Contact not accessible for assistants to send on executives behalf, help!

I need some assistance. I have an associate that had some issues to the point that I had to create a new mailbox and export and import the contents of his mailbox into a new mailbox using the disable and connect feature in Exchange 2010.

However, I thought that the contents would include his contacts as well. Unfortunately that is not the case. I disabled and reconnected him to a brand new mailbox and imported his contents into the new mailbox. Unfortunately when performing testing by logging on as someone that could send email on his behalf, I noticed that I am unable to send an email from his contacts on his behalf because I am unable to select from the address book to select them.

Does anyone have any suggestions for me to to resolve this issue. This is unfortunately my head legal counsel and you do not want his assistance without the ability to send email on his behalf. Here something that is weird... You can see the contacts when logged on as him and from OWA. However, when I open his contacts logged on as myself as someone that can send email on his behalf, I see them. But when I formulate an email, and I select address book, and attempt to select contacts from there I do not see them. They do not show as a contacts list that I can select from under his address book option. Any assistance is greatly appreciated.

However, while exporting and importing the users contents into a new mailbox. I have encountered on issue that I did not count on. The user has assistants that manage his mailbox and unfortunately they are now unable to send email on his behalf using his contacts. I tried modifying and resaving the contacts hoping they will show but they do not. Now I am seeking a solution to this problem. Everything works great for him and when his assistants log on and use his mailbox via OWA. It's almost like a permissions issue, but I cannot identify the issue. They have full delegation access to his contacts. Any suggestions anyone?

It sounds like his Contacts list has not been selected as an Outlook Address Book, but I am not sure how that can happen if it is his main Contacts list.

I would try right-clicking on the Contacts folder in Outlook and going to Properties, then check the Outlook Address Book tab.  The "Show this folder as an e-mail Address Book" checkbox should be ticked.  If not, then tick it.  With the main Contacts folder this box is usually ticked automatically and disabled so that you cannot untick it.

Send an invitation to delegate to Share contact
