I have a custom task pane that is visible in all explorer and inspector windows. Now, the new version of Outlook adds a vertical apps navigation bar in the left side, of course, you can make it not visible if you want through the advanced Outlook options, but now my issue is that the new navigation bar now is overlapping the leftmost side of the custom task pane. It looks like it is a bug from Microsoft. So how can I solve this issue? Any ideas guys?
I am having the same problem described in below link, see the screenshot in that link.
It is a known problem in Outlook, MS is aware of the issue, but there is no ETA on the fix.
I am not aware of a workaround except for padding your task pane with extra room on the left to allow for the overlap.
