Valid questions, will certainly help to provide an insight on “how GRT works for exchange 2010 DAG” for a novice user.
Issue:
GRT Enabled Backup job of Exchange 2010 DAG fails with the following error in the job log:
Error category : Resource Errors
Error : e00002f7 - Cannot extract mailbox messages from the Exchange backup. Review the job log for more information.
Analysis:
As evident from the error message, it cannot extract mailbox messages from the Exchange Backup.
Now to get further insight you must understand a little about how Exchange GRT works.
In general when an Exchange server is backed up with GRT enabled to tape, there are two distinct phases of the backup.
1. Where the data moves from the application server to the media server and then to tape..(This is a Backup of complete Information store using Microsoft API )
2. Where the data on the Exchange server is analyzed for content and saved in the catalogs.(this is when Exchange web services comes into picture.
The account specified for the Backup job logs on to the database with EWS profile and collects the required information.
This requires your VFF filter driver loaded and additionally Account specified for backup is provided with the necessary privileges as per Admin guide: (this account can be, but not restricted to BESA, it can certainly be a separate account for Exchange Backup purpose.)

As this can evidently be a point of failure, I had suggested using the EWS Editor to be used and check for the credentials or possible failures in the EWS module connecting to the DAG node.
The steps will NOT have any implications on the exchange environment; it is merely used as step of isolation.
Just to recapitulate and to ensure if the questions are answered:
Can you explain what has this got to do with the user's problem and what Exchange credentials are you talking about? Why does he has to extract the Exchange credentials?
I think the above content explains it.
Isn't the BESA used to access the mailboxes?
BESA can be used; however it is not mandatory to use BESA.
Can you also provide some Symantec documentation which links the user's problem to what you are asking him to do?
The below mentioned article explains about Backup Exec and Microsoft Exchange Web Services

EWS is a Microsoft proprietary; hence troubleshooting EWS issues may not be documented in Symantec article.
Our goal is to find if EWS profile is created successfully and mailboxes are opened /viewed outside Backup Exec, this is a step for isolating the problem.
