Enjoy millions of the latest android apps, games, music. Lync Server 2010 is not supported instead we recommend customers continue to use the Lync for Mac 2011 client. Visit the Known Issues and FAQ pages for more information. Visit the Skype for Business Client Comparison Tables for side by side feature comparisons for Lync, Skype for Business and Skype for Business Server.Just one month after releasing a technical preview, Microsoft has announced the availability of the new Skype for Business client and Skype for Business Online, its planned replacement for the Lync communication software.Set up Skype for Business Online Skype for Business. Skype is a video, audio, and chat app by Microsoft. The app is available on Mac and PC and on iPhone and.I have been invited to a Lync/Skype for business meeting and I can not join it from my Mac for a number of reasons.
![]() Lync For Business Series Aimed ToCan scale further by adding more Front end servers to the pool But this has changed with Lync 2013 server architecture, where users services were moved from the backend databases to the Lync Front end servers.What I see best advantages of this approach are: I saw a scary number of Lync 2013 deployments in the last 8 months where the Lync is deployed using an Enterprise pool with only two front end servers, even I saw a couple that have an Enterprise pool with only one front end server, yes you read that right, only one front end server.So I decided to write another post of my “Simple Understanding” article series aimed to explain the Lync 2013 server architecture, how it utilize windows fabric for high availability and why you should not deploy a 2 nodes Enterprise Edition pool, I’ll try to use small words and simple explanations as I can.I’m planning also to use this article as a guide to share with customers which have an existing Lync deployment or considering Lync to help them in their decisions.In previous version of Lync 2010, user services was provided by the Backend database, and that’s why when the SQL backend goes down, the Lync clients goes into “Limited Functionalities” status. As the name suggests, Skype for Business has the look and feel of Skype, with things like IM, voice and video calls, and online meetings.From this point on, it is the primary front end responsibility to write all new user’s information to the SQL backend (like user create a new conference or add a new user) as well as replicate them to both primary backup and secondary backup servers. Once front end server finish collecting user’s information from the SQL backend, it replicate user’s information to both the primary backup and backup servers. First time front end service “Starting”, the front end server connect to the SQL backend and collect the “User’s Information” of all users that it is responsible for. In my lab I have only one user enabled for Lync, so when checking Routing Groups in the RTC database I see only one Routing Group (does not matter which SQL you’re checking because Lync is not depending on the backend anymore)Each Routing Group has a FrontEndID associated to it, this is the Primary Front end server for that Routing Group (User), in my lab it has the value “3”You can “decrypt” this value by checking the FrontEndID table, this table include the front end nodes in the pool (run the following query)So as you see, my only Routing Group (user) has FrontEndID server “3” which is LYFE02, that’s the same result we got using Get-CsUserPoolInfo command line up in this article.SIDE NOTE: the Routing Group Id is written to the Active Directory user account under the attribute msRTCSIP-UserRoutingGroupId in reverse orderI would summarize how windows fabric works in 4 simple steps The number of Routing Groups increases when you add more users to the front end pool, you find Routing Groups in the RTC database inside the RoutingGroupAssignment table (use the following query):FROM. Primary front end= LYFE02 (keep it in mind)As agreed so far each user have a primary front end, this info is written in the SQL backend databases with a little tinny difference, when it comes to SQL backend each Lync user is a Routing group.![]() As mentioned before Microsoft recommend using 3 front ends when deploying Enterprise pool, if you cannot deploy 3 front ends, then use two standard edition pools with pool pairing User information will not be affected, because the primary Front end was always replicating the user information to the primary-backup and secondary-backup servers.If I run get-csuserpoolinfo on the same user now I can see that the primary back up front end server got promoted to be the primary front end server, and the secondary backup front end became the primary backup front end.So now that you understand how Lync utilize Windows Fabric and how does it work, give you some notes that you keep in mind the primary storage services will be assigned to the front end (I noticed it is always the secondary backup front end, but I’m not sure if this is the case always ) – Lync Storage Services Event ID 32033 My passport for mac set passwordto confirm that, if you check the Windows Fabric “ClusterManifest.current” file, and compared it to the one mentioned above in this article (from 3 Front Ends Pool) you will notice addition section called “Votes”, where Windows Fabric uses the SQL server in the Votes to maintain Pool-Level quorum. in case of a two servers in Enterprise pool, Lync uses the SQL backend server as the witness server to maintain the Pool-level quorum, in case you have Mirrored SQL, Lync will use the primary SQL server in the Mirror as a witness server LS User Services Event ID 32189: Pool Fabric will disconnect the users (close routing group connections)LS User Services Event ID 32173: Lync Front ends server will start shutting down after 5 minutes LS User Services Event ID 32163: the Pool manager will disconnect from the Fabric pool manager due to loss of quorum Lync 2013 server still need SQL backend, and if for any reason the SQL backend is unavailable, Lync Front Ends goes into survivable mode after 30 minutes.In case minimum number of Front ends in a pool is not metIn case number of front ends in a pool is not met, the front end services start shutdown after 5 minutes, in a nutshell the following happens According to TechNet, following table show the total number of Front ends needed to be running in a pool to maintain the Pool-Level quorum if for any reason the SQL backend is unavailable, and the minimum number of Front Ends need to be running in the pool is not met, Front End services shut down after 5 minutes (check table above). if the SQL backend not brought back online in 30 minutes, Lync Front Ends goes into survivable mode. the Lync clients goes into “Limited functionalities” mode same like what happen in Lync 2010 server.
