One of the benefits of being a “Microsoft Cloud Accelerate” partner is the ability to offer delegated administration right from within your own Office 365 tenant. Delegated administration is you administrering a company account on behalf of one (or more) of your customers. As a delegated administrator, you can perform simple tasks such as adding users and resetting passwords, or more technical tasks such as adding a domain.
Two questions often comes up when delegated administration is on the agenda:
How to invite your customer to authorize you as a delegated administrator
Before you can start administering your customer's account, your customer must authorize you as a delegated administrator. To obtain your customers approval, you first send them an offer for delegated administration:
How to actually do the delegated administration
When you want to perform an administrative task for your customer, you can locate the account by searching for a user (name) or your customers domain name. If you are a delegated administrator for your customer's account, you can search for any domain name associated with the account.
Thats it :-)
Note: As a Microsoft partner, you can see a list of your Office 365 customers on your MPN Partner Dashboard: https://partnerdashboard.microsoft.com/PartnerDashBoard/home.mvc/show/PartnerId=[MPN ID]#/#onlineServicesTab
Great thanks for posting this It would have taken me a while to figure it out as it not verry straight forward. If you already authorized to deligate then the domain should just show up to click on.
too bad they pulled away features in the latest service upgrade, for example you can no longer administer distribution lists without a "licensed" user account.
