grommunio Web can be accessed from a modern web browser. The currently supported list of browsers of grommunio Web include, but are not limited to:

  • Google Chrome (78+), including derivatives such as Brave Browser, Ungoogled and Iridium

  • Mozilla Firefox (70+)

  • Apple Safari (12.1+)

  • Microsoft Edge (78+)

We recommend the use of a relatively recent version of the used browser. Next to security reasons, this traditionally provides the best user experience overall. While other browsers or other versions may also work, grommunio cannot guarantee their function. If you encounter any issues, we recommend to get in touch with support and open a support ticket so potential incompatibilities can be investigated.
