Google continues to add more storage space so email users can archive older messages rather than having to delete them.
Please note that you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits. For example, if you are sending an attachment to an Elon faculty or staff member, the file cannot be over 15MB.
Faculty/Staff (Microsoft 365)
An email client may limit the size of an individual file attachment to a value much less than the message size limit. For example, in Outlook Web App, the maximum individual file attachment size is 10 MB
