External Sharing in SharePoint and OneDrive is changing: What You Need to Know

In an ongoing effort to create a more secure environment by default, Microsoft is introducing an important security update that will affect how external users access content shared through SharePoint and OneDrive.

Remote control through firewall

I don't know about you guys, but I help a lot of friends and family whenever computerproblems araise. And recently I had to help my mother-in-law get her new laptop on the wireless network I installed previously. I though it would be a simple thing, but I guess I was wrong.....

After looking around I came across this neat software from TeamViewer (teamviewer.com). It is free for non-comercial use, and worked across firewall and NAT's. All I had to do was to get her to plug into the LAN and download the software. The best part about the version I found, is that it runs without installing. You just need the .exe file somewhere on you disk.
