(Applies to: Epicenter Server)

Symptom: You receive an error message in Epicenter Server similar to this:

12/16/15 09:57:33 [Global Address List] Unable to open the mailbox for Xxxx Yyyyy <yyy@example.com>. Reason: Unspecified error . Support Info: ecNoReadRight

Most often seen with Outlook 2010 and Outlook 2013 on Office 365.

Cause: Usually caused by Outlook using the HttpMapi protocol.

Solution:

Please check the following. These instructions only apply to Office 365 and other Hosted Exchange environments. This error typically does not happen with dedicated Exchange Servers.

  • Make sure you can open a remote mailbox in Outlook using the instructions on this page.

    If you can't open it, then follow the instructions above to configure Full Access to mailboxes.

  • Look in Tools | Exchange Privileges and make sure it's set to Epicenter has privileges that Exchange will determine.

  • Outlook 2013: You must run version 15.0.4815.1002 or later. (As of April 2020, the latest tested version is 15.0.5215.1000). To see the version in Outlook 2013, select File | Office Account | About Outlook. Also, in Epicenter Server, look under Tools | Exchange Privileges - the checkbox at the bottom for Disable mailbox location optimization must NOT be checked, despite the comment in parentheses.
