Although the default Mail app has improved with the latest macOS Ventura update, most users prefer Microsoft Outlook to handle emails. Microsoft has done a solid job with a native Outlook app on Mac. But it’s not perfect. Sometimes, Outlook fails to send attachments with an email. If you frequently face the same, here are the ways to fix Outlook not sending attachments on Mac.
You can always move to Outlook for the web to complete the job. But nothing beats a native Outlook experience on Mac. Instead of settling with a below-average web client, use troubleshooting tricks to send emails with attachments.
1. Check Network Connection
If your Mac is facing network issues, Outlook won’t send attachments. You should ensure a robust Wi-Fi connection on your Mac. Click Control Center at the top and enable Wi-Fi on your Mac. You should connect to a 5GHz Wi-Fi network and send attachments on Outlook.
2. Force Restart Outlook
Before we move to advanced tricks to fix the problem, you should force restart Outlook and try sending the attachment again.
Step 1: Press the Command + Space keys and search for Activity Monitor. Hit Return to open the app.
Step 2: Select Microsoft Outlook from the list. Click ‘x’ mark at the top to close the app.
Open Outlook again and send attachments without any problem. If the issue persists, move to other troubleshooting tricks.
3. Check the Attachment Size
Outlook and Gmail email providers limit attachment size to 25 MB only. If you try to send a large file over Outlook, you will continue to face errors. Here’s how you can check file size on Mac.

Step 2: Select File at the top and click Export.
Step 3: Use the Quality slider to compress the picture or video.
Step 4: Make sure to reduce file size below 25 MB and click Save.
Launch Outlook and try sending the attachment over email again.
4. Double Check Email Address
You should double-check the typed email address in Outlook for Mac. A small typo in the email address can lead to Outlook not sending attachments issue. You can’t even send a normal email due to an incorrect recipient address.
