  • Updating of the ports by the mail service providers, often causing the end moment challenges and issues.
  • Ensuring that the mails in Outlook have not been put under the option of delayed sending by mistake (thus creating the clutter on Outbox).
  • Ensuring the status of Outlook from the bottom right side of the screen (i.e. connected to the primary server).
  • Troubleshooting the internet connection to determine the speed that might hamper the process.
  • Going to the Send/Receive tab and try resending all of the emails. You can see the status in another dialog box and wait for some time for the mails to get cleared.

Ensuring that Outlook is online

If the status of Outlook at the bottom shows either disconnected or trying to connect, then you can find the root cause of the messages not getting delivered. Just check your internet connection and ensure that it is offering sufficient bandwidth to the Office 365 server for the efficient functioning of Outlook. Try reconnecting the connection in case of issues.

Check the size of the attachment

In various cases, the sizes of the attachment play as the primary culprit. It means that they are the ones causing major issues in the processing of the overall emails. Sometimes, you may exceed the allowable size per mail unintentionally and discover the same on Outbox. Therefore, you can delete the message from there and send the attachments in different small emails.

Resending from the Outbox

If the Outlook settings are configured in a way that the messages cannot go forward without getting checked from Outbox, then you have to apply this method. Go to the Outbox and manually select each of the emails for getting resent.

Changing the password

In some of the cases, the password incompatibility of the email address and Outlook file can also cause such issues. Therefore, to ensure that they are synchronized, go for the following steps:

  • Open Outlook and go for File->Account Settings.
  • Highlight the account whose password needs to change and click on the option.
  • Select the new password and click on Finish to complete the process.

Alternatively, you can go for changing the password of the Outlook file in the following steps:

  • Open Outlook and right-click on the email account.
  • GO for Data File Properties->Advanced->Change Password.
  • Enter the old and new passwords and confirm the changes.
  • Click OK to exit from the window.

Resorting to OST conversion tool

In some of the cases, you can go playing with the OST files of the emails to try for the Inbox Repair Tool. Just use the OST to PST converter tool to split the large files into smaller attachments as per the user requirement. Take the help of your IT expert to ensure that the process is done.
