If you're using Outlook, two questions have probably crossed your mind: what is the maximum size of an email, and how can I send a larger file?
These are completely legitimate concerns! Whether for personal or professional use, knowing the sending limits and being able to manage the size of your emails is essential for optimal communication. And honestly, what’s more frustrating than an error message telling you your email didn't send because of a file that's too large?

A note about the said size: it includes not only your attachment but also the text and other elements embedded in the email, such as your professional email signature. Generally, however, these last elements are negligible compared to the size of the attachment.
But why impose a size limit on emails and attachments in Outlook? Don't see this as a Microsoft conspiracy to make your life more difficult! In fact, the company only has your best interests at heart.

Another practical and quick option for sending your larger files is to use a file-sharing service. With Dropbox or WeTransfer, among others, upload your photo/video/experimental art film of 4 hours, then insert the link into your email, and you’re good to go!
For its subscribers, Microsoft offers a file-sharing and real-time collaboration cloud service called OneDrive. With this tool easily accessible from your email, there's no need to get frustrated by error messages due to a file that's too large. Simply upload the file to OneDrive, and your collaborators will have immediate access.
Want to send a file exceeding the standard 25MB limit in an Outlook email? In addition to the methods mentioned below, you can also send the file in multiple parts, if the nature of the file allows it (for example, a video split into several parts).
