Today a client could not open his email using Outlook 365.
Looking at the task manager I saw several outlook entries. Going back to the desktop, double clicking on the Outlook icon. it trys to start and then fails to run.
Selecting each Outlook instance in the task manager process list and then clicking the End Task button on each. Then restarting Outlook, it works.
Something failed and left some processes running that disallowed Outlook from running. And clicking on the Outlook icon again did not run the program
Task Manager is a very powerful tool in every Windows computer. It can be a huge help.
Hoping you week is good,
Bill
