What's the most efecitve way to immediately disable an account on office 365?
Let me give you an example. One of our customers dismissed one of their employees recently. They required that this user lost access to their emails as soon as they left the building, otherwise there is the possibility of using the company emails maliciously. My actions were to change the 'settings' section in the user's 365 settings (through the management console) to blocked; convert the mailbox to a shared mailbox (the mails were still required by other employees) and the remove the 365 licence from the user..... I was informed by the client that the dismissed user was still sending & receiving emails from their phone about 2 hours after this.
I then deleted the user's account in the management console, only to find that the shared mailbox also disappeared! To return this, I am having to restore the user account, but by doing this I will no doubt restore the dismissed user's access!
We have had a similar experiance in the past where we simply changed the password on the account.... The customer informed us the user was still sending/receiving emails from their phone up to 8 hours after this, only then were they asked for the new password.
There must be a way to immediately revoke access to the office 365 environment, I was wondering if any of you guys have the right way to do this. Tearing my hair out at the moment..... Bring back exchange servers, all is forgiven!
