WPA2 - 3/4 Digests recovered - Exhausted

[strike1953]

Hi,

I'm a little new to hashcat so my apologies if I have mis-understood anything.

I have ran an attack on a wpa2 capture, (single capture) using the mask of 8 uppercase characters. 
At around 75% of the way through I noticed the "Recovered" had changed to Recovered...: 3/4 Digests which I assumed was a good sign that all was good. (note: this could have been 3/4 from the start)
Eventually it completed at 100% but with a status......: exhausted and no output password.

My Questions..
Is this correct and the password wasn't 8 uppercase characters?
What about the 3/4 Digests? I'm of the understanding that this means it has cracked 3 hashes somewhere.
Have I messed the command up somewhere?
Should I have set an output file?

Command used:
Hashcat64.exe -m 2500 -a 3 capture.hccapx ?u?u?u?u?u?u?u?u

Thankyou so much in advance for any help
