guest user admin

[Taen keren]

Hi 

I was once thought by and MVP that the "right way" to get into a clients Azure Portal was to create/invite my own mail as a guest user and then afterwards assign the proper Directory roles (global admin, exchange admin etc.)

However - I get into the (clients) Azure portal just fine and can do anything in there (and can switch directories) - but when I try to go to the O365 admin portal or the EXO admin - I get my own "Tenant" and can't switch to the clients tenant.

Are this the "right" way or do I need a <client>.onmicrosoft.com global admin -
if not - how do I "switch" to the client admin o365/EXO ecp admin center?

Hope it makes sense - otherwise I can elaborate :)

Sorry to pull this one out of the grave, but I came across this by chance, and thought I would just fill out the answer for anyone else passing by :)

The thing is that a guest identity is not really the best way to access these other portals - MS is working on it, but this work is mostly relevant for Partners that have adopted the partner identity eco system.

IF you are "just" helping out a few clients and have never bothered to setup your MS partner account for management of clients, then you would be best off by creating a dedicated user in the clients tenant.
There is nothing "wrong" in doing this, but you might not enjoy having to manage too many separate identities though.

Hope this helps.
