Hi all,
I have some small issue with proxyAddresses,
Some time ago we connect our AD to Azure all is good with syncro, but is some issue to sent information from Azure to Exchange online.
In AD on-permise I put smpt and SMPT proxyAddress atribute, next this is synchronized to Azure, and on Azure side all is good too, the same value like in AD. Only when I opened mailbox in Exchange admin panel I see some weird things.
Example:
AD
SMTP: daomain.pl
smtp:domain.onmicrosoft.com
Azure:
SMTP: daomain.pl
smtp:domain.onmicrosoft.com
Mailbox in Exchange online
smtp: daomain.pl
SMTP:domain.onmicrosoft.com
In this fact my primary email address is with "onmicrosoft.com"
How to fix this, someone know?
I saw some powershell tutorial, but doing this trought PS for 500 accounts now and for evry new one is bad way I think, when we have full synchro and correct proxyAddress atribute in AD

It is indeed weird, Exchange Online should reflect the same attributes for Azure AD.
Could you verify the following:
- On Azure AD do the accounts show as on-prem synchronized?
- Are you on a Exchange Hybrid setup?
Regards,
Said,

Are you running in an Exchange Hybrid environment with the mailboxes still hosted in on-premises Exchange?
And this is affecting all the user accounts, right?
If possible, could you share the "powershell tutorial" you saw so that we can understand better about your situation?Besides, please make sure daomain.pl has already been verified in Microsoft 365 and configured as accepted domain in Exchange Online.
