There are two options for setting up an Exchange connection to multiple mailboxes. Delegated or Impersonation. Delegated is more restrictive and generally what most companies choose to go with.
Exchange Delegated Access
Delegated access grants a user account access to another user or multiple user's email accounts. This is good when you don't want to setup your entire organization in SigParser. Each time you add a mailbox you'll need to turn on delegated access and then manage the list of mailboxes SigParser is watching.
In Exchange create a new user for SigParser
In Exchange go each each of the mailboxes SigParser will need to be able to access.
Go to the Users list
Click on the user name
Under Exchange menu on the left click Full access and send as
Type in the email address for the SigParser User you created and grant full access
Wait 20 minutes for Exchange permissions to catchup.

Exchange Impersonation (less common option)
Exchange Impersonation approach you can configure one Exchange account to access all mailboxes for an entire organization. This is nice if you know you want to monitor every employee and makes adding new mailboxes as simple as just adding them mailbox to the list in SigParser instead of having to touch both Exchange and SigParser for each new mailbox monitored.
To use impersonation
In Exchange create a new "Admin" role
In Exchange, assign to the new role the “ApplicationImpersonation” management role.
In Exchange, create a new user for SigParser and assign that user the new role you just created which allows impersonation.

Connect the "SigParser" Exchange user you just created to SigParser.
Click Mailboxes -> Add Mailbox -> Add for Exchange
Authenticate as the SigParser user account you just setup in Exchange.

Click the name of the connection you just setup.
Paste or type a list of mailboxes into the textbox.
