How do I terminate my mailbox account

Termination via the Homepage

You can also terminate your contract directly via our homepage. To do this, go to the mailbox homepage and click on Terminate contracts here. There you must fill out the provided termination form and confirm your details. Then follow the further steps to complete the termination. You can access the homepage at the following link:

Figure 1: Scroll to the bottom of the homepage to find the termination form.


Figure 2: Fill out the termination form and confirm your entries.

In general, terminating your account is not necessary, since you have a fixed contract term according to your payment and your chosen plan. However, you can terminate at the end of each billing month. We will soon implement the termination function in mailbox Office.

Once the contract term has expired and you do not actively extend the contract, it will automatically be terminated. The end of the term can be found in your current contract. A monetary refund or reimbursement of the remaining term is not possible. Should you still wish to terminate, you can do so at the end of the respective month. We will then delete all your data.

Can we improve something?

We regret that you would like to terminate your mailbox account. Perhaps we can still do something for you or at least improve our service for the future. Is there anything that could be improved in support, or do you have further suggestions and wishes? We would be happy to assist you in resolving any issues.

If you would like to change your primary address, please do not terminate. Instead, simply create a new alias. You can then set this alias as your primary address and keep the account with all data and settings. If you terminate your account, your primary address (@mailbox.org) and any aliases will remain blocked for at least 90 days – the blocking period depends on the plan and the age of the account. From that point on, you will no longer be able to log in with these mail addresses – we also protect you from identity theft this way.
