Getting Started
What is CalDAV?
CalDAV is an open protocol that allows you to access calendar data on a remote server. It's based on WebDAV and enables calendar clients to access, create, modify, and share calendar information across multiple devices and platforms.
Key Benefits: Cross-platform compatibility, real-time synchronization, centralized calendar management, and secure access from anywhere.
Features
Real-time Sync
Automatic synchronization across all your devices
Calendar Sharing
Share calendars with colleagues and teams
Event Reminders
Never miss important events with notifications
Secure Access
SSL/TLS encryption and authentication
Client Configuration

Step 1: Install CalDAV Synchronizer
- doc_outlook_download_synchronizer
- Run the installer and follow the installation wizard
- Restart Outlook after installation completes
- You'll see a new "CalDAV Synchronizer" tab in the Outlook ribbon
Step 2: Configure CalDAV Account
- Open Outlook and click the "CalDAV Synchronizer" tab
- Click "Synchronization Profiles"
- Click "Add new profile" button
- Select "Generic CalDAV/CardDAV" as the profile type
- Enter your account details:
- Profile name: doc_optional_name
- Outlook folder: doc_outlook_folder_desc
- DAV URL:
https://caldav.lt/caldav/[your-username]/ - Username: doc_outlook_username_desc
- Password: doc_outlook_password_desc
- Click "Test or discover settings" to verify connection
- If successful, click "OK" to save the profile
Step 3: Configure Sync Settings
- In the Synchronization Profiles window, select your new profile
- Click "Edit" to adjust settings (optional)
- Choose synchronization mode:
- Two-way: doc_outlook_sync_twoway_desc
- Outlook to Server: doc_outlook_sync_outlook_to_server_desc
- Server to Outlook: doc_outlook_sync_server_to_outlook_desc
- Set synchronization interval (e.g., every 30 minutes)
- Click "OK" to save settings
Step 4: Manual Sync & Verification
- Click the "Synchronize now" button to perform initial sync
- Wait for synchronization to complete (check the status bar)
- Open your calendar folder in Outlook to verify events are syncing
- Create a test event in Outlook and verify it appears on the server
Setup Complete!
Your Outlook calendar is now synced with CalDAV Calendar. The synchronizer will run automatically at your configured interval, keeping everything up to date.

Try these solutions:
- doc_2fa_trouble_solution1_1
- doc_2fa_trouble_solution1_2
- doc_2fa_trouble_solution1_3
- Try using a backup code instead
doc_2fa_trouble2_title
You have two options:
- Enter one of your saved backup codes to log in
- If you don't have backup codes, email support@servera.lt with your account details for assistance
doc_2fa_trouble3_title
To transfer 2FA to a new device:
- Log in to your account using your old phone's authenticator or a backup code
- Go to Profile → Security
- Disable 2FA (you'll need your password)
- Install the authenticator app on your new phone
- Re-enable 2FA and scan the new QR code with your new phone
- Save the new set of backup codes
doc_2fa_trouble4_title
doc_2fa_trouble4_intro
- Have your authenticator app ready before starting the login process
- Wait for a fresh code (one that just appeared) before entering it
- Type the code quickly or copy-paste it if your app supports it
doc_2fa_trouble5_title
You can regenerate new backup codes:
- Log in to your account (using your authenticator app)
- Go to Profile → Security
- Click "Regenerate Backup Codes"
- Enter your password to confirm
- Save the new set of 10 backup codes securely
Old backup codes will no longer work after regeneration.
Best Practices for 2FA
- Save backup codes immediately when you enable 2FA
- Store backup codes securely - use a password manager or print them and store in a safe place
- Keep your phone's time synced to automatic/network time
- Use a reliable authenticator app from a trusted provider
- Regenerate backup codes if you suspect they may be compromised
- Don't disable 2FA unless absolutely necessary
