General 

Microsoft recommends the following minimum general hardware requirements to run Outlook on the Web. These requirements therefore also apply to running the Cryptshare for OWA Add-in.

We strongly suggest exceeding these requirements, as the Outlook web app may be demanding at times. Older devices may be served the "light version" of Outlook, which does not support add-ins.

Official Microsoft recommended requirements, as of September 2023:

• Processor: 1.6 GHz or higher, or Intel-based Mac computer
• Memory: 1 GB of RAM or higher
• Resolution: 1024 × 768 minimum
• Internet connection: High-speed internet access is recommended.

Operating System

These requirements match the Microsoft recommendations. It is advised to generally use the latest operating system version available.

• Windows 7 or later
• Mac OS X 10.10 or later
• Linux: Known to work in Firefox and Chrome. Some features may not be available.

Web Browsers

Browser	Minimum supported version
Chrome	Newest version on Windows and on other platforms
Microsoft Edge	Newest version on Win & Mac

Unsupported Browsers

• Firefox is not supported at the moment.
• OWA only works in Safarai with 3rd Party Cookies enabled, which is not something we recommend to do, therefore we currently don't officially support Safari
• In line with Microsoft browser support, other browsers such as Internet Explorer 11 & Edge Legacy and all mobile browsers are not supported.

Cryptshare Server Environment

For more details about setting up the Cryptshare Server environment, refer to Server Environment.

Exchange Online / Outlook Environment

In order to be able to use the Cryptshare for OWA add-in, an active Microsoft 365 (formerly Office 365) subscription including Exchange Online and the ability to sideload add-ins is required.

Cryptshare for OWA was created for Outlook on the Web. Most features should work with little to no restrictions in the Outlook for Windows Desktop Client.
