To demonstrate this concept, let’s use the following example: When we use the PowerShell cmdlet Set-Mailbox, and provide the “NEW E-mail address” that we want to add to specific Exchange Online recipients, PowerShell will remove any existing E-mail address and then add the NEW E-mail address.įor example, in an Office 365 environment, I experienced a significant number of times, a scenario in which the PowerShell command that adds the NEW E-mail address, delete even non-SMTP E-mail address such as SIP address and in addition the “onMicrosoft” built-in E-mail address. The rules of – “deleting existing E-mail address” are not so clear because in this scenario the operation of “deleting E-mail address” Is not created on purpose. When using, this option the NEW E-mail address “overrides” existing E-mail address (deleting existing E-mail address) and replace them with the NEW E-mail address that we provide.

The first method which I described as “replacing” existing E-mail address with a New E-mail address, can be a bit tricky. Replacing E-mail address with another E-mail address Deleting E-mail address from existing E-mail addresses “pool.”ġ.Replacing E-mail address with another E-mail address.The task of deleting the email address using PowerShell can be implemented in two ways: The two methods for removing (deleting) E-mail address using PowerShell The subject of – “removing existing E-mail address” using PowerShell can cause some confusion because there are two types of “deletion operations” that depend on the specific PowerShell command syntax that we use. In this article, we review the subject of removing (deleting) E-mail address by using PowerShell.
