I work from home for a large IT company. We us Skype for business to IM one on one with co-workers or as a group and to hold meetings. We do not use the video feature. For Skype meetings you log in to a link and if desired a presenter can share their PC screen, for spreadsheets and any other type of documentation. It is really very simple to use.
I was interested in video because I currently have a bad cold and I need to meet with clients who are sometimes frail, I used a mask today but it might have been more professional to have videoed into my conference room from my office, in any case by Tuesday I should be over major contagious period. Just wondering about future. This is first time in over 40 years I have been sick during tax season.
