The Migration Impact of Office 365’s Max Message Size Increase from 25MB to 150MB

A lot of customers that I speak with on a daily basis are looking to migrate to Office 365 from a third-party hosting provider. In these types of environments, the hosting provider typically does not provide the rights required to migrate to Office 365 with the New-MoveRequest PowerShell cmdlet. This means that EWS or MAPI are often used as the transport mechanism to copy user mailbox data from the source hosted environment to Office 365.

The problem with this ‘copy’ based migration method is that the largest email message that could be moved into Exchange Online was 25MB. If you tried to move items larger than 25MB into Office 365 those messages would be rejected. As you can imagine – it is not hard to find users that have attachments in their mailbox that are larger than 25MB! Think about all those large PowerPoint slide decks, spreadsheets and videos that you have in “your” mailbox today!


But there is good news…

Partner Enablement – How We Know When It’s Working
Posted by Pete Caldecourt, Sales Engineering Manager

Click to see full sizeMost software solution providers have some type of partner program, but not all programs are created equally. At Binary Tree, we take the relationship between our technical staff and partners very seriously. So much so, that we completely revamped our partner program about a year ago. And we’re writing about it now because we are certain that it’s working.

Naturally, we want our partners to have a good understanding of our solutions, get access to training and support materials, be able to improve delivery, and ultimately make more money. But how do you build a true community – one where partners collaborate with each other?
