Office Password Recovery Toolbox Description:

Office Password Recovery Toolbox is a comprehensive solution for recovering MS Word, Excel, Outlook and Access passwords.

IMPORTANT: One license includes the online decryption support for two MS Word or Excel documents protected with "open" password and the unlimited use for other password types. Each time you decrypt MS Word or Excel document protected with an "open" password, one decryption credit will be subtracted from your registration code. When you run out of credits, you will not be able to decrypt documents entirely, though you will be able to remove and recover passwords of other types. If you need to remove "open" passwords for more documents, you will need to purchase additional credits.
