PowerShell Script to Clean Up Erroring OWA Rules A PowerShell script that cleans up erroring OWA (Outlook Web App) rules should follow these steps: Connect to Exchange Online via PowerShell. Retrieve the user mailboxes. Loop through each user mailbox and identify erroring OWA rules. Remove the erroring rules. Here's a sample script to achieve this:  # Connect to Exchange Online $UserCredential = Get-Credential $ExchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection Import-PSSession $ExchangeSession -DisableNameChecking # Retrieve all user mailboxes $Mailboxes = Get-Mailbox -ResultSize Unlimited # Loop through each user mailbox foreach ($Mailbox in $Mailboxes) { Write-Host "Processing mailbox: $($Mailbox.PrimarySmtpAddress)" # Get inbox rules $InboxRules = Get-InboxRule -Mailbox $Mailbox.PrimarySmtpAddress # Loop through each rule foreach ($Rule in $InboxRules) { # Check if the rule is in an error state if ($Rule.RuleErrorActionRequired -eq $true) { Write-Host "Removing erroring rule: $($Rule.Name)" # Remove erroring rule Remove-InboxRule -Mailbox $Mailbox.PrimarySmtpAddress -Identity $Rule.Identity -Confirm:$false } } } # End the Exchange Online session Remove-PSSession $ExchangeSession To run this script, open PowerShell and execute the script file. The script will prompt you for your Office 365 admin credentials, and then it will process each mailbox, removing erroring OWA rules. via Blogger https://ift.tt/lmSR4tu 2023-03-17T12:02:00-09:00
