Alfresco + Sharepoint error?

[102020]

Ok weird one here, cause we have had this working perfectly before and keep documentation on everything.

When we hit 'edit online' via IE, get this error about missing plugin.

Now go figure, try the same process in Chrome or Firefox, and it opens exactly as expected.


Any pointers on this one? Running 4.2.f

What version of IE? I think IE11 won't work on 4.2.f.

IE11, we did have it working before, I'm thinking security setting maybe?
