A great way to start a Monday morning after a break is to not be able to check your email. I fired up Outlook, and got the error “Cannot start Microsoft Outlook. Cannot open the Outlook window.” (see below)
After some searching around, I came across a solution that fixed the problem.
I ran the following command in a Run box:
Outlook.exe /resetnavpane
Once I ran that command, Outlook opened with an error informing me that the data file for my mailbox wasn’t closed properly (see below). After it ran its check, Outlook opened fine.
