  3. Now, open Outlook and head to File > Import and choose the exported Entourage archive (.rge).
  4. Next, press on File > Export and select the mailbox folders. Then, export them as an OLM file.

Step 02: Convert Entourage to PST

  1. First, set up an IMAP-enabled email account in Outlook for Mac.
