Sharepoint 2013 vs Exchange 2010 SP3 search (Error while crawling LOB contents)

Question

Hi there:
We are trying to solve the problem: ERROR CRAWLING LOB CONTENTS when we wish to search Exchange 2010 SP3 public folder content on Sharepoint 2013 Foundation.
Quick briefing:
Followed this instructions:
http://technet.microsoft.com/en-us/library/jj591608(v=office.15).aspx
* Created CRAWL RULE
- Used Domain Admin for content access ---> IS THIS WRONG?
- Domain Admin can access public folder thru Outlook Web Access (checked)
- Included all items in this path

* Added a content source for Exchange Server public folders
- Logged to Outlook Web Access with domain admin, expanded Public folders and opened 1st subfolder in new window and copied the address
- Logged to Outlook Web Access with domain admin, expanded Public folders and opened 2nd subfolder in new window and copied the address

* Did a FULL CRAWL
PROBLEM:
- Search results does not throw "correct data". Some items are not being found
CRAWL LOG is reporting: Error while crawling LOB contents
Detailed error message:

Try again later.; SearchID = 4E8542D3-48EF-404E-8025-8D9AAEFE777A )
We thought it's a throttling issue / found possible solution:

Hi Bostjan,
From the error message, the issue might be caused by throttling policy on Exchange side. And the article you posted provides the right solution, some modification to the solution and please try again.
For throttling policy part
1.Execute the command for Set-ThrottlingPolicy
Set-ThrottlingPolicy SharePoint -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited
2.Execute the command Get-ThrottlingPolicy SharePoint to double confirm the policy setting has been successfully executed
For registry key part
1. Start Registry Editor (regedit).
2. Navigate to the following registry subkey:
\\HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
3. Right-click ParametersSystem, point to New, and then click Key.
A new key is created in the console tree.
4. Rename the key MaxObjsPerMapiSession, and then press Enter.
5. Right-click MaxObjsPerMapiSession, point to New, and then click DWORD (32-bit) Value.
The new value is created in the result pane.
6. Rename the key to <Object_type>, where <Object_type> is the name of the registry object type that you're modifying. For example, to modify the number of messages that can be opened, use objtMessage. Press Enter.
7. Right-click the newly created key, and then click Modify.
8. In the Value data box, type the number of objects that you want to limit this entry to, and then click OK. For example, type 350 to increase the value for the object.
9. Restart the Microsoft Exchange Information Store service.
If it still doesn’t help, please check ULS log for related error message.
