OL 2003 and later versions are using pst format and it does capable of storing unicode data (i.e. emails, contacts, calendar & more) and of course actually there is no theoretical size limit but if u want to know as practical, the limit is 20 GB (u can configure). Ucan check by clicking mailbox > <username> properties for mailbox and click folder size….. check here for conf and mofe info

Is mailing limit in out look…
Outlook is client software. I don’t know what limits it might have.
But it doesn’t really matter because it is the servers that determine the limits. The server that sends your e-mail and the server that is used by the recipient will both have limits. Either one might have a smaller limit. Your client won’t make any difference.
… is as well as yahoo mail(25 MB).
IMO, 25MB is already too large for e-mails. E-mail servers are for handling mail, not for file transfers. Use a file transfer protocol if you want to send files.
