In addition to the Redmine Outlook Add-In, we recommend installing the Redmine Shared API plugin.
It helps to adjust different API`s of Redmine and Outlook to each other.
The Redmine Shared API plugin allows you to use Redmine Custom fields.
Using custom fields allows you to add specific hour start/end time slots to your Outlook calendar by using Start/End Time custom fields.
The Redmine Shared API plugin helps to support the work of Redmine user avatars, workflows (statuses depend of trackers and other).
The Redmine Shared API plugin is developed by Ahau Software and is free for downloading and installation.
Contact your Redmine admin for the installation or contact us at support@ahausoftware.com.
