Common Reasons for Outlook Not Sending Emails

There are a number of reasons why emails may regularly get stuck in the Outbox in Microsoft Outlook and hamper seamless communication. Following are some of the usual reasons for this:

Problem with Internet Connectivity: Poor or unstable internet connectivity clogs the process of sending emails, and the emails stay in the Outbox.
Wrong Email Account Settings: Whenever there is some problem with SMTP, POP3, or IMAP settings, sending an email may be interfered with in its course. Mostly, mistakes in the server names, ports, or authentication information lead to failures in delivery.
Too Large Email Attachment: Emails can be stalled while sending large files attached other than the size limit allowed. Most email servers have attachment size limits that are put into place strictly for smooth transmission.
Damaged Outlook Data Files (.pst): Outlook stores its data in PST files.
Conflicts with Add-ins or Third-Party Software: Certain add-ins or software integrations can interfere with Outlook’s functioning, leading to performance issues.

Basic troubleshooting tools like scanpst.exe, Microsoft’s Inbox Repair Tool, can address minor PST file corruption. However, its capabilities are limited to small or less complex issues. For severe corruption or persistent problems, advanced tools like Stellar Repair for Outlook provide a more reliable solution, ensuring comprehensive repair and recovery of Outlook’s data.
