Trying to clear out an old sip address that was left around from an OCS setup we had. I've identified the users who have the SIP address with this:

 get-aduser -Properties * -Filter * | where ProxyAddresses -like "sip:*domain.local" | select samaccountname

However I can't seem to clear the SIP. For example:

Get-ADuser proxytest -Properties proxyAddresses | Set-ADUser -remove @{proxyaddresses="sip:*domain.local"}

Also tried:

Get-ADuser proxytest -Properties proxyAddresses | Set-ADUser -remove @{proxyaddresses="sip:*"}

It never clears sip address.

I tried that and it doesn't work. The sip is not always position 0.

Also for whatever reason this doesn't work either. I can set values to other attributes, but for whatever reason you can't tab out proxyaddresses like you can office,phone or manager etc

Get-ADuser proxytest -Properties proxyAddresses | Set-ADUser -ProxyAddresses @{Remove="sip:*"}

Our email accounts are in O365 so I can't use the get-mailbox cmdlets, I'm substituting with get-aduser...

$user = get-aduser proxytest -properties proxyaddresses
$proxy = $User.proxyaddresses | sls "sip"

returns this error:
Method invocation failed because [Microsoft.ActiveDirectory.Management.ADUser] does not contain a method named 'remove'.

The where $_.prefixstring in the code he used as an example returns nothing which is why I used sls to get the sip.

$user = get-aduser proxytest -properties proxyaddresses
$proxies = $user.proxyaddresses
$sip = $proxies | sls "sip"
set-aduser $user -Remove @{proxyaddresses=$sip}

Similar to what you have but try this

Get-ADUser proxytest -prop proxyaddresses | % {
$pr = $_.proxyaddresses -like "SIP*"
Set-ADUser $_ -Remove @{proxyaddresses=$pr}

It should remove all SIP addresses for the user

Thank you so much, that worked!!

I never thought clearing this would be so difficult.

Glad that worked 🙂
