Instant Cloud syncing on your computer

The free mail.com Cloud sync app works like a folder on your Windows or Mac computer. Once you have installed the tool, this folder is continuously synchronized. So you can always see the files you saved to your mail.com Cloud when you are logged into your mail.com email in the web browser or mobile app. And you can select files for offline use, so they’ll be available even if you don’t have an internet connection.

How do I share photos and files with my trusted contacts?

Open the context menu by right-clicking on the folder or file you’d like to share. Click “Create share” to generate a share link. You can now copy this link and send it to any recipient(s) you like. The recipient(s) can use the share link to view and download the shared content, but they cannot upload their own content. Good to know: By default, the share link is valid for one year.

To make a folder or file available offline on your device at all times, right-click on the desired folder or file and then click “Make available offline”. A white check mark on a green background indicates that the content is now available offline until further notice.

How do I connect to my mail.com Cloud?

If no browser window opens after installation, click on the Cloud icon in the taskbar and then on “Open connection”. Now log in to the browser with your usual mail.com login credentials. The initial synchronization will start, as indicated by the synchronization arrow in your taskbar.
