why some users not inheriting email address policy?

So, we have a default policy that's being applied to all of our users but now that we are about to migrate those mailboxes to O365 i have realized that they don't have the proxy smtp address of domain.mail.onmicrosoft.com stamped.

Like I have mentioned that we do have a default policy with the following email address format:

SMTP @domain.com

smtp alias@domain.mail.onmicrosoft.com

so, why is this the case for 200 users and not the other 3000 users?

Thanks,

What is set for an account that isnt updated?
Make sure this checked under Email Addresses in EAC

If not, update all the users and apply the policy
https://docs.microsoft.com/en-us/exchange/email-addresses-and-address-books/email-address-policies/eap-procedures?view=exchserver-2019#apply-email-address-policies-to-recipients

Exchange Powershell:

 get-mailbox |FL EmailAddressPolicyEnabled

 set-mailbox <user>  -EmailAddressPolicyEnabled $true

In Bulk:

 Get-Mailbox  | ?{$_.EmailAddressPolicyEnabled -eq $False} | Set-Mailbox -EmailAddressPolicyEnabled $True

Did you see my answer? :)
Are their accounts enabled to automatically update their email addresses?
If so, and it didnt get applied, then apply per that doc.

After you create or modify an email address policy in the EAC or the Exchange Management Shell, you need to apply the policy to the affected recipients.

@Safs-3080

If you uncheck the "Automatically update email addresses based on the email address policy applied to this recipient" before creating an email address policy, this email address policy will not apply on this mailbox.

So, in your organization, this setting is unchecked on those mailboxes before creating hybrid.

You just need to enable this setting on those mailboxes again, the proxy email address will show on those mailboxes.
