What's the best way to sign documents from a civilian laptop, trapped in the new mil mail system?

ARNet portal remote through citrix on a civ laptop and CAC reader, then just use Outlook (if the ARNet Portal is still available https://aramp.usar.army.mil .)

And it looks like you should be able to download and upload documents on teams with a civ windows machine, just worked when I tried it. That does not work on linux.
Truth be told, when we can finally sign docs in Teams, that will save tens of thousands of hours a year.

Also, if you to get GFE, (Govt Furnished Equipment, and every MDAY/TPU commander should have one) everything you want to retain for future records (all documents, all pst files of everything you sent and received on Outlook, etc), you can just burn to dvds before you give the laptop back. That's how fulltimers manage switching laptops every 2-5 years.

Recently, I was looking for a simple solution to create a digital signature. And I finally found it! This tool https://createmysignature.com/ turned out to be incredibly convenient and effective for me. As it turns out, you can now create a digital signature in just a few minutes, without having to use complicated programs or fill out a lot of forms. I'm shocked! It really simplifies some business moments, you can sign documents online, send emails and even make important deals without spending too much time and effort. I recommend it!!!

Navigating military systems can feel like a maze sometimes, right? I remember being in a similar bind when I needed to sign documents while on civilian equipment. What worked for me was finding a workaround within the system's constraints. Have you considered reaching out to your IT support or exploring alternative signing methods online? Oh, and speaking of finding solutions, stumbled upon some handy contracts at https://atpgov.com/contracts/2git/ that might offer some insights or resources.
