Exchange Compatibility
TaskTask is compatible with all Microsoft Exchange Server 2003 and newer servers, given the following configuration requirements. TaskTask is compatible with default Exchange configurations for these versions, but some IT administrators may take extra steps to lock down their Exchange mail configurations.
If you use an RSA SecurID, Smart Card, or other two-factor authentication system to access Outlook Web Access, TaskTask will not work for you.
TaskTask will not work with Google Apps / Gmail, Zimbra, or other non-Microsoft Exchange implementations. TaskTask does not use Exchange ActiveSync due to license restrictions, but rather uses WebDAV or Exchange Web Services.
Determining Your Exchange Server Version
To determine the version of Exchange your mailbox is running on:
- Log into Outlook Web Access using your web browser.
- Select the Options button or link (depending your version of Exchange)
- Click on About
- Look for “Microsoft Exchange Client Access server version” and compare the version number to these supported values:
- Exchange Server 2003 SP1 will be version 6.5.7226 or higher
- Exchange Server 2007 is 8.0.685.24 or higher
- Exchange Server 2010 is 14.00.0639.021 or higher
If you have a version of Exchange that is lower than 6.5.7226, TaskTask will not be compatible with your server.
Server Configuration Requirements
For Exchange 2003 Servers:
- WebDAV support is enabled on the server and through any firewall
- WebDAV verbs: GET, POST, PROPPATCH, SEARCH, PROPFIND, BPROPFIND, BMOVE, HEAD
- Authentication: Basic (plain text), Windows Integrated Authentication (NTLM), or standard forms-based authentication (no custom properties or two-factor authentication).
Some firewall configurations block the WebDAV commands used by TaskTask, so even if you can access Outlook Web Access you may not be able to use TaskTask. Contact your Exchange administrator to make sure your server is not blocking these commands.
For Exchange 2007 and Exchange 2010 Servers:
- For automatic account configuration, autodiscover published using the DNS naming scheme (autodiscover.yourdomain.com)
- Exchange Web Services enabled and published (if not using autodiscover, it must be published in the default virtual directory, /ews)
- Authentication: Basic (plain text) or Windows Integrated Authentication (NTLM)
- With Exchange 2010: Some servers are configured to only support “Negotiate” auth. TaskTask is not compatible with this setting and requires either Basic or NTLM authentication to be specifically enabled. TaskTask 3.0 and later show an error message indicating this condition.
