Cannot open this item. Outlook has already begun transmitting this message

We can see that we are unable to open this item here. This message has already been started to be transmitted by Outlook.

Outlook is a wonderful desktop email client. However, this does not imply that Outlook is the perfect email client. There are a lot of problems that affect all of the different versions of Outlook. One of these problems is that an email that an afflicted user sends out gets caught in the Outbox folder, making it impossible for the user to send, delete, or even open the email. A message of this kind will stubbornly refuse to leave the Outbox, where it will likely remain for what seems like all of eternity. In addition, to add salt to the wound, this issue has already affected and will continue to harm a large number of Outlook customers. When a user who is affected by this issue makes an attempt to resend or open the message that is the source of the problem, they are met with the following error message:

“We are unable to open this item.” This message has already been started to be transmitted by Outlook.

Emails may become stuck in the Outbox for a variety of reasons, including but not limited to their being too large, having a poor internet connection, having an issue with the email itself, or any one of a number of other dozens of potential causes. To our relief, despite the fact that there are a variety of potential causes for this problem, there are also a variety of potential solutions that may be implemented in order to address and resolve it. the following is a list of some of the most effective ways that you may utilise to deal with and solve this problem:

Solution 1: Open the email, then delete it

The first step is to read the email and then delete it.
Start Microsoft Outlook and go to your Outbox folder.
To open the email, simply double-click on its icon. If the email won’t open, skip this step and continue on to the next one in the process. If the email opens without any problems, you can close it.
Simply right-click on the email, then select “Delete” from the context menu that appears.
A helpful hint in the event that this approach does not work for you is to copy and paste the offending email from your Outbox into the Drafts folder on your computer. After that is finished, go to your Drafts folder and either delete the email by double-clicking on it or open it by doing so and then click the Send button to complete the action and send the email. Again, in the event that sending the email from the Drafts folder does not function, it is imperative that you make the effort to delete the message.

Solution 2: attempt to fix the matter in Offline Mode

In the event that Solution 1 was unsuccessful for you, Outlook has a nifty little function called Offline Mode that you can switch to in order to delete the offending email and get rid of the problem. In order to take advantage of this solution, please:
If you’re using Outlook 2007 or an older version that’s still reliable, select File > Work Offline from the menu bar. If you are using Outlook 2010 or a later version, go to the tab labelled Send / Receive, and then click on the Work Offline button.
Attempt to remove the offender’s email from your inbox. To accomplish this, perform Steps 2–4 from Solution 1 once more.
You can even attempt switching to Offline Mode and then utilising the professional tip from Solution 1 to increase the likelihood that you will be able to resolve this issue. This is a backup plan in case the first solution doesn’t work.

Solution 3: attempt to fix the matter in Safe Mode

In addition to working on the issue in Offline Mode, you will also work on the issue in Safe Mode within Outlook. In order to make an effort toward this goal, you should:
Launching Outlook requires that you first press and hold the Ctrl key, and then either double-click on a shortcut to Outlook or click on Outlook itself in your Taskbar or Start Menu.
Keep pressing and holding the Ctrl key until you get a dialogue box asking you if you would like to launch Outlook in Safe Mode. If you do, press and release the key. Once you have reached this dialogue, you can release the Ctrl key by clicking the Yes button.
You can attempt to delete the offending email by using Solution 1’s steps 2–4 once more.
Expert Tip: It is recommended that you make use of the expert Tip that was provided in Solution 1, but at this stage, while you are beginning Outlook in Safe Mode, you should do so.

Solution 4: Create a replacement. PST file then delete the culprit email

If none of the methods presented above have been successful for you, then this solution, which verges on the extreme yet is extremely effective, may be the way to go. After making new.PST files, many users who have been affected by this issue are prepared to delete the emails that have become stranded in their Outbox. In order to take advantage of this solution, please:

If you’re using Outlook 2007 or an older version that’s still reliable, go to the File menu and select New > Outlook Data File…. On the other hand, if you are utilising Outlook 2010 or a later version, go to the File menu, select Account Settings, and then select Account Settings… From there, select the info Files tab, and then click on Add… .
Click the OK button after giving the newly created Outlook file a name such as New PST.
You can make the recently created Outlook file your default by selecting it by clicking on it and then clicking the Set as Default button.
When the resulting dialogue appears, click the OK button.
Restart Microsoft Outlook by shutting the programme and starting it back up again. Once it is opened, you will notice that the contents of your original.PST file are now displayed in Outlook as an additional set of folders. This will be the case once the file has been opened.
You can either delete the email that is stuck in your system by navigating to your secondary Outbox, which is the one from the first.PST file, and deleting it there, or you can move it to your Drafts folder and then delete or resend it from there.
Make sure that your original.PST file is selected as the default Outlook file, and then delete the new.PST file that you made, if that is what you like to do.
Simply restarting Outlook should get everything back up and running again.
Additionally, refer to the Windows host process, rundll32.

Solution 5: Use MFCMAPI to get rid of the culprit message

MFCMAPI is an extremely trustworthy and reliable third-party programme designed as a low-level editing tool for Outlook. It is the only remaining route for you to travel down in the event that all other options are exhausted, and it is the only path for you to undertake and remove the email that was the source of the problem. In order to make an effort toward this goal, you should:

You can get the most recent version of MFCMAPI by going here and downloading it.
If the item that you downloaded is an archive file, you will need to decompress it by using a compression programme such as WinRAR.
To run MFCMAPI, look for an executable file inside the contents of the downloaded file, and then double-click on it.
When the ensuing dialogue appears, select the OK button to continue.
To log in, select Session > Logon….
Choose your Outlook mail profile from the dropdown menu, and then click OK to confirm your selection.
Perform a double click on the entry that already has the value True in its Default Store.
Expand the very first entry on the left-hand side of the window. Depending on whether or not you are utilising an Exchange, this may either be referred to as the Root – Mailbox or the Root Container.
Increase the size of each of the following folders:


The beginning of the Outlook file

The highest level of private Folders

The most recent data store

The objective is to find the folder labelled “Outbox,” and you will complete the task as soon as you expand any of the folders that are listed above and find the folder labelled “Outbox.”
After you have located your Outbox folder, double-clicking on it will cause a window to show up that will display all of the email messages that are located in your Outbox folder.
After picking the offending email by clicking on it to select it, proceed to Actions > Submission > Abort submit.
Click the Actions menu, then select Delete message while the offending email is still selected.
You can choose Permanent Delete passing DELETE HARD DELETE (unrecoverable) by opening the dropdown menu that is located just underneath the Deletion style option and then clicking on the option.
Select the OK button.
After you have closed all of the open MFCMAPI windows and started Outlook, you should be able to see that you have successfully eliminated the offending email.
