Office 365 Administrator Left Company...

Just took on a new client who uses Office 365 for e-mail hosting. The old IT firm setup Office 365 for the client but never provided the administrator login credentials. The old IT firm is not playing nice and will no longer speak with the client. I have attempted to work with Office 365 support but they are not able to assist me because I am not on the account.

Does anyone know of a protocol to address such an issue?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have your customer's attorney contact the former IT company's attorneys and get the information.


Is there anyone at the customer who is on the access list?
Who is paying for the service? Have them referencing the bill/payment contact and clear things up, you would need to have an account that could would be setup as admin..

Usually the top person at the firm should be able to navigate to and upon login check the admin interface to see if they have requisite rights.
The issue might be that they had delegated rights among several users......
The lawyer to lawyer ............

You will have to resolve this with O365 support. They have protocols in place to elevate a regular user to Global Admin in such cases, but you will have to go over a verification process first. If the person on the line is giving you trouble, ask to speak with a manager and get escalated, they have a special team that deals with password resets/access lost scenarios.

Thank to you everyone who replied with your is greatly appreciated.

To make a long story short, there were no contracts in place between the client and other IT firm; it was all done via a hand shake. A lot of finger pointing went on between the client and the other IT firm, but in the end it was the IT firm that was not playing nice. I ended up going to the other IT firms office, introduced myself to the owner and invited him out for a beer. After about an hour of talking person-to-person, he released the credentials to me.

IMHO, each party had legitimate complaints. The overall resolution was being nice, calm and putting a human touch on things.

Again, thanks to all who replied.
