KBase enables Outlook users to create knowledge base articles with standard Outlook tools for text formatting, spell checking, images, and attachments. Articles can be shared using Access, SQL Server database, or SharePoint site.

One of the most significant advantages of KBase is that the articles you create can be shared in the workgroup via an Access or SQL Server database or through a SharePoint site. Besides, you can easily categorize your articles and do a full-text search to find what you need easily.
With KBase, you'll have access to a wide range of features. For instance, the software allows you to have the knowledge base available right inside Outlook, an environment that users already know. You can use all Outlook features, including rich text, HTML, and attached files, to create your articles. Additionally, your articles will have a reading pane and spell checking.
Another powerful feature of KBase is its ability to allow drop-downs in the articles for selecting article categories and types. You can quickly define the categories and types to select in the tree view in the KBase settings. Even better, the software lets you create custom fields easily without any coding. All you need to do is to write a name for it in the KBase settings, and it will be created automatically.
Suppose you need to save articles as .htm files or export them to Excel. In that case, KBase has got you covered. Lastly, KBase comes with a fully-featured download, only constrained by a nag screen. If you're looking for software that makes sharing and categorizing your knowledge base much more manageable while ensuring your Outlook environment is still familiar to use, then KBase is worth checking out.
