basically Open-Xchange acts as any other IMAP Mail Client. This means that you can configure Thunderbird (for example) as an additional eMail Client for all OX accounts that can do Webmail. For doing so you simply have to point your client to your IMAP and SMTP server using the credentials for the user that OX uses.
OX certainly supports EAS (Active Sync) for iOS devices as well as for Android and other mobile devices. This is done with an additional Plug-In which is described here:

For installation please have a look onto the installation guide in our oxpedia section of our website: oxpedia.org/wiki/index.php?title … tion_Guide
Please note that you would need a valid license and a LDB account in order to use the EAS feature of Open-Xchange. Additionally we also offer an Outlook integration.
