We are happy to report that there have been no reported cases of rejections in the last two days. We continue to monitor the situation, while Microsoft is actively working to fully resolve the issue.
The error has not been completely resolved, but the number of rejections should be considerably reduced. Microsoft continues to work with third-party anti-spam services to unblock affected IP addresses.

Some customers are currently experiencing intermittent issues with receiving invoices via email to SEMINE. After thorough investigation, we have identified that certain sender IP addresses are currently being blocked by spam filters used by multiple email providers.
The cause of this issue lies in the blacklisting of IP addresses associated with Microsoft Outlook 365 servers. You can read more about the problem here. This is a global issue affecting several email providers. Email servers with IP addresses from this block (40.107.XXX.XXX) will be rejected until the problem is resolved.
It is important to note that all vendors affected by this issue will receive a notification that their invoice was not received by you as a customer. However, if you are aware of invoices received via email that are not present in SEMINE, we recommend manually uploading the affected invoices.
Microsoft is actively working to resolve this issue and prioritizing the removal of IP addresses from the spam list. We will keep you updated on the progress, with the latest information in this article.
In the meantime, we appreciate your patience and apologize for any inconvenience this may cause.
Actions you can take as a customer now:
- Manual Upload: Manually upload affected invoices in SEMINE for immediate processing.
- Stay Informed: Keep an eye on our updates regarding this issue for the latest developments.
