    If you are trying to send a large file via Microsoft Outlook and encounter an error stating that the file exceeds the allowable limit, this is likely due to the default attachment size limits set by the type of email account you are using:

    1. Internet Email Accounts (POP3, IMAP, HTTP): The default attachment size limit is 20 megabytes (MB). If you try to attach a file larger than this, you will receive an error message.
    2. Microsoft Exchange Server Email Accounts: The default limit for attachments is typically 10 MB. This limit is set by the Exchange administrator and can be adjusted if necessary.

    To work around this issue, you can:

    • Reduce the size of the attachment, for example, by compressing it into a ZIP file.
    • Upload the file to a shared location and send a link to the recipient instead.

    These methods can help you successfully send larger files without running into size limit errors.

    The best option if the file is too large to be accepted as an attachment to an Email is to log into OneDrive in a web browser (https://onedrive.live.com/), drag the file into OneDrive in the browser and wait for the file to upload, then right click the file in OneDrive and select Share - Get Share Link - Copy Link, then include that link in your Email so the recipient can download the file.

    Another solution is to use a special SMTP server that can detach the attachment and replace it with a download link, allowing users to download the large file from a website. Check https://web.synametrics.com/SynaManInboundSmtp.htm for details.
