Recently I encountered the following issue when trying to publish a Skype for Business 2019 topology. Thankfully, this is the first or maybe the last time I have seen this issue.
Error Message
Topology Builder encountered an issue and cannot publish this topology.
Topology Builder has encountered an unexecpted error from Skype for Business Server 2019 Management Shell.
Error Details: Get-CsManagementStoreLocation did not return a valid connection
To resolve this issue launch Skype for Business Management Shell and run the following cmdlet;
Remove-CSConfigurationStoreLocation
You will now be able to successfully publish your Skype for Business topology without receiving the error you encountered earlier.
While running the Exchange Hybrod Configuration Wizard I ran in the following issue;
HCW8078 – Migration Endpoint could not be created Microsoft.Exchange.Migration.MigrationServerConnectionFailedException The connection to the server ‘http://mail.domain.com’ could not be complete
This issue is a known issue to Microsoft and the resolution is the good old “Have you tried turning it off and on?”
The resolution was to Disable MRSProxyEnabled, this can be easily completed for all servers using;
This script will need to repeat this process for all your servers where MRSProxy is being used. Invoke-Command -ComputerName Server1 -ScriptBlock {iisreset /restart}
Once you have completed the below steps you will be able to successful rerun the Hybrid Configuration Wizard without any errors
One of the gotchas you may encounter when migrating mailboxes to Exchange Online is none registered Accepted Domains in Exchange Online. For example you may encounter the below error;
ERROR: Migration Permanent Exception: You can’t use the domain because it’s not an accepted domain for your organization –> You can’t use the domain because it’s not an accepted domain for your organization.
This maybe due to an email alias on a particular mailbox or all your organisation mailboxes due to an Email Address Policy. When migration to Exchange Online on you need to register all your accepted domains and remove any that may cause you the above issue.
In my case, I had domain.com registered with EXO but not extension.domain.com, as the alias was a legacy address you could be removed from the mailbox either using the Exchange Management Console or my favourite utility PowerShell.
Please ensure that Azure Active Directory has synchronize this change to your mailbox

Testing – DLP for Micorsoft Teams
So like with all things Microsoft, we have to wait for replication to take place before we can really start testing DLP. Please dont expect your change to work straight away as its needs to work its way through the big Microsoft cloud.
Email Notification that NINO Number has been shared using Microsoft TeamsWarning Message to the User that sent the NINO Number Email Notification that NINO Number detected in Exchange
So its safe to say DLP is now working within my tenant.
When working with Exchange there may be a requirement to create a PowerShell script using PowerShell ISE. Even if you run ISE on a Exchange Server you are unable to get the Exchange cmdlet in ISE, so the workaround for this is to use the following command;
If you are trying to add the Exchange cmdlets to your client machine you will need to Install the Exchange Management Tools from the Exchange installation media
The command to import the Exchange modules is different for each version – please use the appropriate command below:
