There are so many great training resources for Office 365 there is no excuse to not know how to get the best out of Microsoft SharePoint, OneDrive, Outlook and Teams.
The time for lazy excuses “I don’t do technology” are gone. Spending 15-30 mins a couple of times a week for a couple of weeks can improve your experience and effectiveness with these tools.
Microsoft does a great job with it’s “learn” sites. which take you through many of the advantages of 365.
We have found some of the YouTube sites from Xerillion very good, they can get a little technical but they do let you know what is possible – top tip is set the playback speed a little faster.
On this link you’ll find Microsoft video learning, it’s all based at user and isn’t to technical.
Good luck, you won’t regret the time you invest.
