How to Send Emails that Got Stuck in Outlook Outbox?

After knowing all the possible causes of the problem, let’s see how to resolve it easily. Let’s try these methods one by one.

Method 1: Change the Outlook connection status:

Before moving to the resolution, check the state of the mail server. If the mail server is offline, your email messages will remain in the Outbox folder until the server state changes from offline to online status.

You can quickly check and change the state of the mail server in a few simple clicks.

Step 1: Look in the right-hand corner of Outlook. You will see Connected or Connected to Microsoft Exchange. If it is “Connected,” then the problem is not related to the server status.

Step 2: Suppose the state is Working Offline, then go to Send/Receive tab and click on Work Offline to disable it. After doing this, you will have to send the email again.

Step 3: If the status is Disconnected, check the internet connection and set it right.

Method 2: Try Resending the Email:

If the email is stuck in the Outbox folder, you must try sending it again. If it leaves the Outbox folder successfully, then your problem is solved.

Method 3: Try an OST Conversion Tool:

There are many other manual methods apart from the ones that are mentioned above, like reducing the size of attachments and inputting the password every time you change it. You can also try Inbox Repair Tool as Outlook stores all the information in OST file.

If none of the manual methods works well to resolve the problem, it is highly recommended to use the Kernel for OST to PST tool. The tool works proficiently to resolve corruption and damages in OST files. The OST to PST converter tool works effectively even on large-size OST files and splits them as per the requirement of the user.
