Great news! You can now add custom tiles for your Office 365 tenant.
The suitebar in Office 365 has a bunch of “tiles” added by Microsoft – tiles for all the Office apps for example.
Now you can easily add your own to that whitespace above!
You can’t force it as of now, but it’s still pretty great. Users need to add it to the app launcher themselves.
The setting is found under Admin > Company Profile > Custom tiles.
All you need to fill out is Tile name, URL, Description and Image URL.
And you’re all set! Read more about it here.
