Rich text and images in Planner task notes

we are introducing a new rich text enabled task notes field in the Planner Microsoft Graph API. This will result in two task notes fields in our API – the new “rich text task notes field” and the existing “plain text task notes field.” When this feature launches, Planner for the Web and for Teams (Tasks app) will support rich text in task notes. Other Planner experiences in iOS, Android, SharePoint, and Power Automate will only support plain text task notes, but we plan to update these apps to support rich text at a later date.

When this feature update is deployed, all existing task notes content will be preserved in the new rich text enabled task notes field, so users will be able to continue viewing and editing notes without interruption.

We will maintain compatibility between the rich text task notes field and plain text task notes field by ensuring both fields’ contents stay in sync.

If a user edits the rich text task notes field, all content is synced to the plain text task notes field automatically. Any rich content is converted to plain text and synced to the plain text task notes field.

If a user edits the plain text task notes field via the Microsoft Graph API or via a client which only supports the plain text field, the contents in the plain text task notes field is synced to the rich text task notes field without modification. Therefore edits to the plain text task notes field will result in the removal of any pre-existing rich text, text formatting, or images in the rich text notes field.

If a user chooses to insert images in the rich text task notes field, a preview of the image will appear in the task notes field. End users should not see any interruption in their Planner experiences. They can continue using task notes as they do today but gain the ability to insert rich text and view image previews in task notes if desired (for Planner experiences which support it).
