I spoke to Tech Support at 8.50 pm Australian time and was told that it is a known issue. As they are backed up with their support engineers they would arrange a call back time.
So apparently they are going to ring me tomorrow between 10.00 am and 12 noon.
I also have a brand new Macbook Pro purchased about six hours ago, spent the afternoon deleting and reinstalling. Tried the certificates solution but none with a blue tick over them, login works as I logged into this forum with it and also my account at
Microsoft Office 365 - so not an issue as far as I can see.
Will see what they do tomorrow I guess.
I at least only had 1 application not working when I chatted to Support. I was assured that a reinstall would work. I said to him is this a stab in the dark or is it a fix and I was assured it was a fix. So reinstalled and now I have lost all access to
office.
The next chat at least admitted it was beyond their knowledge and to ring the US help no, I said what is the Australian no.... still waiting for a reply 2 hours later.
