How do I send files from Teams or Outlook?

In a Teams chat or channel, click + in the message box and pick Fileport, then click Open Fileport. Fileport opens in your browser and says where the link goes.

Send your files as usual, with your account's settings if you're logged in. As soon as the upload starts, its link goes into your message by itself, with a Download button, as long as Fileport's popup in Teams is still open, and you can send the message while the upload finishes. If you closed the popup, copy the link on Fileport's page and paste it in your message, and it shows the same way.

In Outlook, write a new email, click Apps and pick Fileport. Microsoft is still rolling out sending from apps in Outlook, so if Fileport isn't there yet, paste your Fileport link in the email and it shows with its Download button.
