FIX: Imported or Copied IMAP Email Messages are Missing on Exchange (Outlook & Office365).

Last updated on November 25th, 2020

A few days ago, I was asked by one of my clients, to set up his new Office 365 email (Exchange) account on his PC in Outlook, and to transfer all the emails from the existing IMAP account to the new one (Exchange). However, after transferring the IMAP folders and email messages to Office365 (Exchange) using the Outlook 2016 application, we realized that some IMAP folders are empty and do not display the email messages that were transferred.

FIX: Imported or Copied Email Messages on IMAP are Missing

If you have setup your IMAP account in Outlook and you cannot see all (or some) messages under the IMAP folders, then continue below to fix the problem. This tutorial contains instructions to resolve the following problems in Outlook 2019, 2016 or 2013:

  • After you have imported an existing Outlook PST file, or after you have copied/moved your email messages to your IMAP account's folders, you realize that the IMAP folders doesn't contain any messages or you cannot see all of them.
  • After you have accidentally deleted a message from IMAP, you cannot find the message on the Trash (Deleted Items) folder.

How to FIX: IMAP Doesn't Show the Imported or the Deleted Email Messages.

The above mentioned problem appears because when transferring (or when exporting/importing) messages from an IMAP account, Outlook maintains the IMAP folder properties and by default hides the transferred messages (and the transferred folders), by setting the default view on all IMAP folders to "Hide Messages Marked for Deletion". The same problem also occurs when you transfer messages from the IMAP mailbox to a local PST data file.

To show all the IMAP folders and messages:

1. Select the IMAP folder, that doesn't display the messages.

2. Select the View tab and click Change View > IMAP messages.

4. Click Change View again but now choose Apply Current View to Other Mail Folders.
