Quick Campaign emails blocked by Exchange online server

(0) ShareShare

Posted on by 25

Hi Everyone,

I've run into an issue while sending emails via Quick Campaigns via the Dynamics Marketing app.

I've created a marketing list with contacts wherein another user is the owner. I've enabled rights to be able to send on their behalf. I used an existing template and sent the message via quick campaign to a marketing list containing about 400 recipients. 

The email arrived in the inbox of some users, but ended up in spam. The rest of the users are shown as "success on the Quick Campaign page. The owner of the Contacts has received nearly 250 undeliverable emails in his inbox saying Outlook doesn't recognise them as a valid sender. The user was blocked from sending emails which I had to unblock from Exchange admin center. 

I was successful in sending a similar quick campaign with another user who had the same security role. The only difference was that it had about 350 contacts.

I'm afraid using this method for bulk mails risks our company domain. I am aware that Dynamics Marketing should be used for sending bulk mail. But we want to use quick campaigns as an alternative to distribution list to track email responses and also send seemingly personalised email. 

Can anyone advise if the Exchange online settings are to blame or something to do with dynamics and the user?

Would be happy to share any other info if required.

    Hi,

    Firstly, please check the validation of the mailbox in Dynamics.

    1. Sign into Dynamics 365 (online) as a user with the following privileges:

    • Global Administrator or Exchange Administrator role in Office 365

    • System Administrator role in Dynamics 365

    2. Navigate to Settings and then click Email Configuration.

    3. Click Mailboxes.

    4. Change the view from my My Active Mailboxes to Active Mailboxes.

    5. Select the mailbox and then click the Approve Email button.

    6. After the mailbox is approved, you can select the mailbox and then click the Test & Enable Mailboxes button.

    NOTE: If the test results are something other than success, you can open the mailbox record and click the Alerts section. View the details of any errors that were logged.

     

    If it is approved successfully and the issue still exists, please try to follow the steps in this issue:

    Not recognized as a valid sender. The most common reason for this is - Microsoft Community

    Hi Nya,

    Thank you for your response.

    A few things to mention here. I can see that the affected user's email already has a success in the mailbox configuration. Would it make any difference if I re-approved and tested it?

    I followed the steps in the link to unblock the account. But the link does not specify why it is labelled as spam anyway.

    From what I understand, Dynamics send emails from Outlook. The quick campaigns that I'm using would ideally follow Outlook sending capacities. In the past we have sent similar emails from Outlook directly by pasting a long (400-450 long) recipient list and had to trouble sending to up to 1000 members an hour. This was long before modifying outgoing capacity of Outlook.

    But suddenly this blocking occurred and now the affected user (after unblocking his account) is also unable to send bulk email the traditional way. I spoke to Dynamics support and they simply handed it off saying its not something we can troubleshoot so speak to O365. And with O365 (which was already difficult to get a hold of), I get generic replies and get sent links to documentation about email capacities that don't seem to apply in real life.

    They weren't able to determine why exactly the system picked it up as spam and proceeded to block the sender.

    Bit of a rant. But its business critical which is why its frustrating when someone's email just gets blocked for no reason.
