When uploading new campaigns to Microsoft Advertising via the platform, the upload could fail and you may encounter the following error message:
MSN, 1253, The network provided is not allowed for specified publisher countries., en_US
This message will appear within the Activity Log when you click on the Activity ID, and also within the downloaded error file which you can retrieve from the Activity Log row containing the failed upload.
What Causes The Issue?
This error message is related to the Network setting on Microsoft Advertising at the group level. This error appears to be due to an issue on the publisher’s side, and is not a result of any platform error.
How To Fix The Issue
To avoid this error, all Microsoft Advertising groups need to target both Search and Search Partners. Groups that are targeting Language=English and Geo Target=US can target Search only, without including Search Partners, but all other groups will need to target Search Partners to avoid this error.
If you correct the issues above and are still running into this error, you can try deleting the campaign from the platform and recreating it, then uploading it again.
If none of these solutions work for you, please contact our Customer Support team.
