Please assist me with a exch ps o365 script to remove email from all o365 mailboxes by subject line or sender email address. I cannot seem to find the right command to do in cloud.

Just to add the eDiscovery method as well, as Search-Mailbox might disappear at any time now: https://docs.microsoft.com/en-us/microsoft-365/compliance/search-for-and-delete-messages-in-your-organization?view=o365-worldwide
"By default, Search-Mailbox is available only in the Mailbox Search or Mailbox Import Export roles, and these roles aren't assigned to *any* role groups. To use this cmdlet, you need to add one or both of the roles to a role group (for example, the Organization Management role group). Only the Mailbox Import Export role gives you access to the DeleteContent parameter."

How are you connecting to Exchange Online? I just connected via V2 Module and it ran. Do you have the appropriate roles assigned? Did you reconnect after assigning to reload the appropriate cmdlets?
