Last year, I had a project that involved migrating a large customer from Office 365 Dedicated to Office 365 GCC (multi-tenant). While Exchange hybrid moves were possible for the mailboxes, we were unable to perform the necessary hybrid migration configuration for Lync to migrate users. While Lync was configured and available, not many end users actively used it.

To that end, we decided to just leave them as-is in the legacy environment and light up new accounts in Office 365. We configured the appropriate Skype DNS entries (like _lyncdiscover, etc) and were off to the races.

It worked fine for people who had never used Lync or Skype before, but users who had previously logged into the old Lync environment kept trying to contact the previous environment, despite no DNS records pointing there. The problem lies in the way Lync and Skype cache logon data.

I’m not going to write routing statements or firewall rules for you (in this post–I’ve definitely got some things cooking since I lived a previous life as a Cisco guy), but I will give you a quick and dirty script to wipe out the cache per workstation. You can add it to a computer start-up script to and execute once upon user login (maybe set a reg key in HKLM so you don’t keep re-running it).

Of course, since this is a script that deletes things, it goes without saying to test this in your own environment.

This page describes how to clear Windows Credential Manager to remove stored Skype for Business login credentials

Windows Credential Manager is a service on Windows 7, 8, and 10 that stores login credentials to allow Skype for Business and other services to login automatically at start up. This can sometimes cause problems logging in, one of the first steps in troubleshooting failed logins in Windows should be removing those stored credentials from the vault.

To do that you first need to make sure you have fully exited the Skype for Business client.
Then go to the Start menu and find the control panel (settings). In the control panel search for Credential Manager and open it.
Under Windows Credentials > Generic Credentials, there should be an entry that starts 'Microsoft_OC1:uri=' and 'MicrosoftOffice16...'

These are the stored Skype for Business credentials.

Click the downward arrow to expand the credential and then at the bottom of the credential select Remove.

Make sure to remove ALL the credentials starting 'Microsoft_OC1:uri=' and 'MicrosoftOffice16...' as any of them could be the one causing the problem.

After this try to log in to Skype for Business again.
