Why Your Outlook Emails Are Stuck In Your Outbox (And How To Fix It) – SlashGear

Another critical consideration for avoiding email congestion in the Outbox is the size of your attachments. Large files can be a significant hurdle in the smooth transmission of emails. To avoid this issue, Outlook will even at times recommend that you put your email attachment on OneDrive, Microsoft’s own cloud storage provider. If that isn’t happening automatically, you can circumvent this problem by using cloud storage services like OneDrive or Google Drive and compressing files into a zip format.

Uploading to a Cloud Storage Service:

1. Access your preferred cloud storage service’s website and sign in to your account.
2. Click on the option to upload new files, usually New or Upload.
3. Locate the large file on your device and start the upload process.
4. Once the upload is complete, find the sharing option for the file, often available by right-clicking the file.
5. Modify the sharing permissions to allow anyone with the link to access the file, then copy the link and put it in your email.

This approach circumvents the issues with large email attachments by shifting the heavy lifting to the cloud service.

To create a zip file, follow these steps:

1. Locate the large file or files on your device.
2. Right-click the file or files, then select Send to (for Windows) or Compress (for Mac).
3. Name your zip file and then attach this newly compressed file to your email.

It’s important to understand that depending on your file type, you may lose some image or video quality when compressing to a zip file. If you got a zip file in the mail, here’s how to unzip it on Mac or Windows.
