    I have a problem when I use an Office365 account in order to send newsletters.
    I filled the fields in the plugin setup page (smtp.office365.com, 587, TLS, username, password) and when I try to test it i get an error:

    “SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 0.35250:D1180000, 1.36674:0A000000, 1.61250:00000000, 1.45378:02000000, 1.44866:D1230000, 1.36674:0E000000, 1.61250:00000000, 1.45378:D6230000, 1.44866:02020000, 16.55847:F4110000, 17.43559:0000000024020000000000000000000000000000, 20.52176:140F908C1F00103100000000, 20.50032:140F908C8F17000000000000, 0.35180:140F908C, 255.23226:9F19 SMTP code: 554 Additional SMTP info: 5.2.0”

    Do i have to make any changes in my email account settings?



    I had the same problem. I fixed it by allowing this on the exchange server, cuz this is the effect i wanted.
    This happens you’ve probably set a diffrent email address and senders-name in the general settings of thenewsletterplugin, then it is in the smtp and the exchange server.
    You can either set everything the same address and name, or enable this on the exchange via powershell with this command: (without the quotationmarks)
    ‘Set-OrganizationConfig -SendFromAliasEnabled $true’


    Fix issues with SMTP client submission
    I set up my printer for SMTP client submission, but it still can’t send emails
    1. If your printer didn’t require a password for the email address you entered, your printer is trying to send emails without logging on to Microsoft 365 or Office 365. SMTP client submission requires your printer to log on to Microsoft 365 or Office 365. Direct send and Microsoft 365 or Office 365 SMTP relay do not require a logon; consider one of these options instead.
    2. Your printer or application must send email from the same address that you entered logon credentials for during email setup. If the printer or application tries to send email from a different account, this results in an error similar to:
    5.7.60 SMTP; Client does not have permissions to send as this sender.
    3. Test the user name and password by logging on to Outlook on the web, and try to send a test email to make sure the account is not blocked.
    4. Next, test that you can connect to Microsoft 365 or Office 365 from your network by doing the following:
    Follow the instructions to install the Telnet Client tool on a computer on the same network as the device or application.
    Run the tool from the command line by typing telnet.
    Type open smtp.office365.com 587 (or substitute 25 for 587 if you are using that port setting instead).
    If you connected successfully to an Office 365 server, expect to receive a response line similar to this:
    220 BY1PR10CA0041.outlook.office365.com Microsoft ESMTP MAIL Service ready at Mon, 1 Jun 2015 12:00:00 +0000
    If you can’t connect to Microsoft 365 or Office 365, your network firewall or Internet Service Provider (ISP) might have blocked port 587 or 25. Correct this so you can send email from your printer.

    5. If none of these issues applies to your device, it might not meet requirements for Transport Layer Security (TLS) encryption. Your device must support TLS version 1.2 or above. Update the firmware on the device to solve this, or try one of the other configuration options where TLS is optional.

    Hope this gives you a brief outlook.
