There are times I needed to export my rules to a human readable form. This comes very handy. If you haven’t installed the ExchangeOnline module, you can follow https://learn.microsoft.com/en-us/powershell/exchange/connect-to-exchange-online-powershell?view=exchange-ps

Open a Powershell window, then:

Connect-ExchangeOnline
Get-InboxRule -Mailbox user1| Select-Object Name,Description,Enabled,RedirectTo, MoveToFolder,ForwardTo | Export-CSV C:\temp\RulesOutput.csv -NoTypeInformation -Append

This exports your rules to a CSV file in c:\temp
