About Outlook RPC over HTTP and Outlook Anywhere configurations

This section provides overview information about access to Enterprise Vault from Outlook RPC over HTTP clients and Outlook Anywhere clients. References are provided to other sections where you can find more detailed instructions on configuration tasks.

Outlook 2007 and Outlook 2003 users can access mailboxes using remote procedure call (RPC) over HTTP. With this protocol, MAPI is used to tunnel Outlook RPC requests inside an HTTP session. Using RPC over HTTP remote Outlook users can connect to Exchange Server mailboxes without the requirement for OWA or a virtual private network (VPN) connection.

In an Exchange Server 2007 environment, when Outlook is configured to use RPC over HTTP, the feature is called Outlook Anywhere.

With RPC over HTTP enabled, Enterprise Vault Outlook Add-Ins can perform the following actions:

View archived items
Archive items manually
Restore archived items.
Delete archived items.
Search archives using Integrated Search . (Browser Search link is not available).
Use Archive Explorer.
Use Vault Cache.
Perform client-side PST migrations.

Note:

With RPC over HTTP, the Enterprise Vault Outlook Add-Ins automatically behave like the Enterprise Vault HTTP-only Outlook Add-Ins. The user is not able to select a different archive or retention category when they archive an item manually.
