After a busy week of migration of data from the lotus notes to the O365, we noticed that some of the users couldn’t able to download / upload a large file (>10MB) size. After a quick google, came across this post “SharePoint Downloads Interrupted For large Files” with a solution to it.
As mentioned in the blog, “netsh interface tcp set global autotuninglevel=disabled” did the trick. More details about it can be found here : http://support.microsoft.com/kb/947239
