Remove rules with command Remove-InboxRule

Question

I would like to remove by filtering " Filter * " a massive rules. Have this command but can't run correctly

Remove-InboxRule -Mailbox user@domain.com -Identity 'Filter *' -Confirm:$false

Is it possible?

Answer 1

If I'm reading this correctly you want to remove all rules from a mailbox. The identity parameter doesn't allow for wildcards, so in that regard there is no filtering capability. -Identity does support pipeline input, so you can however pipe the results of Get-InboxRule:

Get-Mailbox user@domain.com | Get-InboxRule | Remove-InboxRule -WhatIf

OR:

Get-InboxRule -Mailbox user@domain.com | Remove-InboxRule -WhatIf

You can insert additional filtering via a Where clause between Get-InboxRule and Remove-InboxRule:

Example:

Get-Mailbox user@domain.com | Get-InboxRule | Where{$_.MoveToFolder -eq "Junk E-Mail"} | Remove-InboxRule -WhatIf

I have to caution you that any rules that had been un-checked in Outlook will get deleted any time you change rules from the shell I've worked on this a lot in the past and the only API that seems not to have this issue is the Outlook Object Model. ESM, EWS, CDO & RDO (deprecated as they are) all have the same issue. So if you are just trying to wipe everything you're good, but if you're filtering first, exercise caution.
