I am trying to open an additional mailboxes from outlook 2010 but the button "Add" in the account settings is greyed.
Windows 7
Office 2010
2 exchange account
1.private exchange server 2010
2.corporate exchange server 2003 (mailbox of another user I want to add is there)

Both servers work correctly on Outlook 2007 (primary mailboxes and additional mailboxes), but for what reason Outlook 2010 greyed the add button ? because of the 2 exchange account ?

Thanks for your help

I noticed the same. I just added an addtional exchange account for the mailbox i tried to add. It seems you can only add additional mailboxes to your first exchange account.

then create second exchange account

outlook 2010 supports up to 3 exchange accounts in one profile, follow the steps to add another account.

Control Panel
Email Accounts
Select Manual configure server settings or additional server types and press next
select Microsoft Exchange or compatible services and press next
fill in the required settings and finish the new account settings
than open the outlook for checking

yes in mine i can still add addition mailboxes to the first one. Mayby try adding them trough the control panel. If not i'd suggest to add it as additional exchange account instead of additional mailbox as mentioned before. As rjunaid79 has said: you have to do this trough the control panel when OL is closed.

I always work through the control panel with outlook closed

What I noticed is indeed, only the first exchange that has been configured on the computer is able to open additional mailboxes (bad luck for me as I setup my private exhange first),
the solution given by rjunaid79 to add an other exchange account is ok only if I have to open 1 additional mailboxes. I intend to open several in the corporate exchange.

Is this a bug or a limitation of the brand new outlook 2010 ?

I think this is alimitation. But as mentioned before you can still create another Exchange account int the profile and let it refer to the other mailbox you want to open. Just use the same server settings as in the other account. This way you don't need to use the addtional mailbox feature.

You could also recreate the outlook profile with the coorperate one first :) Than add the additional mailboxes and than add ur private one.

Again a limitation of Microsoft...and no info about the fact that I had to setup the different exchange accounts in a certain order...
