Linking NextCloud / OwnCloud with Hosted Zimbra

You can link your NextCloud or OwnCloud environment to your Hosted Zimbra environment to share your files with a link or as an attachment in an email or attachments from an email directly to your NextCloud or OwnCloud environment.

To establish the link, you need to create a so-called OAuth 2.0 account and provide those details to us. We then use that data to establish a link from Hosted Zimbra to your NextCloud or OwnCloud environment.

the steps for NextCloud

Provide access details to Hosting.NL’s customer service department
