Hi, There,

CXNShared addin is not available in PowerPoint.  But it is available for all other Office applications, Word, Excel and outlook.  Here are error message from PowerPoint and Windows Event.  Could you please take a look?  Thanks.

Hi Zhaowen,


can we meet regarding this issue on a screen share meeting, my assumption is that we need to reenable the addin. I would like to take a closer look on that.

Please let me know the timeframe that would be appropriate for you.
