[kkey838]

Hi. I have upgraded iOS on Iphone 6. But after upgrading i cannot open one very important ppt file which was emailed to me. Getting a message saying 'File access error'.

Any thoughts please?

You need to have Office Mobile apps for iOS, which contains Word, Excel and PowerPoint. Details are available at the Office News web site .
