.pptx file cannot be opened on phone when sent via e-mail

For some reason whenever my app automatically sends a file over e-mail, it cannot be opened/viewed on the phone. It is absolutely fine once the user opens on their desktop/outlook. But on the phone it just shows a black screen with the file title, and below it says "Office Open XML presentation" and then the file size. Any idea why? My iphone (or anyone elses) has no problem opening and viewing other pptx files.

Hi Eric,

Thank you for contacting Syncfusion support.

From the details, we suspect that you are using Microsoft PowerPoint Application to view the PPTX file on desktop. So, it opens properly on desktop. But, in IPhone you are using some other viewer which is not supported for the elements in the PPTX file and it does not open the file. And we suspect that reported issue might be due to file level information of PPTX file which you sent in email.

So, we strongly recommend you to view the PPTX file using Microsoft PowerPoint Application. If you still facing the issue after opening the PPTX file in Microsoft PowerPoint application means, could you please share the below things from your end

1. PPTX file which you sent in email
2. Viewer which you used at your end to view the PPTX file in IPhone and desktop
3. Code snippet which you used at your end to sent in email
This will be more helpful to reproduce the issue. Thereby, we will check the reported issue and will share the appropriate solution earliest.

Please let us know if you have any other questions.

Hi Hemalatha,


Thank you for getting back to me and sorry for the delayed response, having a newborn has lead to me having almost no time to work these days.


When I mentioned viewing the document, I meant just opening the file directly from the main phone mail app, not downloading it and opening somewhere else.


It took me quite some time but I finally found out the culprit, it's the INotesSlide AddNotesSlide. Without it, when sending the file via e-mail, it can be viewed normally like any other .pptx document. With it, nothing.


Below is the code:


IPresentation pptxDoc = Presentation.Create();

ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);

slide.Background.Fill.FillType = FillType.None;

INotesSlide notesSlide = slide.AddNotesSlide();

notesSlide.NotesTextBody.AddParagraph("This is it");

MemoryStream stream = new MemoryStream();

pptxDoc.Save(stream);

stream.Position = 0;

pptxDoc.Close();

pptxDoc.Dispose();

string docTitle = "PPTSample.pptx";

await JS.SaveAs(docTitle, stream.ToArray());

await stream.DisposeAsync();

stream.Close();


Any MS-PowerPoint document created by me (or anyone else) on my machine works fine on the e-mail, even with notes. Any suggestions would be appreciated. The file uploader says that the file type is not allowed.
