this is, because the user that will open another mailbox does not have the appropriate rights on that mailbox... You have to give the access-rights in the Exchange-Enabled Active Directory Console (open this on the exchange server under Programs, MS Exchange Server 2003). Ther you can give the rights to another user. Be sure, the user is not member of domain admins or enterprise admins. in that case, it is not possible to open other mailboxes, because this groups are denied to read other mailboxes by default!

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Can you try to grant read/write right to each folder (Inbox, Sent Items, etc)
Try granting rights to the top level of the mailbox.  Have the other user right-click the top level (Mailbox - <display name>) from Outlook and select Sharing and add reviewer permissions.  This should allow the other user to expand the mailbox from the folder list.
It is NOT possible to connect other mailboxes using a user which is in the group of domain admins or enterprise admins! This two groups explicitly have a DENY on the whole Mailbox-Store. this is designed by Microsoft for Security Reasons! You should remove your account from these two groups and give the rights for your account to the desired Mailbox. So it works... Remember: DENY alltimes comes before Apply! So you can set 10 times full access rights to a user: as long as the user is in a group that has a deny, you have no chance! I suggest to create a second user for administrative purposes and give your standard user just the standard rights.
