Frequently Asked Questions

Everything you should know before buying

Case law on used software

As the highest judicial authority of the European Union, the Court of Justice of the European Union (CJEU) provided final clarity with its ruling and declared the trading of used computer programs fundamentally lawful.

The CJEU also ruled that trading in used software is permissible even when the software is transferred online.

On July 17, 2013, the Federal Court of Justice fully confirmed the CJEU’s landmark decision with regard to the underlying legal questions. 

The CJEU ruling also applies to volume licenses and their splitting. This was confirmed by the Higher Regional Court of Frankfurt am Main in proceedings between Adobe and usedSoft.

In their reasoning, the 13 judges of the Grand Chamber clearly established that the exhaustion principle applies to every first sale of software. The CJEU even ruled that a subsequent purchaser may download the software again from the manufacturer in the case of licenses transferred online: “Furthermore, the exhaustion of the distribution right extends to the program copy in the version improved and updated by the copyright holder,” the CJEU stated. The Court thus went significantly beyond the opinion of the CJEU Advocate General of April 24, 2012.

VOLUME LICENSES AND THEIR SPLITTING ALSO LEGAL

In a later ruling by the Higher Regional Court of Frankfurt am Main in proceedings between Adobe and usedSoft, the further implications of the CJEU ruling were impressively confirmed: The Frankfurt Higher Regional Court held that the CJEU ruling also applies to volume license agreements and their splitting. The Federal Court of Justice dismissed Adobe’s appeal in its entirety on December 11, 2014 (Case No. I ZR 8/13). This conclusively confirmed the Frankfurt Higher Regional Court’s ruling.

Microsoft Outlook 2021 for Windows

Order Microsoft Outlook 2021 from Officekey24

At 1A-Lizenz, you can purchase Microsoft Outlook 2021 affordably and securely. This powerful email management software is available for download immediately after purchase. Get started right away with this popular application, which helps you organize your communication efficiently.

Versatile features of Outlook 2021

Outlook 2021 goes far beyond simply sending and receiving emails. This versatile application offers numerous features developed specifically for professional users. Particular emphasis is placed on ease of use and security, both of which are highly important today.

Given the constantly growing threat posed by malicious emails, it is essential to use a secure email client. Outlook 2021 includes an integrated scanner that checks all attachments in incoming emails. If a potentially dangerous attachment is detected, the software removes it immediately before it becomes accessible to the user. Outlook also analyzes links in emails and warns you about potential risks.

The software supports all common email providers, so you do not necessarily need a Microsoft account. In addition, multiple email accounts can be managed through a clear user interface, saving you valuable time in everyday use. Outlook 2021 also offers advanced encryption for securely transmitting data when sending emails.

Advantages of purchasing Outlook 2021

By purchasing Outlook 2021, you benefit from a wide range of features that optimize the way you work. The purchased version provides storage for up to 50 terabytes of emails—more than enough for long-term use. Microsoft also provides you with 1 terabyte of cloud storage through OneDrive, which you can use for all types of documents. In addition to the desktop version, you can use the Outlook app in the cloud by simply signing in through a web browser. The app is also available free of charge for mobile devices running iOS and Android.

Improvements in Outlook 2021

Outlook 2021, the direct successor to Outlook 2019, introduces several subtle yet useful improvements. The design has been slightly updated to provide a more appealing and modern user interface, particularly tailored to Windows 11. Performance has also been optimized, so you can expect a more stable application that works better, especially on older systems.

A new writing assistant helps you compose messages, while the improved search function makes it easier to find information. You can also share messages directly with other users through Outlook 2021, greatly simplifying collaboration. This requires the free "Teams" software, which is already included in many Office packages.

A wide range of software packages at Officekey24

In addition to Microsoft Outlook 2021, you can purchase a wide range of other Microsoft software from 1A-Lizenz. For example, the comprehensive "Microsoft Office 2021 Home and Business" package combines all essential applications and delivers immediate productivity.
