Hi,

I have a hybrid setup with Office 365 and one exchange 2013 standard server on-premises.

I currently have an issue with that I have a button after pressing the + under recipient to create a Office 365 mailbox from the ECP, but users that are members of the Recipient Management role don't have that button visible.

What extra permissions are required to be able to create an Office 365 mailbox from the on-premises Exchange?

You should be creating a remote mailbox in the on-premises organization, not a mailbox in the Office 365 organization.

Hi,

I suggest also add the users into Organization Management role for testing.

Since Office 365 is different from Exchange On-Premises. I suggest ask Office 365 forum to double confirm this issue. For your convenience:

Thanks

If I put my test user in the Organization Management role, then the Office 365 Mailbox button appears.

So some role gives the permission to see and click that button, but I can't figure out which one it is.

Hi SeidKrv,

Thanks for your update.

Following article introuduces the permissions that need to assigned before running "New-Mailbox" command.

Please focus on "Recipient Provisioning Permissions" session.

Recipients Permissions

Based on the article, it seems both Recipient Management role and Organization Management role are required.

More detailed information on both management role as below:

1. Administrators who are members of the Recipient Management role group have administrative access to create or modify Exchange 2013 recipients within the Exchange 2013 organization.

2. Administrators that are members of the Organization Management role group have administrative access to the entire Exchange 2013 organization and can perform almost any task against any Exchange 2013 object, with some exceptions. By default, members of this role group can't perform mailbox searches and management of unscoped top-level management roles.

 

Thanks

Are you sure about that answer?  Organization Management is listed for every feature, but clearly you don't have to be in Organization Management to do many of them, like basic recipient management tasks.  I think it's an either-or.
