Error Message

2017-09-99 99:99:99,188 [7616] ERROR ngeAutoDiscovery - System.Net.WebException: The remote server returned an error: (401) Unauthorized.

Cause

When an O365 collection is performed, the source account domain is appended in the mail profile to match the domain of the source mailbox

Example:
  • Source Account = administrator@domain1.com
  • Target Mailbox = user1@domain2.com
  • Mail Profile Account = administrator@domain2.com

Resolution

The ESA Property "esa.icp.exchange.online.sao365emailId." can be used to set up different source account for separate O365 tenants (domains).

Example:
O365 colleciton source account = bob@domain.com
ESA Property = esa.icp.exchange.online.sao365emailId.bob
Value = bob@domain.com

Usage:
  • Notate the source account to be used for O365 collections
    • This source account will need to be granted full access permissions to all O365 mailboxes
  • Go to System > Support Features > Property Browser
  • For Select the case (or system) select System
  • In the Name of property to change field, type in esa.icp.exchange.online.sao365emailId.
    • In the "" part of the property, only enter the on-premise domain user account name and not the domain
    • Example: esa.icp.exchange.online.sao365emailId.bob
  • In the New value (leave blank to remove) field type in the account name with the domain
    • Example: bob@domain.com
  • Click Submit

Issue/Introduction

The O365 collection source contains a mixture of mailboxes that have different tenants (domains). The source account for the collection can collect from mailboxes that share the same tenant (domain) as the source account, but fails to collect from the other mailboxes even though the source account has full permissions.

Example:
  • Source Account = administrator@domain1.com
    • Mailbox 1 = user1@domain1.com - Collection successful
    • Mailbox 2 = user2@domain1.com - Collection successful
    • Mailbox 3 = user3@domain2.com - Collection fails
    • Mailbox 4 = user4@domain3.com - Collection fails
