Outlook is an email service provided by Microsoft. We can use it to send some email messages. Recently, some users reported that Outlook failed to send very large attachments. What should I do?
1. Open the cloud disk software on your computer, and then select the large Outlook attachment to upload to the cloud.
2. Find the file and click the share button. Then we can copy the link to the file.
3. Finally, return to the Outlook application, click the Send File option on the page, and then paste the link you just copied.
