- Device & OS
- not provided
- Scenario

Frequently Asked Questions
Why does PowerPoint force me to save a read-only attachment?
This is typically caused by a known bug introduced in a specific Microsoft Office update (especially noted in Office 2016). The application incorrectly flags the read-only file as modified upon opening, triggering a 'Save As' prompt when you try to close it.
Does this save prompt issue affect Microsoft Word or Excel?
Usually, no. In most reported cases, this specific bug is isolated to Microsoft PowerPoint. Attachments opened in Word and Excel from Outlook can be closed normally without a forced save prompt.
Can I disable the save prompt in PowerPoint's settings?
No, there is no setting to disable this specific prompt because it is caused by a software bug rather than an intended configuration. The only permanent fix is to update your Microsoft Office suite to a patched version.
