Should I switch to the new Outlook ?

Yes, absolutely.

Strictly speaking, there is no longer a “new Outlook”. Microsoft has already updated the naming and now simply calls it “Outlook”. The old client is called “Outlook Classic” and is currently scheduled to be retired in mid-2029. The original retirement date was planned for 2026. The new Outlook offers several significant advantages

  • It is fast, lightweight and functional, and fits seamlessly into Microsoft’s new app ecosystem
  • ts minimal reliance on local caching helps prevent local drives from filling up. There are no more OST files
  • The new web-based plugin and add-in model is simple, transparent and powerful. The add-ins already available work flawlessly

We like the “new Outlook” and have been using it exclusively within our business for over 18 months, with positive results.

We recommend simply trying the “new Outlook” to see whether it meets your needs.
Common showstoppers include

  • COM add-ins for other business applications, such as ERP systems
    You should press the vendor to provide an updated solution and draw their attention to the retirement date
  • The new Outlook’s limited support for PST files
    If you use these as part of your backup strategy, it may be time to reconsider that strategy
  • Changes to contact management. Microsoft has dropped contact subfolders and now relies entirely on categories.
    Some applications, particularly integrations with third-party systems such as telephone systems, currently still require subfolders

You can switch back to Outlook Classic at any time after trying it.
