Why do Emails Get Stuck in Outbox?

There are many possible reasons for Outlook not being able to send emails and getting stuck in Outbox, and here are some of them-

  • Emails get stuck due to large attachments i.e., the size of the attachment exceeds the size limit allowed, and that either halts or slows down the sending process.
  • Weak internet connectivity or bandwidth.
  • Due to email authentication settings.To screen forged emails i.e. verifying or checking that the email is from the actual sender only, the malicious or deceptive emails are blocked.
  • Opening and viewing that very message or email in Outbox which is in process of sending.
  • The email is marked as viewed in the Outbox due to an installed add-in.
  • The Outlook account is not authenticated by the mail server.
  • The mail server or Outlook becomes offline.
  • The send/receive settings are incorrect, and the email sending gets halted.
  • Outlook is in use with another program. This means the existence of any software on your system which has access to your Outlook data files.
  • The password you typed is wrong or you have changed your email account password.
  • Absence or non-existence of default email account.
  • Antivirus or anti-spam on your system is scanning outgoing mail.

How to Send Emails that Got Stuck in Outlook Outbox?

After knowing all the possible causes of the problem, let’s understand how to resolve it easily.

Before you start with any of the given methods, ensure that the internet connectivity is good. Slow or poor connectivity may hinder sending emails, especially emails having large attachments.If you are experiencing any problem with your current network, immediately change into a strong and stable connection. Now, let us look into the 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 within a few simple clicks which are as follows-

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.

Check Connected or Connected to MS Exchange

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.

Disable Work Offline status

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. But this time, double-check your network, ensure you are connected to the server, and decrease the attachments with the mail. If it leaves the Outbox folder successfully, then your problem is solved.

Method 3: Check the email settings

You may even check the email setting whether you have set the mode of ‘send later’ or ‘delayed sending’. Such delayed sending setting will result in the showing of Outlook emails stuck in Outbox. Either remove this setting or wait till the time of sending is reached.

Method 4: Look for changes in the password

When the password of your email account and Outlook account do not match, then, Outlook emails are stuck in Outbox. Thus, if you change the password for your email account then you must change the password of your Outlook account as well.
