Organization profile

Here is where you keep information about your company, including the email address of the technical contact, up to date. In small companies, it's often the case that the CEO or owner of the company assigned themselves as the technical contact when the Office 365 tenant was created, and later, they ended up flooded with error messages that clogged their inbox and should have been going to IT, anyway. You can fix that issue here:

The Organization profile page

There are other settings that affect your organization here. You can decide what the release schedule for your company will be: Will you get the new Microsoft releases of Office 365 updates as soon as they come out? Will you get them when Microsoft pushes them out to everyone? Or, will you choose a few users to bravely go where no user has gone before, so that they can break what no one has broken before, and advise everyone else accordingly?

There are settings here for managing custom themes, custom tiles, and custom help desk information, as well, and you can find out what continent your data centers are on.
