in my office u have Exchange Server mailbox, i keep my entire data in mailbox. but due to accidental deletion of Exchange mailbox i lost access to my account.

As directed by several users i created new account and using Exchange in cached mode but now i cant access previous emails kept in OST file. :( Now what to do???

If you have any inexpensive 3 rd party tool let me know!

you can't use an old ost with a new profile. If system restore is enabled, roll back to when the account worked correctly, disconnect from the network and start outlook. Export the old mailbox to a pst file. Once you are sure all the data is in the pst, you can use system restore to go back to 'today'. OPen the pst file in outlook and move over the items you need.

Otherwise, you will need to use recovery software. I have links to software at
