Hi ,

We are using exchange 2013 and outlook 2013. Now , I apply a mailbox delegation for user A and User B is able to see his mailbox as he is having a full mailbox access.

Delegation is working fine with web access , https://webmail.abc.com but when I am trying to open the another mailbox inside the outlook its not working

Usvally , if any user is having a full permission of another user , it should be automatically mapped inside outlook , when it opens..but in my case this is not working..

What could be the reason..

Thanks

Hi,

Following cmdlet will help you to see what's wrong with the setup

Get-Mailbox 'name' |fl Name,AutoMapping

If it shows you False, set the automapping property as True and try again

Hi

In your case auto mapping is disabled in Exchange server 2013

Enable Auto mapping through powershell

Add-MailboxPermission -Identity <the shared mailbox> -User <the user> -AccessRight FullAccess -InheritanceType All -Automapping $false<o:p></o:p>

Please look at the below link.

If you want to add delegated user under your mailbox, please do the following

Go To file in outlook -> click account settings-> Click change in email tab -> Click more settings ->Click advanced TAB -> Click add button -> "here type delegated user name" -> click ok -> Click next -> Finish

Now delegated user mailbox will show to under your mailbox.

Advantage of disable Auto Mapping.

Some users have full mailbox permission to lot of mailbox. If auto mapping is on all this mailbox show up their account.

Some users have full mailbox permission for lot of mailbox. If auto mapping is on all this mailbox show up under their mailbox, so it is quiet hard to manage and maintain mailboxes, shared mailboxes, resource mailboxes..

If Auto mapping is disable, they can manually add mailboxes and  maintain very well

Hi,

I noticed you can see the mailbox A in OWA, but you dont see it in outlook.

So we should check the automapping feature, please do the following steps:

1. Open Active Directory Users and Computers.

2. In Users, right-click the Shared mailbox > Properties.

3. In Attribute Editor tab, pick up msExchDelegateListLink attribute.

4. Make sure the value is pointed to the user account who has full access permission to this shared mailbox.

 

If you cant find the msExchDelegateListLink attribute value about User B, please remove full access permission and re-add the full access permission .

 

You can run the following command to add the full access permission and enable automapping:

Add-MailboxPermission -Identity A -User 'B' -AccessRight FullAccess -InheritanceType All -Automapping $true

 

Best Regards,
