Tony, this is from the TDP for Exchange help file: The Exchange Application Client communicates with TSM using the TSM Application Program Interface (API) and with the Exchange Server using the Exchange API. This article was published December 23rd, 1993. Microsoft Mail was Microsoft's mail program when DOS was still being used and they were pushing LAN Manager. PC MAPI: Simple MAPI Common Technical Questions and Answers (Q105964) ---------------------------------------------------------------------------- ---- The information in this article applies to: Microsoft Mail for Windows, version 3.2 ---------------------------------------------------------------------------- ---- SUMMARY Below is a list of common technical questions and answers about Messaging Application Programming Interface (MAPI), from versions 3.0. 3.0b and 3.2 of Microsoft Mail for PC Networks. These articles are from Microsoft's knowledgebase: XADM: Recovering a Single Mailbox from the Online Backup (Q163713) SUMMARY A single mailbox can be recovered from the online backup without having to put the production Microsoft Exchange Server computer offline. MORE INFORMATION To recover the mailbox, you must have a Windows NT computer with enough capacity to install Microsoft Exchange Server and to restore the entire private information store database. The following outlines the procedure for single mailbox recovery from the online backup. ************************ XADM: Overview of Maintenance, Backup, and Disaster Recovery for Exchange Server (Q272234) Restoring Individual Items in a Mailbox Sometimes users delete messages but later realize that they should not have deleted them. Because Exchange Server handles backup and restore procedures at the physical page layer, not at the mailbox level, you cannot easily restore individual messages in a mailbox from backup. Some third-party backup programs do allow you to do a "brick backup"; however, they do not use the Exchange Server backup and restore application programming interfaces (APIs) and typically do not perform as well as backups at the physical page layer do. However, there is a way for users to recover messages that they have deleted from a mailbox without having to resort to backups. The Recover Deleted Items feature that comes with Exchange Server 5.5 lets a user retrieve messages from the Deleted Items folder in Outlook if you enable the feature on the server. Note that if you do enable the Recover Deleted Items feature, the server will require additional disk resources to store the deleted items. In a future release, Exchange Server will be extended to allow applications to recover messages even after they have been permanently deleted from the system. -----Original Message----- From: Consiglio, Tony [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 28, 2002 7:15 PM To: [EMAIL PROTECTED] Subject: Re: Exchange TDP 2.2 Restore Question Confused? Actually Mark, what I wrote came straight from M.S. And yes the MAPI is used to do "online" backups. How else would your backup software system (i.e. Arcserve 2000) be able to see the Information Store? As far as the difference of MAPI/API? MAPI's are sub-sets of API's. MAPI just like a AVAPI (or VAPI). MAPI's are not old at all, they are still being used (from 3rd party vendors) so I do not know what you meant by "older Microsoft Mail client". Yes MAPI is the API call that is used to look at the database in a "3 dimensional" sort of way, but it is not M.S.'s MAPI. It is a 3rd party MAPI. However, you do not have to restore "entire" information store in order to get back one or more mailboxes or folders with in a mailbox. You run Exmerge, export to a PST file. That gets backed up as a regular file. You then can go from there as to what you need from that PST file and how you use it. For example: (from personal experience) the mailbox was corrupted. I re-created the mailbox exactly how it was before. Then logged in to initialize the new mailbox, created a personal folder, and imported my entire PST into that personal folder. Then I methodically copied up what I needed. (i.e. inbox, calendar, etc...). Without mincing words, a PST is a personal folder, yes, but you still need a place to import it to, and that place is a "personal folder" in outlook. However, the only problem was the public folders. We still needed an agent for those. As a matter of fact, I have not done testing on how to backup/restore Pub Folders "with-out" and agent. :-( Confidentiality Note: The information transmitted is intended only for the person or entity to whom or which it is addressed and may contain confidential and/or privileged material.
