How long does it take to import MSG file to iCloud Mail?

If you are looking to import MSG files to iCloud Mail does not have a fixed time because iCloud does not natively support MSG format and requires conversion or migration through an email client such as Apple Mail or Outlook. Typically, the process involves converting MSG files to a compatible format like EML or PST, then importing them into iCloud via IMAP sync or drag-and-drop in Mail app. Time varies depending on file size, number of emails, attachment weight, and internet speed during iCloud synchronization. Small batches may take a few minutes, while large mailboxes can take several hours including upload and indexing. Using a stable Wi-Fi connection and pre-converting MSG files significantly reduces total migration time. Delays can also occur if iCloud servers are busy or if attachments are very large or numerous. Overall, expect variable time depending on conditions involved here.

If you are wondering how long it takes to import MSG files to iCloud Mail, there is no single fixed answer. The time depends on several factors — how many MSG files you have, their individual sizes, and most importantly the method or tool you are using to handle the entire process.
