Is it possible to connect only one profile through DNS connection

Hi,

We are a small business which I am the only user of the office package.

Is it possible to only have my email connected to Outlook with DNS-setup in with the domain holder?

Because when following your step-by-step guide, you recieve "can't be found"-messages when mailing the others in the organization. Which makes sense when the string of "autodiscover" is set in the domain-holders DNS settings.

Hi @MrtenLeanders-7627,
Welcome to Q&A forum!
According to your description, I will remove the tag office-itpro that focuses on general issues about Office desktop applications, and add tag office-exchange-server-connectivity for you.
Thanks for your understanding.

Hi @MrtenLeanders-7627

To better understand your question, I would like to first confirm with you:

We are a small business which I am the only user of the office package.

Since you mentioned you are the only user of the office package, are you using Exchange Online (Office 365) for email service?

Because when following your step-by-step guide, you recieve "can't be found"-messages when mailing the others in the organization.

1.Which guide did you follow? Can you provide a link if possible?
2.What email service are others in your organization using? Do they have trouble with sending emails to your mailbox?

Which makes sense when the string of "autodiscover" is set in the domain-holders DNS settings.

What records have you set in the local DNS?
Do you have a CNAME record of autodiscover.yourdomain.com to point to autodiscover.outlook.com?

Hi, first of all thank you for taking the time to answer.

We have our domain at one.com but I would like to have everything in the office package with outlook to be able to quickly save attachments and publish general documents in a small database and cloud service with onedrive. Today we are using one.com webmail.

  1. So the problem occur when I'm following the guide for adding DNS-Posts. See link. https://docs.microsoft.com/en-us/microsoft-365/admin/get-help-with-domains/create-dns-records-at-any-dns-hosting-provider?view=o365-worldwide

  2. Others are using the webmail from One.com.
    And for me it works fine, but since the other two in the business doesn't have an office user that is within the exchange server whoever sends an email to them gets a autoreply such as:
    "Your message to firstname.lastname@nvvsp.se couldn't be delivered.
    firstname.lastname wasn't found at nvvsp.se."

I set the records that was mentioned in the step by step guide in the link above.

Hi @MrtenLeanders-7627

Thanks for the information and clarification!
While I suppose it may be the expected behavior.

As if you add a MX record to Exchange Online with higher priority or have removed other MX records , the emails sent to your domain would all be sent to Exchange Online.
And since your colleagues' mailboxes are actually hosted by one.com, they don't have mailboxes in Exchange Online, thus the senders cannot find their mailboxes and would receive the "Your message to firstname.lastname@nvvsp.se couldn't be delivered" NDR message.

A workaround I could think of is to change your domain in Exchange Online from Authoritative to Internal Relay, which would deal with the recipients that are not hosted by Exchange Online instead of rejecting the messages directly.
More information about Authoritative and Internal Relay domain are introduced in this link: Manage accepted domains in Exchange Online

The general steps would be:
1.change the domain to Internal Relay
2.create a connector to relay emails sent to your colleagues to one.com

Here is also an article introducing a similar scenario for your reference: Configure Email Coexistence between Office 365 & Google Apps
It uses the classic Exchange Admin Center but should also apply to your situation.

Hi I haven't had the time to check. But I looked in to it. And I think that would solve the case. But I don't know. Otherwise I will have to check with someone more experienced.
