Cannot restore mailbox with error e0000388 - Cannot log on to EWS with the specified credentials

Hi all,

 

When we tried to restore the items from the backup. it have error "Error : e0000388 - Cannot log on to EWS with the specified credentials. Review the resource credentials for the job, and then run the job again."

I checked the system account assigned required permission and not hidden as the document "https://www.veritas.com/support/en_US/article.100008492" . But the error still exist

 

Best Regards

Andy

Re: Cannot restore mailbox with error e0000388 - Cannot log on to EWS with the specified credentials

So you have met all the following requirements from above link?

 

  1. The account must be an Exchange Full Administrator (Exchange 2003), Exchange Organization Administrator (Exchange 2007), and Organization Management (Exchange 2010) at the top level of Exchange.
  2. The account must be a Domain Administrator. (Recommended, ensure that Domain Admins is a member of the Local Administrator's group on the Exchange Server)
  3. The account must have an active mailbox on the Exchange Server.
  4. The account must have received an e-mail via the mailbox.
  5. The account must have sent an e-mail via the mailbox.
  6. The account must be named so that it is unique within 4 characters. (Refer to the article below for steps to test this).
  7. The account must be visible to the Global Address List, "Unhidden". (See below for instruction on verification of G.A.L. status)
  8. Make sure the default system logon account of Backup Exec and Backup Exec Service Account are the same.

What is your backup exec and exchange version?

Seem 20.6 will fix the problem

https://www.veritas.com/support/en_US/article.100046761

Error from EWS_Output log:

Error              : System.Net.WebException: The remote server returned an error: (401) Unauthorized.
                        at System.Net.HttpWebRequest.GetResponse()

Hi Marianne

Yes. I checked both link.

The first link is it will fixed in 20.6, but my version is 15. Do version 15 cannot perform GRT restore in exchange 2013

The second link is related to exchange TLS. Our exchange disabled TLS and try the registry but not work
