Latest AAD Connect Removes On-Premises Disabled User Accounts from Azure AD

[Tony Redmond]

Microsoft pushed out version 2.0.88.0 of the AAD Connect synchronization utility earlier this month. Unfortunately, the new software removes disabled on-premises user accounts from Azure AD, which means that on-premises shared mailboxes disappear for cloud users. Microsoft has released version 2.0.89.0 but maybe it’s better to go back to a version that you know works. At least until after the holidays.

Disabled accounts are synchronized as well to Azure AD. Disabled accounts are common to represent resources in Exchange, for example conference rooms. The exception is users with a linked mailbox; as previously mentioned, these will never provision an account to Azure AD.
