Odd...I am assuming tht you have tried both opening via doubleclick and openeing using the File>Open menu? I have had files that refuse to open via dubleclick but will open using the menubar.

Erratic PowerPoint Mac to PC problems, too!
 

Hi,

Today I have had my share of problems. On a clients brand new Mac, we've sent a 9mb .ppt email to clients using Apple Mail. And we sent one via email - Microsoft's Mi8 outlook webaccess online client - to my client's older PC machine.

Came in fine in Mi8 web browser, downloaded, double-clicked open into powerpoint perfectly. The PC recipient that the file was sent email directly to can't open it from the mac, but can open it if I send it from the older PC.

Here's my stats:
iMac dual core, 10.4.8
PowerPoint 2004 (office, 97-2004 compatibility, append extensions checked)some image rotations listingin compatibility report, no biggies)
Apple Mail (Windows Friendly encoding, always append extensions)
Sent direct email to client using PPT 2003


Any ideas? My client, who I convinced to switch from Mac to PC is a bit miffed.

Thanks!

You convinced them to switch from Mac to PC?? I'm hoping you mean from PC to Mac.

It may be the way the email server handles MIME. On the Mac, try creating an archive (zip) of the file and sending that. Control-click on the file, then select Create Archive of "filename".
