Outlook 2016 errors while reading emails with tables

[Neurrone]

Steps to reproduce:

1. Read a moderately complex email that contains tables such as linked in's invites. I'm not sure what the best way would be to post a sample email that can be imported into outlook.
2. Do a say all. It stops reading once it encounters this error:

ERROR - queueHandler.pumpAll (12:50:10.961):
error in generator 325
Traceback (most recent call last):
  File "queueHandler.pyc", line 72, in pumpAll

COMError: (-2146822463, None, (u'Object has been deleted.', u'Microsoft Word', u'wdmain11.chm', 25305, None))

3. The same error appears as well when moving using the arrow keys, just with a slightly different call stack.

Expected behavior:

The email should read normally without stopping on errors.

Actual behavior:

It stops reading in say all when encountering this error. When using arrow navigation, it errors when encountering the triggering line, and is unable to read it.

System configuration:

NVDA version:
master-14204,86f50927

NVDA Installed or portable:
Installed

Windows version:
Windows 10 version 1611

Name and version of other software in use when reproducing the issue:
Outlook 2016

Other questions:

Does the issue still occur after restarting your PC?
Yes

Have you tried any other versions of NVDA?
Not yet, but this only started happening recently, (like a month ago?) so its either an outlook or NVDA change.

Bump, seeing a lot of these recently.
