Relay for Office365

hostname yourdomain-com.mail.protection.outlook.com  

port            25

security      None

Username  <blank>

Password    <blank>

Worked like a charm!

Make sure to set-up your connector as described here:

I did as Manish said, and it works.

Just beware that the blank alias domain: that's on the General settings page.

Setup Office 365 SMTP outlook.office365.com 995 SSL/TLS fails -> Client does not have permissions to send as this sender

1. In Odoo setup a SMTP server using your mail exchange (MX) endpoint record with port 25 no security

2. In Office 365 configure a connector so Odoo can send email to Office 365. Office 365 can then relay email to your organization mailboxes and to external recipients. Office 365 > admin > exchange > mail flow > connectors: configure a connector for your Odoo ("email") server with the internet connecting IP address (CIP: [IP address] from the internetheader the email). In my testcase the IP address of the router connecting to the internet.

So my fix is change code in /opt/odoo/odoo-server/openerp/addons/base/ir/ir_mail_server.py

You need to change "smtp_from" to "smtp_user" and also replace

after this:

If "mail.catchall.alias" is not set it defaults to "postmaster-odoo".



#Because you have "postmaster", but you don't have "postmaster-odoo" on your own provider.

Hope it helps!
