iSolutions has reviewed the two linked in learning courses below and recommend them for anyone who would like a greater understanding of SharePoint Online (SPO). This is especially useful if you're responsible for one or more sites or if you use SharePoint on a regular basis.

The first course is a basic introduction to using SharePoint, please note the following before taking the course:

1.  Mention is made of sub-sites, these are an old feature of SharePoint and are gradually being removed. Southampton users do not get the option to create sub-sites, if you feel you need one please contact iSolutions.
2. Classic sites are mentioned in this course, you cannot create a classic site yourself but if you need one please contact iSolutions who can create one on your behalf.
3. When editing your profile some fields may come from the University identity management system, you can view/edit these via www.subscribe.soton.ac.uk
4. When discussing guests and visitors the course does not make clear that non-Southampton people you add (via Outlook) have the same access as members. Visitor level access is read-only and can be applied to all members (in a Team Site) or individuals or groups (in a Communication site).

This second course is more in depth and covers some more advanced (but still relatively basic) things you can do with SharePoint and related applications. Note the following before taking this course:

1. This course refers to theming your site, we don't have a specific policy on this but would generally recommend leaving your site as the default (keep in mind accessibility regulations).
2. As mentioned above, sub-sites are not something we encourage and classic sites are only available via isolutions.
