My operating system is Windows 10. I use Outlook to create and receive emails in Office 365. I also use Nuance Dragon for voice dictation (professional version 15). Every time I go to highlight incorrectly typed words in an Outlook email and then try to correct them with a Nuance Dragon voice-over command, Outlook immediately shuts down and then restarts. When Outlook restarts I have lost the email that I was preparing and I have to start over again. This problem has only started recently. I have being using the 2 software's with no issues for months. I contacted Nuance Dragon tech support and they told me it was a compatibility issue between Office 365 and Nuance Dragon. They had actually heard about this problem from other users. They had no solution and suggested that I type all my emails in what is called the Dictation box. Once I have correctly completed the email in the dictation box, I should transfer it into Outlook and then send it. I would prefer to prepare my emails directly in Outlook as before. I am not having this problem with any other Office 365 programs like Word or Excel. Has anybody experienced this issue, and if so, are you aware of any solutions? Thanks!
