Show all headers twice

Hi
I am using Chrome and an Outlook web version which came with my PC.

Sometime today my inbox changed to show all headers twice, I think that is what it is
referred to.

See the uploaded picture



I would appreciate any help and advice.

Regards

Daniel

You may try this:

Click on Filter > Sort by.
An arrow (in the green circle) shows which column controls the sort.
Left click on Received to change the sort.
Clicking the column heading a second time will change whether the sort is ascending or descending.

Spot on. thanks for your help.

Cheers

Daniel
