How to Use a VPN with Outlook and Office 365

Office 365 offers incredible utility for professional and everday applications alike, but it still has some security flaws. Before you panic that someone might hack into your Outlook inbox, consider how easy it is to get set up with a VPN to enhance your privacy online. We walk you through the process in our VPN quick-start guide for Office 365 users below.

Office 365 was first released in 2011 as a part of the Microsoft Office group of products. The biggest benefit of using Office 365 is being able to access applications like Outlook without experiencing firewall blocks. In addition, Office 365 works with a cloud service, so you can access your data remotely without being tied down to your office space or home. While this solution brings with it a plethora of benefits, there are still concerns over security risks that come with using cloud services at scale. Enter virtual private networks to shore up the gap.

Upgrade your privacy when using Office 365 and Outlook with these VPNs:

  1. NordVPNBest for Outlook – With powerful encryption, a vast server network, great speeds and reliable network stability, NordVPN is a productive, secure companion for Office 365.
  2. Surfshark – Unlimited simultaneous connections, split tunneling, and advanced VPN protocols.
  3. ExpressVPN – Blazing fast network speeds and a great logging policy.
  4. CyberGhost – Well-trusted generalist VPN with some specialist tricks up its sleeve.
  5. PrivateVPN – Owns their entire server network, offering total privacy online.
  6. PureVPN – A complete cybersecurity suite including powerful VPN provisions.

However, it’s not enough to just get any old VPN. You need a quality provider to ensure optimal protection, reliability, and ease of use. In this article, we’ll discuss how to pick the right VPN service, offer you our favorite provider recommendations, and delve into benefits of using a VPN.

Why use a VPN for Office 365 and Outlook?


Using Office 365, as well as Outlook, comes with many advantages. However, there has been some debate over how safe the cloud is for storing sensitive information. Rather than trusting Microsoft with the data of your entire business (or even personal), choosing a VPN provider will protect all your information at a small price. Whether you are a journalist covering a sensitive topic or an employee doing market research, a VPN with military-grade encryption and a no-logging policy will ensure that no one, from cybercriminals to your ISP, will be able to access your data. It does so by manipulating your IP address and rendering you untraceable.

Accessing the cloud from abroad

A VPN can be a life saver if you are located abroad and need to access your personal files on Office 365. Not only will it become a bulletproof way to work remotely while traveling, but you will be able to access all your personal accounts wherever you are located in the world. Many users have reported connectivity issues or even connection loss when accessing Office 365 applications with an active VPN. However, with one of our recommended providers, you will have no such issue. In addition, you’ll be able to get access to your personal accounts, such as your bank account, while bypassing regional blocks and keeping your data secure when you’re not using Microsoft Office products.

Bypassing censorship blocks

One of the major advantages of using a VPN service is sidestepping geoblocks and firewall restrictions. If you are travelling for work but your work files are restricted under your company’s firewall, a VPN is there to solve all your problems. Additionally, a VPN service will allow you to access massive ranges of Netflix content, as well as other restricted pages or services from abroad. For example, if you are looking to access Wikipedia or Facebook from China, using a VPN will allow you to do so without running into restrictions placed by the Great Firewall of China.

Using Office and Outlook from a public or hotel WiFi

If you are abroad for work and are about to access all your personal files on Office 365 through the hotel or public WiFi, please think twice. You may be unaware of this, but public hotspots are not safe for confidential browsing or emailing on Outlook. This is because there is no encryption on data passing through these servers, and even an untrained hacker will be able to intercept this sort of connection with a simple plugin. In order to keep your personal and professional data private, you will need an encrypted connection, which is something you can get with a quality VPN. Not only will it make you anonymous online, but your files will be inaccessible to malicious hackers and cybercriminals.

How to choose a great VPN

Using a VPN to protect your connection while using Outlook and Office 365 is typically a breeze, but finding the right provider can prove to be a challenge. After all, the VPN market is a crowded one, and many companies claim to be the best, for better or worse. We narrowed down the field using the following search criteria:

  • Strong encryption – You need a VPN service that uses strong encryption like 256-bit AES. This level of data encryption will protect your data and identity from getting into the hands of the government, ISPs, and even hackers.
  • No-logging policy – A comprehensive no-logging policy will ensure that none of your data or personal information is stored in your ISP’s or VPN provider’s system for interested third parties to find. This policy should cover as much data as possible, including browsing history, IP addresses, and timestamps.
  • Server network – the bigger the server network, the more connections you will have in terms of international IPs. This feature will allow you to bypass geoblocks and establish a fast connection. Moreover, larger networks are usually faster.
  • Speed and performance – Choose a provider that doesn’t limit bandwidth, use speed caps, or throttle the connection. What’s more, your provider’s encryption methods should be refined enough to preserve as much of your natural connection speed as possible.
  • Device compatibility – You want your VPN to be compatible with as many devices and operating systems as possible. After all, even the greatest VPN in the world is useless to you if you can’t use it with your device in some way.

Most secure VPN recommendations for Outlook and Office 365

Looking for a the perfect VPN for your Office 365-equipped device? Take a look at our top 6 recommended providers:

1. NordVPN

NordVPN - Editors choice

NordVPN is another one of our top recommendations due to its advanced features and massive server network. The provider has 5,500+ servers in 58 countries, which makes it the largest network in the entire industry. The location distribution allows you to connect virtually to any location excluding Antarctica, meaning you’ll be able to overcome geoblocks and establish the fastest available connection no matter where you’re using Office. Another important feature is the large number of specialty servers. For example, Obfuscated Servers hide the fact that you are using a VPN while Double VPN servers route your data through two layers of encryption, ensuring no one outside of your circle can access your data.

In addition to the above, NordVPN employs impeccable security features. With 256-bit AES encryption keys, you can be certain that even the world’s strongest supercomputer will not be able to access your data. Furthermore, the provider’s no-logging policy, covering everything from traffic to bandwidth and browsing history, is considered to be the most complete policy in the industry. Additional features for ultimate privacy and security include an automatic kill switch and a DNS leak test, both of which help stop data leaks before they reach your ISP (albeit via different mechanisms).

2. Surfshark

Surfshark VPN

Whether you’re trying to boost the security of your home office or you need to interact with data on the cloud while traveling abroad, Surfshark is a smart choice for Office 365 users.

It boasts some of the most modern privacy provisions in the industry, including the NSA-approved 256-AES-GCM encryption cipher. Moreover, Surfshark has dumped outdated tunneling protocols in favor of faster, more secure options like OpenVPN, IKEv2/IPSec, WireGuard. Together, these create an unbreakable link between your device and the free and open Internet, free of surveillance, hacking, or censorship.

But there’s more for Outlook users to love; Surfshark’s Whitelister enables split-tunneling, so you can pick and choose which applications route their data through VPN servers, and which go on like normal. Outlook in particular can be finicky with certain VPN protocols, so this can be a lifesaver. You can also customize individual settings per Wi-Fi network, great for commuters on laptops.

Surfshark never keeps any logs of your identifiable metadata, and their entire 800+ server network is completely diskless and thus incapable of long-term storage.

  • Unblock 15 international Netflix libraries, including the US and Japan
  • Over 800 servers in 50 countries worldwide, and constantly growing
  • Wide app availability on desktop, mobile, consoles, smart TVs and more
  • Independently audited privacy practices
  • Responsive customer support available 24/7.
  • Server network is not nearly as expansive as major competitors
  • Young VPN still has plenty of room to grow in terms of advanced functionality.

With a server network of 3,000+ nodes in 94 countries, you have the option to establish a fast and secure connection no matter where you are in the world. In addition, ExpressVPN places no limitations on bandwidth, traffic, or server switches, making it ideal for corporate use (which can use a lot of data). Getting started is fast and easy too thanks to dedicated apps for a wide range of systems, including Windows, Mac OS, Linux, iOS, Android, and even routers like D-Link and Tomato.

ExpressVPN’s security features are highly advanced, with 256-bit AES encryption at its core. Cracking a single key would take a supercomputer millions of years, leaving little hope for hackers, ISPs, or whoever else might want your data. Specific encryption protocols include OpenVPN’s UDP and TCP, as well as SSTP, which helps beat even the most hardcore censorship blocks (think China). Additionally, ExpressVPN has a solid no-logging policy on traffic, DNS requests, and even browsing history, which will ensure that no third parties ever get their hands on your information and personal data. With a built-in kill switch and DNS leak test, you can be certain that you won’t leak data to your ISP – even if your connection drops or something else goes wrong.

You can even manually select from one of over 5,500 servers in 80 countries to dial in the optimal connection.

On the security front, CyberGhost uses 256-bit AES encryption which is considered to be unbreakable. This means that third parties won’t be able to view your data, even if they manage to get access to it. Complementing the encryption is a zero-logging policy considered to be immaculate to the point that not even your email address is stored. If you are using the service on desktop, you have additional features that will protect you from data leaks and other security mishaps. These include a connection guard, an in-built kill switch, and an online tracking blocker.

In addition to all of the above, PrivateVPN lets you connect up to 6 different devices simultaneously: enough for a small office This makes PrivateVPN ideal for corporate Office 365 and Outlook life. The best part, however, is the option to do a free remote setup to help you save time.

  1. Several years ago I tried a VPN but MS Outlook would no longer recognize my GMail. Contacted Google and their “solutions” did not work. Have things changed over the years to mitigate this?
