Unknown To address

How to Fix It
The email address might be misspelled or it might not exist. Try one or more of the following:

  *   Retype the recipient's address, then resend the message - If you're using Outlook, open this non-delivery report message and click Send Again from the menu or ribbon. In Outlook on the web, select this message, and then click the "To send this message again, click here." link located just above the message preview window. In the To or Cc line, delete and then retype the entire recipient's address (ignore any address suggestions). After typing the complete address, click Send to resend the message. If you're using an email program other than Outlook or Outlook on the web, follow its standard way for resending a message. Just be sure to delete and retype the recipient's entire address before resending it.
  *   Remove the recipient from the recipient Auto-Complete List, then resend the message - If you're using Outlook or Outlook on the web, follow the steps in the "Remove the recipient from the recipient Auto-Complete List" section of this article<https://go.microsoft.com/fwlink/?LinkId=532972>. Then resend the message. Be sure to delete and retype the recipient's entire address before clicking Send.
  *   Contact the recipient by some other means, (by phone, for example) to confirm you're using the right address. Ask them if they've set up an email forwarding rule that could be forwarding your message to an incorrect address.

If the problem continues, forward this message to your email admin. If you're an email admin, refer to the More Info for Email Admins section below.

More Info for Email Admins
Status code: 550 5.1.351

When Office 365 tried to send the message, the external email server returned an error stating that the recipient is unknown or the mailbox is unavailable. This error was reported by an email server outside Office 365.

If you or the sender can't fix the problem, contact the responsible party's email admin - Give them the error code and error message from this non-delivery report (NDR) to help them troubleshoot the issue. To determine who the responsible party might be, check the error for information about where the problem is happening. For example, look for a domain name like contoso.com. A domain name in the error might suggest who is responsible for the error. It could be the recipient's email server, or it could be a third-party service that your organization or the recipient's organization is using to process or filter email messages.

Although the sender might be able to fix the issue by correcting the recipient address, it's likely that only the recipient's email admin can fix the problem. Unfortunately, it's unlikely Office 365 Support will be able to help with these kinds of externally reported errors.

Ny värmepump med fokus på prestanda och livslängd
Kurs om hur värmepumpar installeras för att hålla projekterad prestanda med tillåtna köldmedier under sin tekniska livslängd. Vid ersättning eller komplettering av fjärrvärme, värmepanna eller befintlig värmepump.

Ökat intresse för värmepumpar
Allt fler fastighetsägare funderar på att installera värmepump som ersättning eller komplettering till befintliga värmepannor och numera även fjärrvärmecentraler på grund av de kraftiga prisökningarna. Är förutsättningarna de rätta ger det inte bara bättre driftsekonomi utan också bättre energiklassning och ökat fastighetsvärde.

Byggnadens tekniska förutsättningar
Men vilka är då rätt förutsättningar? Byggnaden och dess installationssystem påverkar i stor utsträckning värmepumpens verkliga prestanda. När är det möjligt och när är det inte möjligt eller att rekommendera en nyinstallation? I kursen gör vi en djupdykning i alla tekniska parametrar som är avgörande för prestanda och driftsäkerhet.

Installation med fokus på prestanda
Mest tid ägnas åt att gå igenom alla steg från systemval, upphandling och installation till driftsättning och uppföljning, med målsättningen att värmepumpen ska hålla projekterad prestanda med tillåtna köldmedier under sin tekniska livslängd. Vidare lär du dig göra en realistisk ekonomisk kalkyl som beslutsunderlag. Stort utrymme får också hållbarhetsfrågor.

Erfaren kursledare
Johan Bursell har arbetat med värme- och kylinstallationer i hela sitt yrkesliv; på större konsultbolag, på energibolag och sedan några år i egen verksamhet. Hans erfarenhet omfattar anläggningar i kontorsfastigheter, bostadshus, industri, serverhallar, simhallar, storkök, äldrevård och skolor.
