Manually migrate Distribution list from on-prem to cloud (Workaround)


Ø Delete Distribution List from On-Prem Exchange and recreate it in O365 

Ø Create an account in On-Prem AD with same display name

Ø Enable that account in on-premise Exchange as Mail-User and assign primary SMTP email address as oceanspray.mail.onmicrosoft.com

 Enable-mailuser  -identity Test_Onpremise2 -ExternalEmailAddress Test_OnPremise2@xyz.mail.onmicrosoft.com


Ø Open that account in on-premise Exchange and add new email address

Test_OnPremise2@xyz.onmicrosoft.com

 

Ø In O365 open properties of that DL and add new email address

Test_OnPremise2@xyz.mail.onmicrosoft.com
