I have problems using the "edit in Microsoft Office" functionality of an Alfresco Enterprise 5.2.6. I use both firefox (70.0) or chrome (78) on a Windows 10 Machine (winver 1903) and I have Microsoft Office 365 Business (version 1910) activated on my machine.
When I click on the share action the office app (Word or Excel) opens but then it says it can't download the content.
The same problem is on my production server, where is also installed an ssl certificate and a nginx reverse proxy.
What do I miss? Do I need the alfresco office service amp file? Do I need a particular alfresco-global.properties configuration?
It is not a real "general" answer, but in my case it was an Nginx configuration problem. The reverse proxy did block the public url to be exposed.
