# How do I add another user's inbox to my favorite list in Outlook 2010?

Every time I need to access another user's inbox in Outlook 2010, I need to go to File | Open | Other User's Folder. Obviously, this is very time consuming.

If possible, I need a quicker way to access it, without adding the mailbox to the "open these additional mailboxes" list (user doesn't have full access to mailbox). Is there a quicker way?

If it's a .pst file, it will appear as a seperate Mailbox. Well, if you had another mailbox to your tree, it will also appear as another seperate mailbox. –  r0ca Sep 21 '10 at 14:03
@r0ca It's not a .pst file, it is another user's inbox on the Exchange server. –  Nate Pinchot Sep 21 '10 at 15:03
For starters, do you have full permission on <Inbox> and all of it's child items? –  EvilChookie Sep 21 '10 at 23:02
@EvilChookie Definitely. I can open the folder no problem with File | Open | Other User's Folder (as per the question). The issue is I need to add this to the favorites or some other way to quickly access it so I don't have to do File | Open | Other User's Folder to access it each time. –  Nate Pinchot Sep 22 '10 at 13:38

This problem confounded me, too, but I've found the answer!

1. Go to File > Account Settings > Account Settings.

2. Select the Email tab and double click on your profile. Click the icon for More Settings..

3. Go to the Advanced tab and click the Add... button. Type in the name of the user as it appears in your Exchange Global Address List.

4. Click Apply, then OK. Close the remaining dialog box.

5. The new inboxe(s) will appear in your folder list.

To then make it a favorite, right click the folder and select Show in Favourites or drag the particular folder (Inbox, Sent items, etc.) up to your Favorites and it will open every time.

Thanks. I no longer use Outlook 2010 but if someone confirms this I'll mark it as the accepted answer. –  Nate Pinchot Sep 25 '12 at 22:53
This is the correct way to do it Outlook 2010. –  Goyuix Oct 16 '13 at 18:19

You first have to provide full access permissions on the Exchange server, then follow the instructions below.

Just go to Tools » Account Settings. Click on your email and then click on Change. Click on More Settings » Advanced tab, and in the Mailboxes type the name of the user mailbox and click on Add.

After that, the user’s Mailbox will appear in your mail folders.

This works in Outlook 2010 as well. –  MikeW Dec 17 '12 at 18:15

Sadly it just isn't possible in Outlook 2010. Adding another mailbox is the only way.

I'm marking this as the answer since this is the most correct answer to the question. –  Nate Pinchot Apr 27 '12 at 15:16

Add the Mailbox as an additional mailbox. Set up Outlook delegation so that the users have read-only access.

On the AD/Exchange Mailbox rights, give the users read access.

On Sent Items, and folders other than Inbox, set the permissions to custom.

Folder Visible, Delete and Edit Items - none.

I don't really want to add it as an additional mailbox, due to space concerns and having an SSD. This is because Outlook forces all mailboxes to have the same cache mode settings. –  Nate Pinchot Oct 28 '11 at 21:42

Did a couple quick tests since I was looking for the same answer.

That being said, I was surprised to see all the answers of "you need full access to the mailbox." That's just not true.

If you only want to see the inbox, grant the user whatever level of access you feel comfortable with to the inbox folder. Then, on the top level (where it has the email address or mailbox name), right click and select Data File Properties (2010) or Properties (2007 and earlier). Select the permissions tab. Grant only Reviewer access to the "top" of the mailbox.

Now, if you add using "Additional Mailboxes to open", you will only see the folders under the mailbox you have been granted access to.

You need to do the following:

• Click File | Info
• Click Account Settings | Account Settings
• Click the E-mail tab and select your Exchange account
• Click the "Change..." toolbar button
• Click "More Settings..."
• Type in the name of the account you want to access and click OK
• Repeat as needed
• Dismiss all open dialog boxes
• You may need to close and reopen Outlook for the changes to take effect (I didn't need to)

Of course, you will need permissions to the inbox first. If you need access to many inboxes, you probably want to set the inbox as a "Favorite".

I think you misread the question. The question asks how to add another user's inbox to favorites without adding the mailbox to the "open these additional mailboxes" list. –  Nate Pinchot Mar 23 '12 at 20:19
But the title of the question asks how to add it to the Favorites. I believe this is the only way. –  JackAce Mar 23 '12 at 21:27

While this will not add the folder to the favourites, you can get quick access to another user's folder by creating a new button in the menu bar pointing to this macro:

Sub OpenSharedInbox()
Dim myOlApp As Outlook.Application
Dim myNamespace As Outlook.namespace
Dim myRecipient As Outlook.recipient
Dim myFolder As Outlook.MAPIFolder

Set myOlApp = CreateObject("Outlook.Application")
Set myNamespace = myOlApp.GetNamespace("MAPI")
myRecipient.Resolve
If myRecipient.Resolved Then
Set myFolder = myNamespace.GetSharedDefaultFolder(myRecipient, olFolderInbox)

' This open the folder in the current window
Set myOlApp.ActiveExplorer.CurrentFolder = myFolder
' This open the folder in a new window
' myFolder.Display
End If
End Sub

-

very simple! Just use:

add-mailboxfolderpermission username:\inbox (or any other folder you need) -user mailbox -accessrights editor/owner/reviewer


Then you'll need to do this again as username only.

This will make sure you give rights to the username:\top of information store which is what outlook needs to be able to "pin" it to outlook or make it sticky without having to add the folder all the time.
