How can I tell whether OpenProtocols will work with my Messaging Service Provider?
This largely depends on whether your service provider provides CalDAV/CardDAV and what services they provide. You should contact your service provider to determine the servername and port of their CalDAV/CardDAV services.
A list of service providers is available here.
How do I trial the connector?
The first step is to download the connector and install it on your Windows Outlook Computer. For testing the connector against your service provider, it is suggested that you create a new Outlook Profile (you can add it to your existing profile once you have validated it against your service provider).
You can then configure OpenProtocols as a message service under the profile. The connector will prompt you for your email address and password and will then attempt to determine your settings from your service provider (via DNS lookup and Autodiscovery).
You should enable the advanced settings dialog and confirm the DAV settings (or configure an alternate DAV provider if you wish to use a service like Fruux).
Can I use the connector if my Messaging Service Provider does not provide CalDAV or CardDAV?
Yes, you can still use the connector, but your contacts and calendar items will not be published to your service provider.
You can also use a separate service provider like (Fruux) or indeed anyone who provides DAV services, to publish your calendar.
For example, you can connect to your Outlook.com account via IMAP, and use Apple/iCloud, Fruux, OwnCloud, etc. to store your Contacts and Calendar.
Can I use OpenProtocols against Yahoo! ?
Yes, if you configure OpenProtocols to connect to Yahoo!, you will be able to access your Yahoo Mail, Calendar, Contacts, Contact Groups and Notes.
Currently, Yahoo does not appear to provide Tasks, Free-Busy or a Global/Shared address list.
Can I use OpenProtocols against Apple/iCloud?
Yes, if you configure OpenProtocols to connect to iCloud; you will be able to access iCloud Mail, Calendar, Contacts, Notes, Tasks, Groups and Free/Busy information.
Currently, iCloud does not appear to provide a Global/Shared address list, so this option will not be available within your Outlook Profile.
In order to be able to access iCloud with the connector, you must have two-factor authentication enabled on your Apple account and generate an app-specific password (please see
You should use the following values in the account settings:
IMAP Server: imap.mail.me.com Port Number: 443 Use SSL: Yes
CalDAV Server: https://caldav.icloud.com Port Number: 443 Use SSL: Yes
CardDAV Server: https://contacts.icloud.com Port Number: 443 Use SSL: Yes
How do I use OpenProtocols with Fruux?
Fruux is a service that allows synchronisation of Contacts, Tasks, Calendars across devices. It provides a CalDAV and CardDAV interfaces.
Because OpenProtocols allows you to specify separate mail and DAV server settings, you can configure it to publish/integrate Contacts/Calendar/Task items with Fruux.
How do I use OpenProtocols with Synology?
OpenProtocols will work with Synology, although current releases of Synology's CalDAV/CardDAV implementations have some service/resource discovery limitations. Specifically, they do not support bootstrapping / well-known URLs).
As such, it is necessary to provide the client with more information as to the specific location of calendar/address book resources.
The Synology control panel it will give you an indication as to the location of you CalDAV and CardDAV resources, however if you know the port and user/credentials, typical settings for OpenProtocols/DAV follow:
In order to configure Contacts and Calendar with OwnCloud, you will need to know the server name and port settings to connect to the its CalDAV/CardDAV service.
The Connector only requires the server host name/IP address and port number. (ie: there is no need to specify a fully qualified http path as the server name).
It will then use those settings to find the actual location of DAV resources.
You should use the following values in the connector's DAV settings:
CalDAV Server: [OwnCloud Server/IP Address] Port Number: [Try port 80 without SSL or 443 with SSL enabled, otherwise ask server manager] CardDAV Server: [OwnCloud Server/IP Address] Port Number: [Try port 80 No-SSL or 443 with SSL, otherwise ask server manager]
How do I enter a License Key for the Connector?
License keys can be entered under the SERVER/OPTIONS Menu/Ribbon Bar.
The SERVER menu will only appear if you have selected a folder or message store within Outlook that is configured for OpenProtocols/DAV Connectivity.
If you are unable to locate the menu item, the connector may not be installed correctly.
The solution for this is to download and install the latest version of the connector from www.arpdev.com (and see if the menu/ribbon item then appears).
If it does not appear, then you should access the File/Options/Add-Ins/Manage: COM Add-ins menu and ensure that the OpenProtocols connector is enabled.
