Outlook: free alternatives at a glance

Many users choose Outlook as their e-mail client and PIM (Personal Information Manager). As a component of the Microsoft Office suite, it is often a standard solution (in connection with the Microsoft Exchange Server) for businesses. Many freelancers and small companies cannot afford solutions intended for large businesses, but there are numerous e-mail management programs besides Outlook that are available for free.

A big plus: Numerous add-ons are available. This means that the email program can be expanded for example with modules for date and task administration. However, the add-ons and extensions are always tailored to the respective version. If you want to update your version of Thunderbird, you must also update add-ons, or wait until the appropriate versions are available.

Spike also relies on modern standards when it comes to security: With a single click, any communication including attached files can be encrypted (AES-256), so that your messages are optimally protected against unauthorised access. Recipients who do not use the app can also decrypt the received messages with a single click. Unlike Outlook, Spike is free for private users - monthly fees are charged for integrating business email accounts.

The program supports all major basic services, including Gmail, Exchange, iCloud, and Outlook. The list of supported email technologies also includes POP3, SMTP, IMAP, EWS, and AirSync. Some additional features such as the translation function and the extremely fast full test search function make everyday work easier. Secure communication is ensured via SSL/TLS standards, encryption is via S/MIME.

Don't be fooled by Pegasus’ simple and rather unspectacular design. The program is not only very clear and easy to use, it also offers some practical additional functions, such as a sophisticated, programmable filter function. The mail service offers a mass mail function that can not only be used by private users, but also for marketing purposes.

As the last alternative to Outlook, we present the product MICROSOFT® EXCHANGE Hosting BY 1&1 IONOS. Microsoft® Exchange Server is a groupware system that enables access to contacts, appointments, and e-mail databases within a company from anywhere in the world. In short, you can open Microsoft Office anywhere you want.

The Exchange server can also be obtained directly from Microsoft®. However, the hosted exchange solution from 1&1 IONOS is considerably beneficial to a company’s IT department. It saves the cost of purchasing a sophisticated IT infrastructure. MICROSOFT® EXCHANGE Hosting BY 1&1 IONOS provides the required server infrastructure from 1&1 IONOS.

What the 1&1 IONOS offer also includes is an all-round carefree package: In addition to the Outlook software as a desktop version and the management of mailboxes via Microsoft Exchange, you also receive your own e-mail domain.

The most important facts at a glance:

• Management of inboxes via Microsoft Exchange
• Microsoft Outlook software
• Real-time synchronisation
• Mobile access to all data
• 25 GB mailbox storage for each employee

The Microsoft Exchange package minimises the acquisition costs for a server structure and offers even more advantages: The administration effort is reduced because the provider takes care of mailbox maintenance, updating virus scanners and spam filters and continuously running software updates. All data is hosted on security servers with a specially secured infrastructure. If you are looking for a professional e-mail client solution, the 1&1 IONOS variant is a good Outlook alternative - even if it is not available free of charge per se.

The offer may be too extensive for private users, but it is a good option for freelancers and entrepreneurs and especially for small and medium-sized companies. If you understand the importance of a professional appearance and high security standards, then you’ll benefit from an ideal price-performance ratio.

Outlook is not usually the first choice for mobile internet users. Depending on the operating system, smartphones and other mobile devices come equipped with e-mail programs, calendars, and contact management functions. The pre-installed apps are a good solution for private users and Google apps are especially popular on Android devices. The same also applies to businesses, which increasingly consider Google products as the go-to choice. Synchronising different apps, calendars, e-mails, and contacts is not complicated and Apple users can use pre-installed products and dock these onto an Exchange account or a Google app.
