Re: NVDA chasing Outlook 365

Jonathan COHN

First off, I don’t know why crashing in the above subject got changed to “chasing” but in any case, I was able to get a debug log but it tells little more to me.


Essentially when control-two is typed which should switch the main Outlook view from  what it is to the Calendar view, both NVDA and Outlook become unresponsive. It looks like NVDA pretty much just dies at the control-2 if I am reading the below portion of the log correctly.

Subject: [nvda] NVDA chasing Outlook 365




I have recreated this situation but not done any debugging.


NVDA 2018.1

Outlook 365

Windows 7 enterprise


  1. Open Outlook.
  2. Open a message and read it with numpad-+

Switch back to Inbox listing with alt-tab

Switch to calendar tab with control-2


At this point Outlook stops responding. I won’t be able to look at this further today, but besides simplifying down to not opening a message, what other actions do I need to do before submitting a ticket?


How do I turn on debug log as I know that will be useful. Are additional details about versions required?
