Exchange Online Upgrades Its Message Tracing Capabilities

Microsoft announced the GA for the new message tracing feature on June 3. The old code will be deprecated in September 2025, so it’s time to update any PowerShell scripts that use the Get-MessageTrace or Get-MessageTraceDetail cmdlets. Upgrading is easy (as demonstrated in two scripts) and shouldn’t take too long, once you find the time to do the work.
