Lync/SfB – Simultaneous ringing not working

Hi all,

New day, new challenge !

We faced an issue where users who use/used the Skype for Business mobile client were not able to get simultaneous ringing working…

Even they disconnect and uninstall the application, simultaneous ringing was no more working for their mobile device set in AD but it was working with another number.

Then I launched the lync debug tool and saw that it was trying to reach the sip address push@push.lync.com (the phone number to reach was on an iPhone)

So I tried to test the push notification with this command on the front-end server :

Test-CsMcxPushNotification -AccessEdgeFqdn EdgeServerFQDN

So I followed the article to configure push notifications : https://technet.microsoft.com/en-us/library/hh690047%28v=ocs.15%29.aspx?f=255&MSPPError=-2147217396

Then simultaneous ringing start to work again for those users who were using the mobile app.

Domino/Exchange – Perform offline migration nsf to pst

Hi all,

If you cannot or don’t want to have a direct connection between your “old” domino servers and your Microsoft Exchange servers, then you can use Quest Notes Migrator for Exchange to convert nsf files to pst. Here is how to do it :

  1. Export names.nsf (NAB) from domino server and copy it on NME server
  2. Launch the NME program and perform the SQL configuration and logs folder path then close NME
  3. nme1
  4. nme2
  5. In ini conf file, add the following parameters:

[General]

PABDest=PST

ServerMailDest=PST

ArchiveDest=PST

[Notes]

Offline=1

[Exchange]

ArchiveResolveAttendees=0

ServerMailResolveAttendees=0

TargetType=2013

  1. With SQL management studio, create the domino server from where the names.nsf is coming with the command below:

INSERT INTO [NME40DB].[dbo].[T_NMEServers] (NMEServerGUID,DisplayName,ServerType,ServerName,HostName) values (‘12345678-1234-1234-1234-123456789123′,’DominoServerName‘,1,’DominoServerName‘,’DominoServerName‘)

For example :

INSERT INTO [NME40DB].[dbo].[T_NMEServers] (NMEServerGUID,DisplayName,ServerType,ServerName,HostName) values (‘12345678-1234-1234-1234-123456789123′,’CHMAMA01′,1,’CHMAMA01′,’CHMAMA01’)

  1. Launch again NME and perform the “Discover Notes Information” by adding the “names.nsf” you got from step 1 this will help NME to translate Domino user names into Exchange user names
  2. nme3 nme4 nme5
  3. Then you can start your migrations/conversions by creating the collection of mailboxes you want to migrate and then launch the locate Notes datastore to define where to search the nsf files :
  4. nme6 nme7
  5. Finally you can launch the migration with the final step “Migrate user data”

SFB – Dial-In number displayed twice for new Skype meeting

Hi all,

On a fresh install of Skype for Business, I created one and only one dial-in number but this one wear appearing twice when creating a “New Skype meeting” from Outlook.

We discover that this was the case only when using Outlook 2010 or 2013 with the Skype for Business client 2016.

This was not the case when using Outlook 2016 or OWA.

The only workaround I found was to create a second dial-in number for a different language (One for English and one for French) then both numbers were appearing and no duplicates.

FYI, I was running Skype for Business Server 2015 with CU4.

Hope it will save you time troubleshooting.

EXCHANGE – X-OWA-Error: Microsoft.Exchange.Data.Storage.StorageTransientException

Hello,

New day, new problem !

Some users for an unknown were not able to connect to OWA and Outlook suddenly, I never had time to find why unfortunately…

The error in OWA was : X-OWA-Error: Microsoft.Exchange.Data.Storage.StorageTransientExceptiontransienterrorexchange2013

What I did to correct the issue was simply to modify one digit  of the legacyExchangeDN, the last part which is random.

/o=blabla/ou=exchange administrative group (fydibohf24spdlt)/cn=recipients/cn=ef520295b5ab4cc3949fd9e06b7b6285-dbrooks

to

/o=blabla/ou=exchange administrative group (fydibohf24spdlt)/cn=recipients/cn=ef520295b5ab4cc3949fd9e06b7b6287-dbrooks

Hop this will save time in case it happens to you

O365 – Create Mail User from AADConnect synced user

Hello all,
A few days ago, I had to make a user in a local AD appearing as a contact in O365 address book.
The local AD was not having a local Exchange so I couldn’t use the ECP to populate the right attribute…
Here are the required attribute to fill in the local AD user to make it appear in O365 address book as a contact (mail user):
mail = externalemail@domain.com
mailNickName = internal.username (should be the same value as samAccountName)
targetAddress = SMTP:externalemail@domain.com
proxyAddresses = SMTP:externalemail@domain.com
Hope this will save time to you

Skype for Business – Unable to share Poll, whiteboard and Powerpoint presentation

Hello all,

I had an issue recently where one user was not able to share a poll, a whiteboard and a Powerpoint presentation.

The infrastructure was Skype for Business 2015 Server Standard with last CU (June 2016) and the clients were all having Skype for Business version 16.0.4432.1000.

But for only user this was not working and when he tried on another computer then it was working so it was due to his computer…

Indeed the KB3118288 was missing and as soon as we installed it, everything started to work on this computer.

Installing the KB does not change the client version and stay 16.0.4432.1000

Hop this will help some of you !

LYNC/SKYPE FOR BUSINESS – Fail to escalate IM conversation to Microsoft Whiteboard sharing or Microsoft PowerPoint sharing session with a federated user

Hi Guys,

I have go a lot of things to say this week !

I had a new issue corrected thanks to a great MS Engineer ! We were having an error when trying to share a PowerPoint file with a federated user, this one was going to the lobby for a minute and then it failed. See below :

IssuePPTFederation

Again thanks to this great MS Engineer, we found that it was due to this known issue : https://support.microsoft.com/en-us/kb/3051968 and indeed we were using the Lync 2013 client (or Skype for Business 2015 which is Lync 2013 with SFB UI)

So after launching the following commands :

Get-CsConferencingPolicy | Set-csconferencingpolicy -AllowAnonymousParticipantsInMeetings $true -AllowFederatedParticipantJoinAsSameEnterprise $true

Set-CsAccessEdgeConfiguration -AllowAnonymousUsers $true

All was working fine !

Enjoy !!!

LYNC/SKYPE FOR BUSINESS – Desktop sharing not working with federated user

Hello folks,

It has been a while I haven’t write something ! Anyway, I had an issue some weeks ago on a fresh Skype for Business environment. We were having a “Network error” when trying to share a desktop in a peer to peer context with a federated user (Lync 2013 and Skype for Business 2015).

It was working between two internal users, between an internal and a remote user and between two remote user.

After looking at the firewall logs when performing test, we found that the federated user was trying to access the Audio/Video on port 5*****… You know the range 50000-59999 that should only be used for RTP traffic with OCS 2007 federated users ! So those ports are also used with Lync 2013 and Skype for Business federated users for RTP traffic.

Cheers

LYNC/SKYPE FOR BUSINESS – Powerpoint/Whiteboard/Poll not working

Hello all,

It has been a long time since I have not write a new post but that day I got a new issue.

On a fresh new Skype for Business environment, I had an issue with the Powerpoint sharing no more working (was working some days ago…).

So I started to check all my config and check what changes I have done since it is no more working, I haven’t found something related to this issue.

So I used fiddler to check what is happening on the client side and see that the client never tried to reach the Office Web App server so I understood that the error was between the Lync/S4B client and the front-end.

Then I saw that article -> http://tomtalks.uk/2016/05/microsoft-net-security-update-ms16-065-breaks-lync-server-20102013-skype-business-server-conferencing/#comment-100590

And remember that the admin installed some updates in the last days.

So I followed the MS article -> https://support.microsoft.com/en-us/kb/3165438

In my case, the key “HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework\v4.0.30319\System.Net.ServicePointManager.SchSendAuxRecord” wasn’t existing on my front-end so I created it and created the DWORD value. I restarted the RCTDATAMCU and after restarting my S4B client, the powerpoint sharing worked again !!!!!

I would like to thanks Tom for his help.

Bye
