I am looking for training on using the accessibility checkers and setting up Excel, Word, PowerPoint, and Outlook for ease of use for everyone.

Yes. Microsoft provides several short, focused trainings and resources that cover using the Accessibility Checker, headings, alt text, and accessible layouts across Word, Excel, PowerPoint, and Outlook.

Recommended starting points:

1. Core “how-to” video training

• Use the “Accessibility video training” hub to see a short overview of:
  • Check Accessibility button
  • Alt Text
  • Merged cells
  • PowerPoint Live
  • And more Office accessibility tools
• From that page, use the “Making your content accessible” section to jump into app-specific videos:
  • Getting started with accessible content
  • Create accessible email messages in Outlook
  • Create accessible PowerPoint presentations
  • Create accessible Word documents
  • Create accessible workbooks in Excel

These videos demonstrate practical use of Accessibility Checker, headings/structure, and alt text in each app.

2. Step-by-step: run Accessibility Checker in each app

• Word, Excel, PowerPoint (Windows desktop)
  • Select File > Info.
  • Select Check for Issues > Check Accessibility.
  • In Inspection Results, select an issue.
  • In Additional Information, review How to Fix and apply the suggested changes.
• Word, Excel, PowerPoint (ribbon shortcut)
  • Select Review > Check Accessibility.
  • In the Accessibility pane, review Errors, Warnings, and Tips.
  • Select an issue to see why it matters and how to fix it.
• OneNote
  • Select View > Check Accessibility.
• Outlook (when composing mail)
  • On the toolbar, select Edit > Check Accessibility.
  • If the button is not visible, customize the toolbar: select See more items (…) > Customize toolbar, then drag Check Accessibility onto the toolbar.

3. Word-specific guidance (headings, tables, alt text)

• Use Review > Check Accessibility to scan the document.
• In the Accessibility Checker pane, review Errors, Warnings, and Tips and fix items directly from the pane.
• For more structured guidance on accessible documents (including headings and tables), use the “Create accessible Word documents” video from the Accessibility video training hub.

4. PowerPoint-specific guidance (reading order, alt text, subtitles)

• Use Check Accessibility on the ribbon to find issues.
• Improve slides using:
  • Designer to create clean layouts and auto-generate alt text; right-click images and select Edit Alt Text to refine.
  • Start Subtitles to turn on live subtitles when presenting.
• The “Create accessible PowerPoint presentations” and “Create more accessible slides” videos walk through reading order, headings, and alt text in detail.

5. Excel-specific guidance (tables, merged cells, structure)

• Use Check Accessibility to identify issues such as merged cells, missing headers, or low-contrast content.
• The “Create accessible workbooks in Excel” video shows how to:
  • Start from accessible templates
  • Use proper table structures and headers
  • Avoid problematic merged cells when possible

6. Outlook-specific guidance (accessible email)

• Use Check Accessibility while composing messages.
• The “Create accessible email messages in Outlook” video covers:
  • Using clear headings and lists
  • Adding alt text to images
  • Ensuring good color contrast and link text

7. Central guidance and templates

• Office Accessibility Center provides broader guidance on making content accessible to everyone, including:
  • Best practices for headings, tables, and alt text
  • Cross-app guidance for Word, Excel, PowerPoint, and Outlook
• Accessible templates can be downloaded and used as starting points for accessible documents, workbooks, and presentations.

Using these modules together gives both conceptual guidance (why headings, alt text, and structure matter) and concrete steps (where to click and how to fix issues) in each Office app.
