Answers for private customers

The Knowledge Base for private customers is already largely up to date. A few individual articles are currently being revised and will be updated shortly. We thank you for your understanding and look forward to providing you with the latest information on using mailbox.

Please note: The Knowledge Base has changed slightly. Categories have been adjusted and any URLs stored in the old Knowledge Base are no longer valid.

More storage space for mailbox

You can customise the storage space for your mailbox-Office to suit your individual needs. To do this, log in to your mailbox Office. Go to Settings and select Contract and payment (1) and then Contract (2). Here you can now get additional storage (3).


Figure 1: Under the heading Contract and payment, you can quickly and easily change your email and cloud storage settings.

You can flexibly expand the available additional storage for Mail (4) and Cloud (5), but also reduce it again.
Confirm the terms and conditions and the cancellation policy. Then click on Order with obligation to pay (6).


Figure 2: Customise your mail and cloud storage requirements to your personal needs.

Change of Plan

In the Change Plan section, you can change your Plan quickly and easily. You can switch to one of the other available Plans at any time. You can decide whether you prefer annual or monthly billing. Once you have selected your plan, click on Order with obligation to pay (7).


Figure 3: Select the Plan that best suits your needs.

Once you have decided on a new Plan, a partial refund will automatically be made for the old Plan. So, for example, if you have only used the Standard Plan for half a month, you will be charged 1,25 € and the remaining amount will be credited to your account. When you change your plan, any unused credit will be credited to your mailbox account - therefore, you cannot lose any money.
In your dashboard, you will find the Storage widget, where you can see how much storage space has already been used. This makes it easy to keep track of things!
