Hi,

We are trying to reassign a license to one of our old employee who left the organization quite a time ago, but now when we assign him a license his mailbox is not being generated and so we cannot access his mailbox.

it gives this error message in the admin center.

Exchange: The proxy address "SPO:SPO_e7203c8c-4f28-4835-bd30-8de149f6fb20@SPO_d947c0a8-4566-41f8-8bb4-f5da7c416b7e" is already being used by <name of an another employee>

whereas when we try to login to office portal it just throws back with the message saying "something went wrong"

Hello Irfan,

May I confirm if your organization is purely Exchange Online? Generally, this error occurs because an object has the same proxy address already exists in Exchange Online. Therefore, you can try to change this user’s proxy address or remove the conflict address.

For more information about how to do it, here for your reference: "Proxy address is already being used" error message in Exchange Online

I hope this can help. If this is not your scenario, please feel free to let me know.

Best Regards,

Sylvie
