Hi,
We connect to our SharePoint 2013 farm through TMG server. Everything works perfect with Office 2013
Since Office 2016 our users having problems when open and save documents through TMG.
For example:
When you click on a Word document on SharePoint, Word open but only in read only mode. Normally you should see a yellow information bar with a ‘Edit document’ button.
I can go to the ‘view’ tab-> ‘Edit document’ but the document stay in read only mode but I can edit the document. When I save the document, Word trying to connect to the SharePoint document library again but that fails. Instead Word open the local c:\drive.
In fiddler I see the error “Error code: 403 Forbidden. The server denied the specified uniform locator (URL)” when Word trying to connect to the document library on SharePoint.
I did a little research and found that that the ‘Modern authentication’ in Office 2016 is set as standard.

When I set the “EnableADAL =0” then everything works perfect but that is not an option because we don't have control on all the clients with Office 2016 installed.
My question: Is there a workarounf or hotfix for TMG.
Regards,
Johan
