Word cannot publish this post

Posts are an essential part of a blog. They are typically journal-like entries that contain information, ideas, and opinions. They are displayed in chronological order, starting with the most recent posts.

You can create a post on a SharePoint blog by using a Web browser, if you have permission to contribute to the Posts list. You don't need additional tools or programs to create content, add pictures, apply formatting, and insert hyperlinks. To post comments to a blog, you must have permission to contribute to the Comments list. In some cases, comments must be approved before they will appear on the site.
