Problems with Office 2016 files

Hi

I'm having problems when trying to open downloaded Office 2016 files.
When choosing to open with Excel , i'm getting this message :
" Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space"

When trying the same file with the Installed Firefox version, the files opens without any problems.
Also if I disable the protected view for internet files ( in Excel trust center ) the files will open correctly, but that's not a solution.

I've tried with several versions ( 41, 48, 51 ) but with the same results

please advice
