Frequently asked questions about e-mail archiving

E-mail archiving is a legal requirement for many companies. We answer the key questions and implement the right solution for you.

Who must archive e-mails?

All merchants within the meaning of the German Commercial Code are obliged to archive – that is, partnerships and corporations. E-mails relevant for tax purposes (GoBD) must also be retained in unalterable form.

How long must e-mails be retained?

Commercial and business letters: 6 years. Accounting documents and tax-relevant correspondence: 10 years. The retention period begins at the end of the calendar year in which the document was created.

Was bedeutet GoBD-konform?

The GoBD (German principles for the proper keeping and retention of books) require completeness, accuracy, immutability and traceability. E-mails must be stored in their original form and remain legible at all times.

What happens if archiving is missing?

During a tax audit the tax office may estimate profits if the bookkeeping is deficient. Penalties, back payments and fines can be the result.

Which e-mails must be archived?

All e-mails received and sent with business content – in particular quotes, order confirmations, invoices, reminders and contract correspondence. This also includes e-mails with PDF attachments (e.g. electronic invoices).

Wie funktioniert MailStore?

MailStore archives e-mails automatically directly from the mail server (Exchange, Microsoft 365, IMAP). All e-mails are compressed, deduplicated and stored unalterably – fully searchable for staff and auditors.

Cloud or on-premises?

MailStore is available both as an on-premises solution (your own server) and as a Service Edition (hosted). PROXYTEC advises you on which variant suits your infrastructure and requirements.
