Assigning an Administrator User for Microsoft Exchange 2013
In this article, we'll show you how to set up or change the administrator user for your Microsoft Exchange 2013 accounts. The administrator can assign other mailboxes read and write permissions to public folders, as well as create, edit, and delete resource mailboxes.
Log in to your IONOS account.
In the product overview, click on the Email tile.
If necessary, select the contract in which the Microsoft Exchange 2013 accounts are set up.
Next to the desired email address, click Set Administrator in the Actions section.
In the Administrator list, select the mailbox to which you want to assign the administrator role and click Save.
Assignment may take a few minutes. Once it is complete, you will find a corresponding entry in the mailbox overview.
Note
The Administrator role can only be assigned to one mailbox. However, you can assign it to another mailbox at any time later by repeating this step.
