In Outlook on my 925, I have just received an email with a 38kb .xlsx file and tap to download it.

5 minutes later and it still won't open. I have 5 bars of 3G in central London.

What's the issue?

Add the Email Account as an Exchange account - should be fixed then.. I had the same problem with my Gmail which I added as a Google Account. After I added it as a an Exchanged everything got faster

I had the same problem with any attachments, I was using IMAP but only had problems on the phone, not through webmail or through my Nexus 7. I removed the account from my phone, added it back in, and everything works fine now with exactly the same settings. Think there was some cache data problem on my phone or similar...
