Zimbra

Objective

Zimbra Pro email accounts have a storage space, called Briefcase, which can be used to exchange files via the WebDAV feature. This feature is available via the Zimbra Webmail and can also be set up on your computer to display the Briefcase as a storage volume.

Find out how to mount a Zimbra WebDAV folder on your computer.

Requirements

An OVHcloud Zimbra Pro email address.
A Windows or macOS computer.
The credentials related to the email address attached to the Zimbra Pro account.

Instructions

WebDAV (Web-based Distributed Authoring and Versioning) is an extension of the HTTP protocol that allows you to manage files remotely on a server and modify them as if they were local.

The storage space allocated to your Zimbra email account is shared between your emails and the files in the Briefcase. Each file uploaded to the Zimbra Briefcase cannot exceed 100 MB.

In this documentation, we will use the example email address john.smith@mydomain.ovh and we will mount the Briefcase folder which is present by default.

Mount a folder from Windows

Before you can connect to your WebDAV folder from the Windows Explorer, you need to enable and configure the services related to connecting to a WebDAV volume.

1. Enable the WebClient service

Step 1
Step 2

Open Services from the Windows Start menu.

Identify the WebClient service in the list.
Right-click on WebClient, then click on Properties.
Switch the Startup type to Automatic.
Click on Start to start the service, then click on OK to confirm the changes.

2. Modify the WebClient registry key

Step 1
Step 2

Open the Registry Editor from the Windows Start menu.

Identify the WebClient service in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\BasicAuthLevel tree.
Double-click on the registry key BasicAuthLevel.
Change the Value data: by default set to 1, replace it with the value 2 and then click on OK to confirm the changes.

3. Import the Zimbra server SSL certificate

To export the SSL certificate, we used the Mozilla Firefox browser.

Step 2
Step 3
Step 4

Open your web browser, load the page https://zimbra1.mail.ovh.net/, then click on the padlock icon in the address bar.
Click on Secure Connection.
Click on More information.

Click on View Certificate.
From the window that appears, stay on the zimbra1.mail.ovh.net tab and click on PEM (cert) to download the SSL certificate.

Change the file extension from .pem to .cer.

Open the file zimbra1-mail-ovh-net.cer, then click on Install Certificate….
Click on Local Machine, then click on Next.
Check Place all certificates in the following store, then click on Browse….
Select the Trusted Root Certification Authorities folder, then click on OK.

4. Mount the volume

In our example, we are using the Zimbra account email address john.smith@mydomain.ovh and the Briefcase folder, created by default in the Zimbra storage space.

Open the Windows file explorer and click on This PC.
In the top bar, click on the button …, then on Map network drive.
In the window that appears, enter the folder path. According to our example, the path is \\zimbra1.mail.ovh.net@SSL\dav\john.smith@mydomain.ovh\Briefcase. Click on Finish.
An authentication window opens, enter the Username corresponding to the full email address and the Password associated with it. Click on OK.

Your network volume is now displayed. You can place your files in it, up to a limit of 100 MB per file.

Mount a folder from macOS

On macOS, it is not necessary to enable a service or register the SSL certificate, you just need to mount the volume directly from the Finder.

Step 1
Step 2
Step 3

Open the Finder.
In the top bar, click on the Go menu.
Click on Connect to Server (⌘ + K).

It is important to replace the @ in your email address with %40 in the path entry.

From the window that appears, enter the connection path suitable for your email address and the folder you want to connect. According to our example, the path is https://zimbra1.mail.ovh.net/dav/john.smith%40mydomain.ovh/Briefcase.
Click on Connect.

A server validation window for zimbra1.mail.ovh.net appears, click on Connect.
A new window will ask you to enter the Name corresponding to your full email address and the Password associated with it. Check Remember this password in my keychain if you want to keep it for a future connection to another folder. Click on Connect to mount the volume.
