Dbmail the Client Was Not Authenticated Office 365 Login

If you are an Office 365 customer there are a number of steps you need to configure to ship mail notifications from your applications or Unitrends Appliance to your Office365 domain mailboxes. First off you won't forget to backup your Function 365 environment, right?

Function 365 supports these options for sending email from an awarding:

1. Authenticate your device or application directly with an Role 365 mailbox (SMTP customer submission)
2. Ship mail direct from your printer or application to Office 365 (Directly ship)
3. Configure a connector to transport mail using Office 365 (SMTP relay)

Unitrends appliance currently cant apply choice Pick one out of the box.

And then in this web log post we volition explain how to employ Option 2 (Direct Send) and Option 3 (SMTP Relay) and the differences.

Direct Send

If you but want to ship mail alerts and reports to your Office365 mailboxes this method is the easiest one equally you dont have to configure annihilation else in Office365. But it will non work for sending mails to external mail addresses like user@gmail.com or other domains.

To configure, you only need to find out the MX DNS register for your domain and setup it in your application settings.

You tin find it using powershell:

PS> Resolve-DnsName -Proper noun unitrends.com -Type MX  Proper name                                     Type   TTL   Department    NameExchange                              Preference ----                                     ----   ---   -------    ------------                              ---------- unitrends.com                            MX     ix     Answer     unitrends-com.mail.protection.outlook.com 0

In this scenario to send alerts to our @unitrends.com user mailboxes we just need to configure unitrends-com.mail service.protection.outlook.com as SMTP.

And that is all! Now you should be able to receive notifications in your Office365 mailboxes from your appliance or applications.

SMTP Relay

This method allows to send postal service to other domains but it requires your Office365 ambassador to create a mail flow connector that allows relay all mails that are coming from the public IP address used by the appliance to connect to Office365.

[root@ueb08 ~]# ringlet -due south icanhazip.com 37.134.134.124 [root@ueb08 ~]# curl -s curlmyip.com 37.134.134.124 [root@ueb08 ~]# whorl wgetip.com 37.134.134.124 [root@ueb08 ~]# curl -s wgetip.com 37.134.134.124
