I got this error message by outlook client:
The total attachment size exceeds the limit. Try removing one or more attachments before saving or sending.

But this happen only when i try to drag and drop big mail messagges from a local folder to online folder (inbox or sent)
This no happen is someone send me big size files cause i receive up to 300Mbyte attachments without problem.

There is a different path local files get?
There is a way i can move these messages into my inbox again?
thanks.
