Flow Add-in For Excel

Hi all,

I have been attempting to use the Flow Add-In for Excel (Preview).  The problem I am having is when I open the Flow Preview, nothing really happens.  It appears that,  for a while, Excel attempts to load the Flow add-in, but eventually fails (leaving a blank preview window).  If I right click in the window and try to reload, I get the same result.  I have already tried to Repair my Office install via the control panel.  Not sure what else to do.  Anyone else have this problem? Suggestions for a fix?

Re: Flow Add-in For Excel

Hi @james_g,


I have made a test on my side and don't have the issue that you mentioned.


Could you please reproduce the steps?

Or could you please share some screenshots of the steps and the issue?


Please share more details so we would try to provide a proper workaround for you.


Best regards,

Hi @v-yuazh-msft 

I hope it's okay that I just add a bug to this thread ...
Do you know why can't I log in to the Flow Add In for Excel with my Office 365 subscription?


Error Message; (partially censored)

"User account '' from identity provider '' does not exist in tenant 'Microsoft' and cannot access the application '......................'(Microsoft Flow Launch Panel) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account."
