Microsoft
I am a bit confused about the messaging here..
In thehttps://blog.modernwork.academy/microsoft-training-services-is-microsoft-learnthere is a reference to Microsoft Training Services being the same as Microsoft Learn (or visa versa) - this article is based around a Tweet from MK on the SharePoint Team.
however in the post by Mandy Clark (good find btw!) , there is a link to an article on https://support.office.com/en-us/article/custom-learning-for-office-365-faq-d4457e92-be70-4f8a-baeb-b65b2fbafc69?ui=en-US&rs=en-US&ad=US , that says:
"Custom Learning for Office 365 (formerly Microsoft Training Services) is a digital, customized learning solution that helps customers transform their organizations"
The custom learning for Office 365 service sounds much more like the original Microsoft Training Services originally introduced by this article. Microsoft Learn sounds like something which is somewhat similar but totally different at the same time (i.e. it's not basic end user training )
So perhaps Microsoft Training Services has branched out into 2 separate services??
