Hi Nigel,
I regret for the inconvenience.
This might have caused if Microsoft office is put to sleep in AVG TuneUp.
To wake up the program, click on the link below and refer 'Prevent applications from running in the background' and 'Undo actions performed by AVG TuneUp'.

I installed Tuneup and now Microsoft Office 365 apps won't launch. Anyone else had this?
