One of the main concerns users have while using any email service provider is that – Will it let me send large files as attachments? Different email providers offer different attachment limits. Gmail allows files of up to 25MB as attachments, Outlook, Hotmail and Yahoo allow 10MB.

It was always tricky when you wanted to send large files as email attachments. Large files may be too large to attach or take too long to upload and send, and sometimes they may even bounce back without reaching the recipient. The Outlook.com team had this in mind and added a feature so users don’t have to face these problems. You can upload files up to 10 GB to OneDrive. Now, how do you use this cool feature?
To send larger files, users must upload files to a file-sharing website and then share the URL with the recipient.
Outlook.com offers a seamless experience when attaching files. You can still send attachments up to 33MB by attaching them to the email itself; for files over 33MB, it now offers a smooth way to send them using OneDrive. You can now use OneDrive to share single files up to even 10GB – or hundreds of smaller ones – in one email!
If you want to use OneDrive or any other cloud service like Google Drive, Dropbox, etc, after you have opened a new email for composing it, click on Attach > Browse cloud locations.

This lets you attach links to files you’ve already uploaded.
Now, let us say you are composing an email in Outlook.com and attach a file using the Upload and share link. If the file is under 33MB, it will attach.
If not you will gently be prodded to Upload and share as a OneDrive link. Clicking in this option, will let you select the large file from your desktop and upload it to OneDrive.

Once the file is attached, Outlook will add a line, ” … has a file to share with you on OneDrive. To view it, click on the link below”.
The receiver, when he clicks on the link will be taken to OneDrive, from where he will be able to download the large attachment.
The beauty of this feature is that you don’t have to leave the mail you are composing and it is so convenient to use that you do not even realize that you are using any other service.
Large attachments may take a long time to upload – and it all depends on your Internet speed.
