When Azure AD Connect it configure to sync ad account to Azure AD/Office 365 it assigns the login name as the AD UPN (as expected), but it won’t assign that same UPN as the default email address – instead it assign a @mydomain.onmicrosoft.com as the primary email address.
to correct this we can use the Synchronization rules editor, which is installed together with the Azure AD Connect (Download Link)
In Synchronization rules editor, switch the direction tabs to outbound rules.
select the rule called “Out to ADD – UserExchangeOnline”, click edit and accept the option to disable and clone the rule (this will create a rule called ““Out to ADD – UserExchangeOnline – Cloned” that can be modified.
Change the precedence to 50
go to transformations, and Scroll down till you find the “Target Attribute” of “ProxyAddresses”
Change the FlowType to “Expressions” and enter the following in the source:
"SMTP:" & [userPrincipalName]
Now resync the users and the primary email address should be changed

Remove password expiration Office 365
I wrote this powershell script to remove password expiration for all users, so that the users password not expires
Password_expiration.ps1
$Cred = Get-Credential Read-Host 'Press Enter to continue to Connect to Office 365' | Out-Null Write-Host "Continueing..." $s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic –AllowRedirection Import-PSSession $s Read-Host 'Press Enter to continue to remove password from expires for all users' | Out-Null Write-Host "Continueing..." Connect-MsolService –Credential $cred Get-MSOLUser | Set-MsolUser -PasswordNeverExpires $true Read-Host 'Press Enter to exit script, All Done' | Out-Null
Change Retention Policy – Office 365
I wrote this powershell script to remove the Retention Policy that delete all emails in Users Deleted Items folder that are older then 30 days
Retention_Policy.ps1
$Cred = Get-Credential Read-Host 'Press Enter to continue to Connect to Office 365' | Out-Null Write-Host "Continueing..." $s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic –AllowRedirection Import-PSSession $s Read-Host 'Press Enter to continue to Remove 30 days Deleted Items rule' | Out-Null Write-Host "Continueing..." Enable-OrganizationCustomization Set-RetentionPolicyTag "Deleted Items" -RetentionEnabled $false Read-Host 'Press Enter to exit script, All Done' | Out-Null
Create office 365 mail relay connector
go to https://outlook.office365.com/ecp/ login as global administrator
step 1: click Mailflow
step 2: click Connectors
step 3: click Add
step 4: Give the connector a name (eg. AllowRelay)
step 5: Select On-Premise
step 6: Select Restrict domains by IP addresses
step 7: Set sender domain to *
step 8: Set sender ip to your own Wan ip/public ip (Only static ips is allowed)
step 9: Set Accepted domains to your office 365 domain
now you can use your own mx record eg. youdomain-com.mail.protection.outlook.com as relay server/smarthost without login, and on port 25
