How to Fix It
When Office 365 tried to send your message to the next server outside Office 365, that server reported an error that it couldn't relay your message. It's likely that the email server isn't correctly set up to receive and relay messages from your organization.
To fix this issue, forward this non-delivery report (NDR) to your email admin.

More Info for Email Admins
Status code: 550 5.7.367

The sender's message was routed to an email server outside Office 365 that returned an error that it can't relay the message. It's likely that the server isn't set up correctly to receive and relay messages sent from post.nuhet.se or from 19812_4723_667524_bounce.

The receiving server is not an Office 365 server - it's likely one of your on-premises servers in a hybrid environment, a server at a smart host email service that you're trying to route messages through, or possibly a server at an email hosting service you used in the past (for example, when your MX record still points to your previous email service provider). To fix this issue, try one or more of the following:

Check the error shown in the "Error Details" section below - Check the error to determine what domain, service, or server is reporting the error. The email server needs to be configured to either accept messages from anonymous users or to include the sending domain or sending IP address in its list of authenticated senders. On an on-premises Exchange server, you can set this up in the server's receive connector. If it's a smart host managed by another service or partner, contact the service or partner and ask them to configure their servers to accept and relay messages from your domain or from your senders.

Make sure your MX/DNS records are correct - Work with your DNS hosting provider (your domain registrar, Web hosting provider, or ISP) to make sure your MX records are correctly set up to direct messages to the correct location.

Unfortunately, Office 365 support can't help fix this problem because it's likely due to misconfigured settings on an email server outside Office 365.

Legionella och energiförluster i tappvattensystemKurs om hur man förebygger och hanterar utbrott av legionella samt 
hur energiförluster minskas i nya respektive befintliga tappvattensystem. I kursen fokuserar vi på hur man förebygger legionella och hanterar utbrott om olyckan är framme. Eftersom förutsättningarna för legionella har en koppling till systemens energieffektivitet har vi slagit ihop frågorna i en och samma utbildning. Du lär dig vad legionella är, hur man mäter förekomsten, hur man minimerar riskerna och bekämpar utbrott. Vi går också igenom gällande lagstiftning som innebär stort ansvar för fastighetsägare. Energiförluster från tappvattensystem är ofta höga och en viktig förklaring är att dessa nästan alltid uppskattas med schablonvärde i projektering. I kursen lär du dig hur man mäter och beräknar förluster. Med fokus på VVC går vi igenom vilka åtgärder som kan vidtas i befintliga system och hur man styr upp såväl projektering som utförande i nybyggnad. Kursledare är Jonatan von Seth, en av landets ledande experter inom området.
