Migration from 2015 to SFB 2019 with SQL FCI

Ralf Bopp — Thu, 31 Jul 2025 13:40:36 GMT

Hi,

Customer have a 2015 setup with SQL Mirroring.

All working fine so far.

Now we Setup a WFCI with CSV and an SQL FCI. The installation ran smooth and we can access the SQL FCI Name via SQL Management Studio.

Also test with port 1433 and 1434 are working. Permissions are checked and we have sa rights on the Databases.

After Setting up the 2019 environment in the Topology the Databases for the 2019 environment cannot be installed on the SQL FCI.

Always the same error, trying with Install-CSDatabse or with the TB.

User also have sa rights.

After 10minutes this error occured :

We tried nearly everything. But SQL FCI with Skype for Business seems not so common.

Thank you for Help

Skype Meeting App issue

BHConsult — Mon, 18 Mar 2024 18:49:05 GMT

Having an issue with invitees joining Skype For Business 2019 meetings hosted on on-premises.

Using the join meeting URL externally brings up a blank screen with the thinking wheel of dots.

Using the same URL on the same browser with ?SL= appended to it brings up the Guest sign in screen.

Skype for Business Server 2019 IM Integration with Exchange Server 2019

joestar22 — Mon, 26 Feb 2024 14:57:12 GMT

I am having difficulty getting the IM/Presence integration to work between my on-prem Skype for Business 2019 Server and my Exchange 2019 Server.

I believe I am having a certificate trust issue. On important note is that my internal domain is domain.local and the external is domain.com. So, my public wildcard certificate is for *.domain.com.

When I look at the certificates on the exchange server, there is another certificate that is assigned to IIS issued by the local certificate authority which protects domain.local. I have tried a variety of combinations using either the local certificate with the domain.local name of the servers as well as the public wildcard certificate thumbprint and the dns a record with domain.com that points to each server. None of these combinations seem to work for me.

I have run these commands on the SfB Server:

New-CsTrustedApplicationPool -Identity exchangeserver.domain.local -Registrar sfbserver.domainlocal -Site "My Site" -RequiresReplication $False

New-CsTrustedApplication -ApplicationId OutlookWebApp -TrustedApplicationPoolFqdn exchangeserver.domain.local -Port 5199

I have run these commands on the Exchange Server:

New-SettingOverride -Name "IM Override" -Component OwaServer -Section IMSettings -Parameters @("IMServerName=sfbserver.domain.local","IMCertificateThumbprint=mycertificatethumbprint") -Reason "Configure IM"

Get-ExchangeDiagnosticInfo -Server EXCHANGESERVER -Process Microsoft.Exchange.Directory.TopologyService -Component VariantConfiguration -Argument Refresh

Restart-WebAppPool MSExchangeOWAAppPool

Get-OwaMailboxPolicy | Set-OwaMailboxPolicy -InstantMessagingEnabled $True -InstantMessagingType OCS

When I check the instant messaging logs on the Exchange Server I see the following:

If I try to use the domain.com name and the wildcard certificate I get this error:

On MACP, (400 : HTTP/1.1 400 Bad Request) when enabling a user.

Sistemas_depo — Fri, 26 Jan 2024 09:28:40 GMT

Hello everyone!

My problem is:

When enabling a user on the new MACP, IF the user has configured an email address gives the subjet error.

If the user doesn't have configured email address, user is enabled but not without a problem.

Viewing trough developer mode on the browser, the error lies in:

https://<sfbs-fe-pool-fqdn>/OcsPsws/Service.svc//$batch

The payload of the $batch:

The only difference is that on the failing payload i see:

And on the working payload:

PATCH /OcsPsws/Service.svc/CsAdUser('<BLABLABLA>')

Sounds like a bug? Configuration problem??

Edit: I forgot to mention the environment - SfBS 2019, patched to October 2023 level.

Three Win servers 2019 as front-ends, two win server 2019 as Edges.

Applied, as patch requested, the prerequisites without errors.

Skype for Business 2019 Edge Server with other RD Gateway

joestar22 — Thu, 25 Jan 2024 17:56:08 GMT

I have a Skype for Business 2019 Standard Edition Server currently running without the Edge Transport server. I'd like to add remote access but would prefer not to have to deploy another server specifically dedicated to this. Does anyone know (or has anyone tried) installing Skype for Business 2019 Edge Server on the same machine as a terminal server running RD Gateway and RD Web Apps? Or, is there any other server this could run on without interfering? I have a server running Office Online Server (OOS) and I have another running Sharepoint, one running Exchange 2019, one running Skype for Business 2019 frontend and then the one running RD Gateway and RD Web Apps as a terminal server. Thanks!

Decommission Skype 2015 On-Prem servers

p0shkar — Tue, 23 Jan 2024 12:14:26 GMT

I want to decommission our Skype On-Prem (2015) servers and cleanup AD from the RTC delegations and groups (RTC* and CS*). I've been following the guide: https://learn.microsoft.com/en-us/skypeforbusiness/hybrid/decommission-remove-on-prem

However, when doing step 1 of "Prepare to remove the Skype for Business deployment" and run the commands, the command Get-CsAudioTestServiceApplication returns an object. In step 2 there is no corresponding Remove-cmdlet, so we tried disabling it with the Set-cmdlet.

Moving on to "Remove your on-premises Skype for Business deployment", when getting to step 3 I run "Publish-CsTopology -FinalizeUninstall" but gets the following error.

Publish-CsTopology : Command execution failed: Cannot publish topology changes. Users or contacts are still homed on a pool that would be deleted. Move or remove the users or contacts before continuing. At line:1 char:1 + Publish-CsTopology -FinalizeUninstall + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [Publish-CsTopology], Inva lidOperationException + FullyQualifiedErrorId : ProcessingFailed,Microsoft.Rtc.Management.Deploy ment.PublishTopologyCmdlet

Running the command generates a html file with the result, where the same error can be found and the following suggestion:

"UserPoolInUseResolution: Consult your Skype for Business Server documentation to learn how to move or disable objects still homed on the pool. To find those objects, execute the following cmdLets: Get-CsUser, Get-CsExUmContact, Get-CsCommonAreaPhone, Get-CsAnalogDevice, Get-CsRgsWorkflow, Get-CsDialInConferencingAccessNumber, Get-CsAudioTestServiceApplication, Get-CsTrustedApplicationEndpoint, Get-CsPersistentChatEndpoint."

So I'm guessing we need to get rid of that Audio Test Service Application, anyone got any ideas how to do that? I can't find anything for it in the GUI either.

The main objective is to clean up any remnents in AD, the entire Skype environment will be removed and all servers decommissioned. I'm guessing that the Disable-CsAdDomain and Disable-CsAdForest cmdlets does this somewhat. Is the above steps a requirement to be able to run these cmdlets, or would this be a viable option?

Publishing new topology for additional SIP trunk.... Downtime?

Martin-17 — Mon, 04 Sep 2023 10:30:40 GMT

Just looking for a quick bit of advice here please. We have the urgent need for a new SIP trunk on an existing (working) S4B 2019 Standard deployment.

From editing the topology to publishing this, will this cause any downtime to the existing Skype deployment due to just adding an additional medial gateway and SIP trunk? The rest of the configuration is staying the same.

Also are there any other gotchas to be aware of?

Thanks

In place OS upgrade of Skype Edge server

MikeM1220 — Mon, 07 Aug 2023 20:28:38 GMT

Is it possible to do an in place OS upgrade of an Edge server? Migrating from 2015 to 2019. Our Edge is 2015 which I know will work with the 2019 Pool, but the OS on the Edge is 2012 R2 and needs to be upgraded. We were going to decommission our Edge because we switched to Zoom and just use SFB for internal needs, but I think mobile clients need the Edge server to join meetings. If I am wrong on this, and hope I am, then never mind.

Skype to Teams Migration Issues (Skype Server Standard 2019 - On Prem 7.0.2046.244)

Martin-17 — Wed, 02 Aug 2023 08:07:19 GMT

Hi all,

Just looking for some advice here for a Skype on-prem to Teams migration. I'll try keep this as short as possible but please find some info below:

Background

Customer A is moving from using Skype 2019 on prem with Anywhere365 core (also on-prem) over to Teams only with Anywhere365 dialogue cloud. We are at the stage where we are almost ready to switch over, however have uncovered some issues with the migration process to rehome the users. From reading it looks like Microsoft now require you to be on a minimum version of 2019 on-prem to be able to migrate the users over to Teams:

As of July 31, 2022, to move users between an on-premises deployment and the cloud, you must be using the following minimum versions of either Skype for Business Server or Lync Server:

On-premises product Required minimum version Required minimum build

Skype for Business Server 2019	CU6	7.0.2046.385
Skype for Business Server 2015	CU12	6.0.9319.619
Lync Server 2013	CU10 with Hotfix 7	5.0.8308.1182

The problem we have, I believe is basically down to the fact we have inheritied a Anywere365 and Skype installation which has not been kept up to date and is stopping us from progressing any further. Customer A is 24/7 so we are trying to find the best way around this without having to upgrade the Skype environment, Anywhere365 core (this is needed to work with newer versions of Skype) to then just bin these servers off after the migration. Its going to cause unecessary disruption and potential wasted engineer time.

Question

My question is, has anyone been in the same position with migrating skype for business 2019 on prem over to Teams and is there any workaround without upgrading the kit and successfully using hybrid connectivity with the migration commands?

Further Information

I have done some testing with the current kit, all hybrid connectivity is configured I believe the migration failure is now just down to the skype version.
I have tested a potential workaround, which involves deleting a user from on prem Skype (not removing their AD user) so that the majority of the skype flags against a user get cleared, line uri, enterprise voice config etc.. and allowed this to sync back to 365. I tried then applying the direct routing configuration on Teams only to still get an error that the user is using Skype on prem and to migrate them. I then went into on-prem AD and cleared the remaining msRTCSIP attribute which was the PrimaryHomeServer from SRV: to <not set>. When I have checked this morning, after the sync overnight to 365, the user is now showing with the correct attributes such as:
- HostingProvider : sipfed.online.lync.com
- AccountType : User
- TeamsUpgradeEffectiveMode : TeamsOnly
- TeamsUpgradeNotificationsEnabled : False
- TeamsUpgradeOverridePolicy :
- TeamsUpgradePolicy : UpgradeToTeamsThis would suggest to me that I can now correctly configure this user for direct routing which I am going to test this morning.

Its a bit of a dirty workaround however, it could be the preferred option depending on the upgrade possibilities and downtime. Has anyone done this before and would this cause issues in the future if the microsoft 'official' process isnt followed?

Any help or advice is appriciated!

Thanks

Skype 2019 Migration away from Skype 2015

masorrell — Thu, 30 Mar 2023 20:03:41 GMT

On my first 2019 FE, I am trying to download the topology and it fails. I am not sure what I am missing. I haven't actually given a DB instance or anything yet so how does it know where to look exactly for the topology? Is it a rights issue or a lookup issue? I can't figure it out...thus, I am here.. 🙂

Skype 2019 MACP Stopped Working - User has insufficient permissions

jafnva — Tue, 28 Mar 2023 16:22:13 GMT

We have been using the Skyp 2019 MACP for some time without any issues. When we first set it up, we had the error message "User has insufficient permissions" but were able to resolve it by installing OData and running bootstrapper.exe. I'm not sure what is causing it this time, I ran the bootstrapper.exe again but that did not change anything.

Does anyone know what could be causing this issue, or where we should look (our Skype Admin has moved on and we haven't found a replacement).

Thanks!

Teams Auto Attendant, Hybrid Application Endpoint, On-Prem URI

_wampa__stampa — Wed, 18 Jan 2023 17:44:58 GMT

Hello,

I'm not sure if this would be better suited here or in one of the Teams communities, but it seems to be a specific use case for SfB server.

We are trying to retire the old Exchange 2016 and migrate the Auto Attendants but have hit a road-block.

We have a few legacy UCMA applications utilizing trusted application endpoints. We're trying to get them migrated to Teams bots, but the timing likely isn't going to work out. In the meantime, we are unable to route calls to these on-prem application endpoint accounts from the Teams AA.

The Teams AA are using resource accounts created with New-CsHybridApplicationEndpoint, but it seems that the on-prem TrustedApplicationEndpoint objects aren't synchronized to M365 as they appear to be in one of the hidden OUs only accessible in ADSIEdit, or at the very least their URI is not visible to Teams.

Has anyone ran into this oddly specific problem and know of any work around? Relevant thread: https://techcommunity.microsoft.com/t5/microsoft-teams/trusted-application-endpoints-in-teams/m-p/806077

Thanks!

Error : User has insufficient permissions When logging onto MACP

Rmorrissey — Wed, 06 Jul 2022 19:59:16 GMT

Hi,

We are trying to move to using the new MACP in order to remove Silverlight from our Skpe servers.

When trying to log on as a member of the CS Administrators group to our enterprise site (https://sfb_ent.corp.ourdomain.com/macp/login) we get an

Error : User has insufficient permissions.

The user is a member of the CS Administrators group and SIP is enabled.

When we try to log onto a SFB Standard server we just get the error box, but instead of an error message it just displays the letter E.

Any suggestions on how to troubleshoot this?

Thanks
