Updated over 6 months ago

By creating a Delegated User Connection with to SigParser, a single connection can access multiple mailboxes, contacts and calendars in your organization.

The mailbox owners do not need to create SigParser accounts or manually connect their mailboxes. You can add or remove mailboxes from your SigParser account.

Recommended for connecting 10+ mailboxes.

Watch the following video for additional information:

    • Admin access for Exchange Admin

    • Have a list of the email addresses you wish to connect and scan in SigParser.

    • You may be required to purchase a new license for this user account

    • If you need additional support, you can schedule a help session HERE. Have the above items configured prior to your scheduled call.


Create a New User

  • NOTE: you will need the login credentials for this user account (username and password) in order to connect the mailbox to SigParser.

    • Display Name: SigParser

    • Username: sigparser

    • Password: save the password you create and use it to connect to SigParser when prompted.
