Office 365 – Can not receive mails with ownen Mail Domain

office365

After working with some test accounts in Microsoft Office 365 I realized I could not send mails to my own domain. In the Office 365 control panel everything looked right and the domain was active. I also added the mail addresses to the user accounts.

The error I got back was:

Final-Recipient: rfc822;[email protected] Action: failed Status: 5.4.1 Diagnostic-Code: smtp;550 5.4.1 Relay Access Denied

After creating a support ticket with the Microsoft Office 365 the support called me and checked my account. Now the problem was I already added the domain to another Office 356 account. So the Forefront had the domain added as duplicated domain.

 Office 365 Forefront

 You can check the status of your domains in Forefront by clicking on the Exchange Online Administration (Manage) like on the Overview site. Now you can click

Now on your Exchange Online Management page click on Mail Control on the left site.

On the right site you can click on Configure IP safelisting, perimeter message tracing, and e-mail policies.

Now in the Domain tap you can check if you have a domain entry whichs starts with “duplicated…..”. If you have a entry like that you have to open a support ticket and the Forefront Online Team will remove the entry from your Account and you have to add the Domain again.

By the way this was the first time I used the Microsoft Support for Office 365 and it was a really good experience. Microsoft really offers a great Service here with fast and qualified support.

 



Office 365 important DNS knowledge

Last week Microsoft launched Office 365. Office365 is clearly a great product. Microsoft offers three different “plans”. One is for small businesses, Plan P, maybe stands for Professional or Personal. Plan P is a offer for small businesses with less than 26 users. For bigger companies or Enterprises Microsoft offers Plan E (Enterprise) which also includes Plan K (kiosk workers).

Now there are a lot of differences between this plans which are described on the Office365 website. But there is something I just realized after I used Office 365 the first time. If you want to use Office 365 with your own domain, Microsoft has two ways to do this.

With Plan P you have to delegate all the DNS configuration to Microsofts DNS servers, which means your DNS servers for your domain, will be somednsserver.microsoft.com. Microsoft offers you a simple UI to create additional CNAME and A records. And all your MX records and A records which are used by Office 365 will be created automatically. This makes it very easy, but even for some small businesses this does not work, because they may need more than just some simple additional A records or CNAMEs.

If you wanna use your own DNS servers or the DNS servers of your provider, you have to use one of the Enterprise plans (there are more than one plan). With a Plan E1 for example, you can choose to delegate all the DNS administration to the Microsoft DNS servers or you can choose your own, maybe already existing public DNS servers. In this case Microsoft tells you which DNS records you need to create (MX, TXT and A records).



Microsoft Office 365

In the last days I started to work with the Microsoft beta of Office 365. After testing it for a while I think this could be a great solution for small & medium businesses. And its a really hard competitor to Google Apps. There are a lot of advantage which Office 365 has agains Google Apps and I think because it is a Microsoft Solution for a lot of companys this is the better way to go, if they already used Microsoft Products or have a Microsoft enviroment.

  • More options and features instead of  Google Apps, for example in Exchange or Forfront which protects Exchange and SharePoint Online for free.
  • Microsoft Solutions – the most people and companys already use them.
  • Powershell – This is a really cool feature. You can administrate  the whole Office365 online serivce with Windows Powershell.

In the next few weeks I will post some blog post about how to use Office 365 and some Powershell How To posts.
