I have a small hosting environment running Exchange 2007 with address segregation set-up and working fine. A new client requested a share mailbox for four users. I am only able to add the shared mailbox once I have created the user a mailbox. I get the name cannot be resolved. During the Outlook setup wizzard I am trying to add the shared mailbox as the mail profile - but can only do this once user has a mailbox. I assume the user no being mail enabled doesn't appear in the GAL but the shared mailbox does. Is this normal behaviour? I haven't done a shared mailbox for a long time :)

Do the users have access on the shared mailbox? How do you want them to access the shared mailbox? As a primary profile or by adding as an additional mailbox. If you want it add as additional mailbox then the users must be mailbox enabeld. You have mentioned that the shared mailbox appears in GAL without being mail enabled. How could you create it without an email address?

Rajitha, Share mailbox is mail enabled - appearing in GAL. I'm adding this as a primary mail profile for four users. I cannot however do this until I have created a mailbox (un-used) for the user. Is this normal? Thanks Rob

You login as the user with no mailbox. If you are using Outlook 2007 and start Outlook 2007 it will try to locate the mailbox of the logged in user. Instead, you can go with manual profile creation and provide the server name and shared mailbox email address which should prompt for user credentials. Are you doing it the same way?

This is what I'm doing but it won't find the shared mailbox when they have full permissions to it, unless they also have an email account in addition to AD account. I'm attempting to add it using manual options since as expected it fails if they have a mailbox. Incidentally if you add their email address in AD the auto will also work for a shared email address - but not on this server!

Can you give the properties using Get-Mailbox "Mailbox Name" | fl command? Is the AD account associated with shared mailbox in disabled state. If the mailbox was created as shared mailbox it will have a disabled AD account. If you have created mailbox with recipient type as user mailbox you can try to login with the AD account associated with that mailbox.

Hi, By default, the non-mailbox users are able to configure outlook profile for a shared mailbox. You problem could be caused by the outlook clients issues. When configuring outlook profile, in the "Server" section, please enter the FQDN of the Exchange 2007 server, what's the result? If the issue persists, please log into another computer by the non mailbox account. Then test to see if you can configure outlook profile. If yes, the problem should be in the windows profile. You may need to create a new windows profile for the user.

I have tested with AD account without mailbox and works perfect. You may try from Control Panel->Mail to create a new profile. Try to configure profile for this shared mailbox on any other PC with working outlook.

thanks guys - this seems to be something related to the address book segregation on a DIY hosted environment. For some reason it can't added the shared mailbox until the user has their own mailbox - using mail, wizzard, fqdn etc. Good to know this should be possible in a normal environment, I can only assume the GAL restrictions or something or stopping it resolving the shared mailbox.

Hi rob99, Does the issue persist after logging into another computer by the non-mailbox account? I have seen such problems before and it was caused by the corrupted windows profile.
