Editing Email (section)

===Attachment size limitation===
{{Main|Email attachment}}
Email messages may have one or more attachments, which are additional files that are appended to the email. Typical attachments include [[Microsoft Word]] documents, [[PDF]] documents, and scanned images of paper documents. In principle, there is no technical restriction on the size or number of attachments. However, in practice, email clients, [[server (computing)|server]]s, and Internet service providers implement various limitations on the size of files, or complete email – typically to 25MB or less.<ref>{{cite web |url-status=live |url=https://exchangepedia.com/2007/09/exchange-server-2007-setting-message-size-limits.html |title=Set Message Size Limits in Exchange 2010 and Exchange 2007 |archive-url=https://web.archive.org/web/20130212114611/https://exchangepedia.com/2007/09/exchange-server-2007-setting-message-size-limits.html |archive-date=2013-02-12 |first1=Bharat |last1=Suneja |website=Exchangepedia |date=September 10, 2007 }}</ref><ref>{{Cite web |last=Humphries |first=Matthew |date=Jun 29, 2009 |title=Google updates file size limits for Gmail and YouTube |url=https://www.geek.com/articles/news/google-updates-file-size-limits-for-gmail-and-youtube-20090629 |url-status=dead |archive-url=https://web.archive.org/web/20111219141547/https://www.geek.com/articles/news/google-updates-file-size-limits-for-gmail-and-youtube-20090629 |archive-date=Dec 19, 2011 |website=Geek.com}}</ref><ref>[https://mail.google.com/support/bin/answer.py?answer=8770&topic=1517 "Maximum attachment size", Gmail Help.] {{Webarchive|url=https://web.archive.org/web/20111015232245/http://mail.google.com/support/bin/answer.py?answer=8770&topic=1517 |date=October 15, 2011 }}.</ref> Furthermore, due to technical reasons, attachment sizes as seen by these transport systems can differ from what the user sees,<ref>{{cite magazine |last=Walther |first=Henrik |date=January 2009 |url=https://docs.microsoft.com/en-us/previous-versions/technet-magazine/dd314394(v=msdn.10) |title=Mysterious Attachment Size Increases, Replicating Public Folders, and More |magazine=[[TechNet Magazine]] |via=[[Microsoft Docs]] |access-date=2021-11-07}} [https://docs.microsoft.com/en-us/previous-versions/technet-magazine/cc135877(v=msdn.10) Exchange Queue & A].</ref> which can be confusing to senders when trying to assess whether they can safely send a file by email.
