That right, the atached file size in office 365 has been enlarged from 25MB (Which is usually enough for most people) to 150MB.
That means that you can now send and receive 150MB file attachments using office 365.
However take note, the default size is still 25MB and to take advantage of the 150MB file limit the office 365 admin must modify the default settings.
You can change the default for your organization by adjusting the default message size restriction. Simply select recipients > mailboxes then click “. . .” and select Set default message size restrictions.
So go ahead and take advantage of the new 150MB file size limit.
