If you want to use some of the advanced features of SharePoint Online or Exchange Online - it's important that you have the right organization hierarchy set up. This isn't applicable to a 3-10 person business - but to the upper end of SMBs, this is very applicable....especially if you want to use some of our custom workflows for Exchange Online.
To set up your organizational hierarchy in Office 365 - log in as the administrator for your Office 365 account and then choose 'Manage' for Exchange Online.
Then highlight the person's name that you want to manage and choose details.
Navigate down to Organization and then browse out to their manager.
