Unknown To address

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

  *   Send the message again following these steps: In Outlook, open this non-delivery report (NDR) and choose Send Again from the Report ribbon. In Outlook on the web, select this NDR, then select the link "To send this message again, click here." Then delete and retype the entire recipient address. If prompted with an Auto-Complete List suggestion don't select it. After typing the complete address, click Send.
  *   Contact the recipient (by phone, for example) to check that the address exists and is correct.
  *   The recipient may have set up email forwarding to an incorrect address. Ask them to check that any forwarding they've set up is working correctly.
  *   Clear the recipient Auto-Complete List in Outlook or Outlook on the web by following the steps in this article: Fix email delivery issues for error code 5.1.1 in Office 365<https://go.microsoft.com/fwlink/?LinkId=389363>, and then send the message again. Retype the entire recipient address before selecting Send.

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 5.1.1

This error occurs because the sender sent a message to an email address outside of Office 365, but the address is incorrect or doesn't exist at the destination domain. The error is reported by the recipient domain's email server, but most often it must be fixed by the person who sent the message. If the steps in the How to Fix It section above don't fix the problem, and you're the email admin for the recipient, try one or more of the following:

The email address exists and is correct - Confirm that the recipient address exists, is correct, and is accepting messages.

Synchronize your directories - If you have a hybrid environment and are using directory synchronization make sure the recipient's email address is synced correctly in both Office 365 and in your on-premises directory.

Errant forwarding rule - Check for forwarding rules that aren't behaving as expected. Forwarding can be set up by an admin via mail flow rules or mailbox forwarding address settings, or by the recipient via the Inbox Rules feature.

Mail flow settings and MX records are not correct - Misconfigured mail flow or MX record settings can cause this error. Check your Office 365 mail flow settings to make sure your domain and any mail flow connectors are set up correctly. Also, work with your domain registrar to make sure the MX records for your domain are configured correctly.

Dagsljuskraven i Boverkets nya byggregler

Kurs om hur man hanterar de nya kraven på dagsljus i byggnader och

vad de innebär för tillsyn, byggnadsutformning och användbarhet.

[https://post.nuhet.se/images/public/19812_d32b6ce414d6c2136337b111ba2ac9b5.JPG]

KRAV MED HELT NY METODIK
De nya dagsljuskraven regleras i föreskriften Hygien, hälsa och miljö. Metodiken är annorlunda än tidigare och ger på samma gång skärpta krav som större friheter beroende på byggnadens förutsättningar.

DU LÄR DIG
På kursen går vi igenom de nya kraven och fördjupar oss i hur det ska tolkas och tillämpas. I sammanhanget redogör vi för vilka standarder och branschöverenskommelser som kan hänvisas till i projektering och tillsyn. Tillsammans diskuterar vi vad förändringarna kan komma att innebära för arbetsinsats, byggnadsutformning, användbarhet och hälsoaspekter.

MÅLGRUPP
Kursen vänder sig till dig som kommer i kontakt med dagsljusfrågor i projektering och tillsyn, det vill säga dagsljusexperter, arkitekter, byggnadsnämnder, energi- och inneklimatexperter med flera.

KURSLEDARE
Helena Bülow-Hübe är en av landets ledande dagsljusexperter och arbetar till vardags som energi- och miljöchef på FOJAB. I utvecklingsarbetet med de nya byggreglerna verkade Helena som sakkunnig för Boverkets räkning.

Välkommen på kurs!
