You receive an "If you are planning on sending this presentation back to the original author, you may want your changes to be marked as revisions" message when you save a PowerPoint presentation that you receive as an attachment (905166)

SYMPTOMS

Consider the following scenario. You receive a Microsoft Office PowerPoint 2003 or Microsoft PowerPoint 2002 presentation as an attachment in an e-mail message. Then, you save the presentation. In this scenario, you receive the following message:If you are planning on sending this presentation back to the original author, you may want your changes to be marked as revisions. Revision marks indicating your edits will appear when the author merges this copy with his or her original presentation. Do you want to automatically add this additional information when you save the file?

CAUSE

This behavior occurs if the presentation is in Ad-hoc review mode. PowerPoint automatically sends the presentation in Ad-hoc review mode if the original author uses the following method to send the presentation:

The author opens the PowerPoint presentation.
On the File menu, the author points to Send to and then clicks Mail recipient (as attachment).

If the original author clicks Mail recipient (for review) instead of Mail recipient (as attachment), a revisions baseline is created in the presentation file. However, a revisions baseline is not created when the presentation is in Ad-hoc review mode. You receive the message that is mentioned in the "Symptoms" section so that you can create a revisions baseline for the presentation before you send it back to the original author.

WORKAROUND

To work around this behavior, create a revisions baseline when you review the presentation. To do this, follow these steps:

Open the PowerPoint presentation.
On the Tools menu, point to Macro, and then click Macros.
In the Macro name box, type AddBaseLine, and then click Create.
Type the following code in the AddBaseLine box:
```
Dim docProp As DocumentProperty

' is there already a baseline?
If ActivePresentation.HasRevisionInfo = ppRevisionInfoNone Then
' NO - then do we have the custom document properties...
For Each docProp In ActivePresentation.CustomDocumentProperties
If docProp.Name = "_AdHocReviewCycleID" Then
' we have an AdHoc presentation review...
' So add a baseline to prevent the dialog...
ActivePresentation.AddBaseLine
End If
Next
End If
```

Save the presentation.

Note To use this workaround, you must clear the Add properties to attachments to enable Reply with Changes check box in Microsoft Office Outlook 2003 and in Microsoft Outlook 2002. To do this, follow these steps:

Start Outlook 2003 or Outlook 2002.
On the Tools menu, click Options.
Click the Preferences tab, and then click E-mail Options.
Click Advanced E-mail Options, click to clear the Add properties to attachments to enable Reply with Changes check box, and then click OK three times.

MORE INFORMATION

The Ad-hoc review mode is determined by the following set of custom document properties that are added to the presentation:

AdHocReviewCycleID
EmailSubject
AuthorEmail
AuthorEmailDisplayName
ReviewingToolsShownOnce

When you open the presentation, PowerPoint reads these properties to determine whether the presentation must be in Ad-hoc review mode. Even if you delete these properties when you review this presentation, you will still receive the message that is mentioned in the "Symptoms" section when you save the document.
