In this episode, the panel discusses the following community question:

“I have a client I recently took on who has Exchange 2010 which I'm going to migrate to Office 365. The issue is someone in the past has lifted the message size restriction and they have email's over 150Mb! Office 365 doesn't support messages this size so unable to import them.  Has anyone come across this and what solution have you used, other than opening each mailbox searching for large emails manually exporting them, and then saving them somewhere. There are a lot of mailboxes including users who have left so not a slick process and being Exchange 2010."
