Office 365 Keeps Asking to Activate Account


I have Microsoft Office 360 installed on my PC and it all works fine expect I am constantly asked to activate the product after starting my PC.

The first time I open an office application after starting/restarting my PC, I am asked to activate my account.

If I am lucky it may work once or twice after starting/restarting without requesting activation but this is rare.

My user name and password are successfully recognised and I get the account update notification each time.

Also if I do not have an internet connection none of the Office applications will work, as they require on-line verification of the account.

This happened constantly on Windows 7 Ultimate and continues to happen now I have upgraded to Windows 10 Pro.

Any help would be greatly appreciated please.

Thank you,
