A Microsoft 365 license is a bundle of apps and services. To see what a user actually has, open their Licenses and apps tab in the Microsoft 365 admin center: it shows each license and every app it switches on, such as Power Apps for Office 365.
To change an item in a SharePoint list by hand, select it, choose Edit, change the values in the Item properties form and Save. It's also the quickest way to set up test data for an app that reads the list.
A SharePoint list can hold millions of items, but SharePoint blocks any single query that has to work through more than about 5,000 of them at once. An index on the column you filter by lets SharePoint jump straight to the matching items instead. It takes a minute to add, and the best time to add it is while the list is still small.
A SharePoint list is a table that lives on a SharePoint site: rows are items, and columns describe them. Creating one takes a minute. Getting its columns right takes a little more thought, because the name you give a column on day one is the name that apps and flows use for good.
A SharePoint site is where lists, libraries and pages live. When a site only needs to hold data or publish information, you don't want a Microsoft 365 group, a shared mailbox or a team created along with it. A communication site is that plain site, with nothing else attached.
Microsoft 365 only knows who reports to whom if somebody tells it. That "somebody" is the Manager field on each person's account, next to their Job title. Fill them in, and Outlook, Teams and the apps you build all know who someone's manager and direct reports are, and what their role is.
Before anyone can sign in to Microsoft 365, they need their own user account. An account on its own isn't enough, though: until it has a license, the person can't use Outlook, Teams, SharePoint or Power Apps. The Microsoft 365 admin center creates the account and assigns the license in one short wizard. You'll use it here.
Power Apps keeps numbers the way a calculator does — 123456.789 — but the people using your app expect to read 123,456.79. The Text() function converts a number or integer to text and formats it in the same step, as long as you know the one situation where it silently does nothing.
Team addresses such as support@ or sales@ are often distribution lists, and a customer should get the answer from that address — not from whichever teammate happened to pick the message up. Outlook on the web can send from the list, but the From line you need is hidden until you ask for it.
A team address like support@ is usually a distribution list — and creating the list is only half the job. Until someone has Send As permission on it, the team can receive mail at that address but cannot reply from it, and that permission lives in a different admin center from the one where you create the list.
