A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Since both devices use the correct account and PowerPoint is updated, please check whether the presentation has additional access restrictions:
- Open the presentation and select File > Info > Protect Presentation > Restrict Access.
- If restricted access is enabled, confirm that the recipient is included with the required permission.
- If the recipient is outside your organization, ask them to check their Junk/Spam folder for a sharing invitation or one-time verification code.
If it still does not appear, could you clarify whether the recipient receives no invitation at all or receives an error when opening it? The exact behavior will help narrow down whether this is an invitation-delivery or access-restriction issue.
I hope this helps you identify what is preventing the presentation from appearing. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
