Deploying Office with MAK and KMS installed

Hi,

I was wondering if deploying Outlook 2013 using a MAK key and then deploying Office 2013 using a KMS key will have any negative effects with activation? 

We are starting to see some users get a prompt that Office is not activated and it puts Office into eval mode.  Once the user reboots everything is fine but when I look at the logs I see this error;

Error: Multiple ARP entries found for product '{90150000-002A-0000-1000-0000000FF1CE}': PROPLUS Office15.OUTLOOK Type: 33::InvalidData.

Thanks,

D
