You're running tracannouncer 1.0.dev0 with Trac 1.2. Try to see if there's a version 1.2 for the ​TH:AnnouncerPlugin (trunk seems fine, see ​TH:r16129).

Replying to Christian Boos:

I worded that commit message poorly (not the first time someone has interpreted that as "trunk supports 1.2 now"). The trunk will support 1.2, but more changes are needed.

You may not need AnnouncerPlugin with Trac 1.2 because several of the features were added to Trac.

Ok, thanks for the information. Acutally I was looking for a solution when html notifications display properly in Outlook (not the case for the current html notifications from htmlnotificationplugin). Yes, I know that this is Outlook limitation as it is not able to render certain html elements. But all other content that I receive looks fine so there must some workaround.

Regards.

For ​TracHtmlNotificationPlugin, the Genshi template is named htmlnotification_ticket.html: ​browser:trachtmlnotificationplugin/0.12/trachtmlnotification/templates/htmlnotification_ticket.html. If you create a modified version of the template you can place it in your environment or shared templates directory and it will be used by the plugin. See TracInterfaceCustomization#ProjectTemplates for more info.
