Group-Office 6.4 updated

It's been a while since version 6.4 has been released. Since then this version has been patched with many new features! We're going to show you the highlights of them:

Updated Group-Office Assistant

We've made a new release for the Assistant which enables you to edit any Group-Office file directly on your computer. We relied on WebDAV in the first versions but WebDAV has been proven to be unreliable on some systems. That's why we're now using our own protocol to edit the files which will always work anywhere!

Default e-mail client

When you have the Group-Office assistant installed you can now set Group-Office as your default e-mail client on Windows, macOS and Linux:

Address book filters

We've extended the filter functionality with much more options. Some useful examples:

  • Find all upcoming birthdays
  • Find all contacts with invoices with the “Has links to..” and then select invoice.
  • Find contacts with recent comments

SMIME more secure

Group-Office now supports the Online Certificate Status Protocol (OCSP). This makes e-mail certificate validation more secure.

And many more

Apart from the highlights above there were many more smaller improvements, bug fixes and performance enhancements.
