We recently upgraded an on premise customer to Efficy 11.1
After the upgrade the customer has a problem with opening DOCX files from Efficy documents.
Directly after opening the "connection" between the Efficy-document and the file is lost: When the user saves the file, an error pops up: "There was an error uploading the file, do you want to try again ?"
What is special:
This problem only occurs on DOCX and XLSX files. DOC files and XLS files and any other types of files (rtf, txt) works fine.
The problem only occurs on devices of the customer. I cannot reproduce the problem on my own machine.
The customer works on Office 365 ProPlus
