Configuring preferences and options in Outlook on the web for business
I thought selecting "show" pane would solve it, but it didn't. Did not find this answer anywhere.
** Here's the deal. I finally figured it out. Under the HOME tab, there is a button "Toggle Left Pane" - click on it and the folder pane will stay open.
Hope this helps.
I do not see any button saying "Toggle Left Pane" on the Home tab!
Searched for that exact thing in the help button - no finds for the search.
You have some magic form of Outlook.....
