Hi,

 

A few years ago we used Hosted Skype for Business with PSTN connectivity. Recently we left that host and now use a new vendor who set us up with Teams with their PBX system instead. Everything works fine except certain users that were on SfB have their extensions locked (see screenshot).

 

Our new vendor said only the old vendor could fix that. When we contacted the old vendor they said this:

 <START SNIP>

We have made Azure AD Sync with our On-premises long-time ago,

It seems the users have synced the extensions that time, after we disabled the AD connect Sync, the users on office365 have kept the extensions and have been locked,

To resolve this:

  1. You have to enable Azure AD Connect Sync from your side
  2. Give us an admin access to your Office365.
  3. We are going to remove all extensions on our side (On-premises)
  4. We are going to Activate the AD connect Sync. (the users will be synced to Azure with no Extensions)
  5. After that the users will be with no extension assigned to them on your Office365, then you have to Disable Azure AD connect Sync
  6. Then we will Reassign the Extensions again to all users in our side

<END SNIP>

 

We are very hesitant to give our old vendor admin access for several reasons.

 

Is there anyway we can get these extensions unlocked ourselves without involving our old SfB host?

 

Thanks,

Phil
