Send large files with Outlook

You’ll receive an error message if you attempt to attach files larger than the maximum size limit. There are a few ways to work around this size limit, including using a file sharing service or compressing the file.

Outlook limits the size of files you can send. This limit prevents your computer from continually trying to upload very large attachments that exceed the limits of most Internet service providers. For Internet email account. such as Outlook or Gmail, the combined file size limit is 20 megabytes (MB) and for Exchange accounts (business email), the default combined file size limit is 35MB.
