outlook add-in - efficy integration - save in error "couldn't connect to efficy - midas.dll missing"

Fri, 01 Dec 2023 11:11:21 +0000

Hi everyone,

One of my user came yesterday with a strange error popup from his outlook add-in efficy integration.

Whenever he's trying to use the add-in, outlook crashes because it couldn't connect to efficy server. then popup appears telling "couldn't load midas.dll"

Also outlook asking if I want to import dll missing from the server, which not working

i access efficy through the sidebar - and everything's ok from the web

what I already tried :
- reinstall efficy sidebar
- midas.dll is well stored in syswow64/system32
- registrer midas.dll
- update outlook

I have 30 users working with this efficy integration, and I haven't configure anything different on his computer.

Any help will be appreciated, Regards, -Antoine

Addin installation on Terminal Server

Tue, 28 Oct 2014 07:52:45 +0000

Does anyone have a script / other automated way to install the Efficy Addins on a Terminal Server for the users ?
( they don’t have admin rights )

Or does the IT need to install them with temporary admin rights on each session ?
