Microsoft's Outlook is one of the most popular email servers and management applications available. Needless to say, it is extremely popular due to the fact that it provides such dependable and efficient support. However, there are times when users experience unwelcome issues with their Outlook accounts. One of these issues is the Outlook app not receiving/sending emails, which can be caused by a variety of factors.
When Outlook is not able to send or receive emails, It can be due to several reasons: -
- An Outlook Add-In that isn't working
- Incorrect email configuration
- Security software is preventing email delivery.
- A tainted Outlook profiles
- The Outlook application has a problem.
What should you do if Outlook isn't receiving or sending emails?
Is Outlook unavailable? Examine the very bottom of your Outlook window.
If you see Disconnected, Working Offline, or trying to connect..., Outlook is unable to connect to the email server and send your message. Toggle between offline and online mode by selecting Send/Receive > Preferences > Work Offline. You may need to reopen the message and resend it, or select Send/Receive.
Make certain check that you are connected to the Internet.
Outlook will be unable to send messages if your internet connection is lost. Launch a browser like Internet Explorer, Edge, or Chrome. Enter any of the websites in the address bar and see what happens. If you are unable to access either of these websites, Fix your network connection problems.
Do your emails have large attachments?
Some email providers (including your ISP and even Gmail) will not allow you to send messages that are larger than a certain size. Go to your Outbox and then open the email messages that have become stuck. Begin with the most recent message. If the attachment in that message is larger than 5MB, delete it and replace it with a smaller file. For more information on attachments, see Attach a file to an email in Outlook.
Restore the Outlook program
The Outlook program may need to be repaired on occasion. Repairing is a simple process that can take up to 30 minutes to complete. See Repair an Office application for more information.
Contact the help desk for your antivirus software.
Email scanning is a feature of some antivirus programs. If a virus is discovered, your antivirus software may prevent you from sending or receiving email until the virus is removed.
Launch Outlook in safe mode.
Occasionally, one of Outlook's add-ins will crash, preventing your email messages from being sent. You can start Outlook in safe mode to disable all add-ins. If you can send an email while Outlook is in safe mode, creating a new Outlook email profile should let you do so again.
To launch Outlook in safe mode, press the Windows key. Type outlook.exe /safe into the search box and press Enter.
Run the Inbox Repair Tool
For many types of email accounts, Outlook stores your messages in a Personal Folders File (.pst file). You can repair this file by running the Inbox Repair Tool. This repair should take approximately fifteen minutes. For more information, see Repair your Outlook personal folders file (.pst).
