Windows Calendar & Outlook

Sync SilentSuite with Microsoft Outlook, Windows Calendar, or other Windows apps through the SilentSuite Bridge.

Prerequisites

1. The SilentSuite Bridge running on your PC.
2. Your SilentSuite credentials from the bridge's web UI at http://localhost:37358/.web/.

Microsoft Outlook (with CalDav Synchronizer)

Outlook does not support CalDAV natively. The free, open-source CalDav Synchronizer plugin adds full CalDAV/CardDAV support.

Install the Plugin

1. Download the latest release from GitHub.
2. Close Outlook.
3. Run the installer (.msi file).
4. Re-open Outlook. You should see a CalDav Synchronizer tab in the ribbon.

Add a Calendar Sync Profile

1. Click the CalDav Synchronizer tab in the Outlook ribbon.
2. Click Synchronization Profiles.
3. Click the + (Add) button and select Generic CalDAV/CardDAV.
4. Give the profile a name (e.g. "SilentSuite Calendar").
5. Under Server Settings, enter:
   • DAV URL: http://localhost:37358/your@email.com/
   • Username: your SilentSuite email
   • Password: your SilentSuite password
6. Click Test or discover settings. The plugin will find your calendars.
7. Select the Outlook folder to sync with (or create a new calendar folder).
8. Click OK to save.

Add a Contacts Sync Profile

1. Open Synchronization Profiles again.
2. Click + and select Generic CalDAV/CardDAV.
3. Name it (e.g. "SilentSuite Contacts").
4. Enter the same server settings as above.
5. Click Test or discover settings.
6. Select your Outlook Contacts folder as the target.
7. Click OK.

Sync

Click Synchronize now in the CalDav Synchronizer ribbon tab, or wait for the automatic sync interval (default: 30 minutes). You can adjust the interval in each profile's settings.

em Client

em Client is a Windows email, calendar, and contacts app with built-in CalDAV/CardDAV support. The free version supports up to two email accounts.

1. Open em Client and go to Menu > Accounts.
2. Click + (Add Account).
3. Select Calendar (or Contacts) > CalDAV (or CardDAV).
4. Enter:
   • Server URL: http://localhost:37358/your@email.com/
   • Username: your SilentSuite email
   • Password: your SilentSuite password
5. Click Next. em Client will discover your calendars and contacts.
6. Click Finish.

Windows Calendar & Mail App

The built-in Windows Calendar app has limited CalDAV support. It requires a workaround to add a CalDAV account.

1. Open Calendar (or Mail).
2. Go to Settings (gear icon) > Manage Accounts > Add account.
3. Select iCloud (Windows does not have a generic CalDAV option, so we use iCloud as a starting point).
4. Enter:
   • Email: your SilentSuite email
   • Password: your SilentSuite password
5. Windows will fail to connect to iCloud. When it shows the manual configuration:
   • Calendar server (CalDAV): http://localhost:37358/
   • Contacts server (CardDAV): http://localhost:37358/
6. Click Sign In.

WARNING

The Windows Calendar DAV client has known bugs with local connections. If it does not work, we recommend using Outlook with CalDav Synchronizer or em Client instead.

Running the Bridge at Startup

To run the SilentSuite Bridge automatically on Windows startup, see the DAV bridge guide for auto-start configuration.

Troubleshooting

Outlook CalDav Synchronizer not syncing

1. Open the CalDav Synchronizer tab and click Status.
2. Check for error messages in the sync log.
3. Make sure the bridge is running: open http://localhost:37358/.web/ in your browser.
4. Verify the DAV URL includes your email: http://localhost:37358/your@email.com/.

Windows Calendar won't connect

Windows 10/11 has bugs with local CalDAV connections. Try:

• Using http://127.0.0.1:37358/ instead of http://localhost:37358/.
• Switching to Outlook with CalDav Synchronizer or em Client for a more reliable experience.

Password rejected

Use your SilentSuite password (the same one you use to log into the SilentSuite web app). Verify it works by opening http://localhost:37358/.web/ in your browser.
