Environment

Microsoft Office 365 Adobe Sign add-in

Question

How can I install the Adobe Sign Microsoft Word/Office 365 add-ins with no loading errors?

Answer

Try the following steps:-

  1. Log out from Word 2016 /PowerPoint 2016.
  2. Install Adobe Sign add-in or any other add-in.
  3. Log in Word 2016 with Adobe account.
  4. You are able to use the add-in without any problems.

If an error still persists, try the following instead:

For Windows:
Delete the content of the folder %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\
Also clear the …\16.0\WebServiceCache

For Mac:
Delete the content of the folder /Users/{your_name_on_the_device}/Library/Containers/com.Microsoft.OsfWebHost/Data/

Start word and add the add-in if not prompted already.
You are asked to trust the add-in again.
