Word 2016 - "Safe as" works once only after start

[Dolf]

Hi,

I recently installed Widows 10 and Office 2016. Since then I have the following problems:
- The "safe as" function works only once next use word hangs
(This function gives the same problems with excel and scanned pages)
- Opening word or excel attachments to a word document doesn't function. (PDF is ok)

Anybody the same problems? What is the solution?
Thanks in advance.
