Office 365 Attachment size and Message size limits.

What is the attachment size and message size limits for Office 365? I am getting mixed answers and would like to find the official Microsoft reference to this.

Sometimes I hear that there is a 35 MB message size limit. Other times, I hear there is a 25 MB message size limit. For attachments, I hear there is a 10 MB attachment size limit but the attachment limit cannot exceed the message size limit.

By the way, Just in case.... is the answer different between EWS (Exchange Web Services) or MAPI (RCP over HTTPS)?

If you know what the official word on attachment size limits and message size limits in Office 365 then please let me know.

35 MB is the encoded size, the 'normal' size is around 25. The 10 MB limit for attachments is for OWA only.

Email size limit is 25M per message, the attachment file size is actually 10M
