Clients

Microsoft recommends the following minimum general hardware requirements to run Outlook on the web. These requirements therefore also apply to running the Cryptshare for Outlook on the web 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

Minimum supported version:

Chrome

Newest version on Windows and on other platforms.

Microsoft Edge

Newest version on Win & Mac.

Unsupported browsers:

Firefox

Firefox is not supported at the moment.

Safari

Outlook on the web only works in Safari with 3rd Party Cookies enabled, which is not something we recommend to do. Therefore we currently don’t officially support Safari.

IE 11 and more

In line with Microsoft browser support, other browsers such as Internet Explorer 11 & Edge Legacy and all other mobile browsers, are not supported.

Exchange online, Outlook environment

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

Most features should work with little to no restrictions in the Outlook for Windows Desktop Client.
