Hey Guys

I am trying to edit a mailbox's email addresses (proxyAddressCollection). when adding a new SMTP address in this field it gets set as Primary. how to make other one Primary in the Variable itself then set in the mailbox?

Here is what i am trying...

$mb = Get-Mailbox -id "User"
$mb.emailaddresses.Add("SMTP:newemailID")
$mb.emailaddresses.makeprimary(SMTP:oldemailID")

It gives me an error below.

Cannot convert argument "0", with value: "SMTP:oldemailID", for "MakePrimary" to type "System.Int32": "Cannot convert value "SMTP:OldEmailID" to type "System.Int32". Error: "Input string was not in a correct format.""
At line:1 char:31
+ $mb.emailaddresses.MakePrimary <<<< ("SMTP:OldemailID")

Any Ideas...

Thanks in advance.

is it possible guys??

It's giving you an error becuase you are trying to pass a string to the method, and it's expecting an integer. Use the index of the email address in the $mb.emailaddresses array:

$mb.emailaddresses.makeprimary(0)

Don't forget when you are done you still need to use set-mailbox to set the email address values:

Set-Mailbox username -EmailAddresses $mb.emailaddresses

Another thing to mention...you can pass an array of emailaddresses to Set-Mailbox -EmailAddress and by default it will set the first address as the primary, for example:

Set-Mailbox username -EmailAddresses "user@domain.local","username@domain.local"

or...

This would add an additional email address leaving the existing primary address intact:

$user = Get-Mailbox username
$user.emailddresses+="user@domain.com"
Set-Mailbox $user -EmailAddresses $user.emailaddresses

You can simply do the following, the new PrimarySmtpAddress sets the email as the primary address (you may have to disable EmailAddressPolicyEnabled):

Get-Mailbox user1 | Set-Mailbox -PrimarySmtpAddress user1@domain.com -EmailAddressPolicyEnabled $false

Thanks Mike, That worked.

To add here for others...

We can find the index of the values in the this array as below.

$mb.emailaddresses.Indexof("value in ProxyAddressString")

Correct me if i am wrong here.
