Testing Office 365 SMTP relay
In order to test Office 365 SMTP relay you will have to create a user with an Exchange online license. After the email is activated for this user you can test this user for relay with the following powershell.
First connect to Microsoft Online service with this user that you’ll be using for relaying.
$msolcred = Get-Credential
Next edit the following powershell with the user’s e-mail and the recipient’s too
Send-MailMessage –From RelaySMTPuser@domain.com –To destinationuser@gmail.com –Subject “Test Email” –Body “Test SMTP Relay Service” -SmtpServersmtp.office365.com -Credential $msolcred -UseSsl -Port 587

This test is known as Client SMTP submission you can also use a different method for multiple devices where you can configure them all to point to a single server (IIS) in a method known as IIS for relay with Office 365 however, all the methods what involve office 365 (Only) for relay will require a user with Exchange online license assigned to it.

If you have configured Hybrid integration between Exchange 2010/2013 with Office 365 using dirSnyc or Azure active directory sync tool and then stopped the synchronization. The accepted domains and additional domains will be removed from the user’s Attributes on the cloud and in order to add these accepted domains again to all of the Office 365 users..
First we’ll have to connect to Exchange online with the following powershell tool. so Launch Azure powershell as Admin and copy the following line by line.
1- $UserCredential = Get-Credential
2- $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUrihttps://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
3- Import-PSSession $Session
First we’ll show/view user’s existing SMTP addresses, in order to do so we’ll use the following PowerShell cmdlet
For all users
4- Get-Mailbox | fl –property Alias, WindowsLiveID, EmailAddresses
For one user
Get-Mailbox –Identity user@domain.com | fl –property Alias, WindowsLiveID, EmailAddresses
Procedure to add an additional accepted domain to all users in the Office 365 tenant.
Note:
The domain must be verified on Office 365 first before applying those steps
1-
$users = Get-Mailbox
2-
foreach ($a in $users) {$a.emailaddresses.add(“smtp:$($a.alias)@AdditionalDomain.com”)}
3-
$users | %{Set-Mailbox $_.Identity -WindowsEmailAddress $_.WindowsEmailAddress}
