====== Multiple Exchange Mailboxes ======

There are various reasons that a user might need to manage two Exchange mailboxes.

  * Boss/Executive Secretary
  * Shared Mailbox/Personal Mailbox
  * Two Personal Mailboxes/Companies

<note tip>In the following, the 'first mailbox' would just be the main account in use (probably already configured in Outlook or OWA).  The 'second mailbox' is just another set of folders (mailbox) the user wants to see shown below their primary folders (mailbox) in Outlook or OWA.  The choice of 'first' and 'second' is arbitrary.</note>

<note>This allows an Outlook or OWA user to log in with only the **first mailbox** credentials while **managing multiple accounts** (mailboxes).</note>

===== Permissions =====

Modify the **second mailbox** permissions so the first mailbox (account) has **Full Access** and **SendAs** permissions:

**Exchange Admin Center -> Recipients -> Mailboxes -> <mailbox> -> Edit**

**Mailbox Delegation -> SendAs -> Add the First Account** 

**Mailbox Delegation -> Full Access -> Add the First Account**

===== Outlook =====

The **second mailbox** folders will automatically appear in the navigation pane below the **first mailbox** (primary) folders.

===== OWA =====

**Outlook Web App -> Right-Click First Account (top level folder) -> Add Shared Folder -> Name/E-Mail of Second Acount**

Adding the shared folders to OWA:
