Exch 2010/Outlook 2013 - Accounts limit reached

Question

Trying to connect to mailbox in exchange 2010 with Outlook 2013, got message (translated):
Unable to add another accounts to server Microsoft exchange server.
Maximal allowed number of accounts of server Microsoft exchange server was reached.
If you want to try to configure this account with POP3 or IMAP protocols, click to NEXT button.
Googling for solution but have no luck with translated error message. Anybody have idea? Is there built-in limit to mailboxes in exch 2010 or it is limited by some internal settings? I do not know how I can recognize versions of Exch 2010 but probably
taken from Action pack.

Hi,
To learn more about Exchange 2010 Store Limits:

In addition, Outlook 2013 allows up to 10 Exchange accounts to be configured in a single mail profile by default.
You can modify the relevant Group Policy key for Outlook 2013 to change the number of accounts.
Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Exchange
DWORD: MaxNumExchange 
 Type: REG_DWORD
Values: a number between 1 and 9999
To solve your issue, I recommend you to create a profile to check it:
Close Outlook.
In Control Panel, click or double-click the Mail module.
Under Profiles, click Show Profile.
Click Add.
In the New Profile dialog box, type a name for the profile, and then click OK.
If this issue still exists, please let me know.
