IOS Lync client can't join meetings

I have an iPhone user who was able to join Lync meetings when he was at home and at his office. He recently moved to a new office, and now every time he tries to join a meeting, Lync 2010 says "Can't connect to exchange web server. You can try again
later." I can see him pop into the meeting and immediately disappear again.
He is signed into Lync and into Exchange or he wouldn't be able to see the meeting from the Lync client. The problem is only with
joining the meeting. So the server addresses, username, etc., should be correct.
Is this a problem with cell service (He has 2 bars of 4G at his new location) or is something else going on?

Please check if the problem exists with other Lync mobile devices and other Lync accounts.
If the problem exists with all users in the new office, please check the Outlook Anywhere rule is there for the new office.
For further troubleshooting, enable logging in Lync Mobile client on the iPad and check the logs for any issues connecting to Exchange Autodiscover URL or EWS URL.

External Lync clients can't join meetings - get kicked out with "You have left the call"

My users connecting remotely (ie. from home) from their Lync clients installed on their PC are unable to join any meetings. It tries to connect, but then gives the status "You have left the call."
Internally (ie. in the office) it works fine. Additionally, the Lync Web App clients also works fine, internally and externally.
Some details on my enviroment:
Edge - Lync 2013
Front End Pools - one 2010 Enterprise (albeit one server), one 2013 Enterprise (two servers)
A standalone Lync 2010 A/V server exists as well.
Meet and dialup records internally point to 2010 pool. Externally, they point to 2013 access edge.
SRV records on external DNS are _sip._tls 443 and _sipfederationtls._tcp 5061, both point to access edge.
SRV records on internal DNS are _sipinternaltls._tcp 5061 to sip (which is an "A" record with IP for 2013 FE pool), and _sip._tls 5061 to access (which is an "A" record with the internal IP of the edge server).
Any thoughts on how to troubleshoot this would be most appreciated. Thanks.

Can external Lync user make an audio call to an
external user?
Your problem is mostly related with Lync Edge Server.
Check Lync Server Audio/Video Edge service is started.
Please use Remote Connectivity Analyzer to perform Audio/Video server connectivity test:
https://testconnectivity.microsoft.com/
Please check if you can find error in event log on Lync Edge Server.
Check the required ports are opened, for details, check

Lync 2010 - Can't join to a meeting with Web App, client ok

1. User creates an Online Meeting
2. Everyone can join to it with Lync client installed
3. When trying to join without Lync client (or forcing it with "?sl=") an error is received:
The meeting link you are using to join is not valid. Please check the link and try again.
I've tried it with the lates Chrome and IE versions.
Any ideas?
EDIT: Seems to work with older IE browsers...

Hi,
From your description above, it is the issue of the wrong suffix "?sl=". The correct suffix is "?sl=1". Please test if with the correct suffix and check if the issue happen again or not.

Lion Server: iOS 5 clients can't connect to Address Card Server

I have set up shared accounts on the server for Calendar and Address Book (family) sharing. Although I can add and use the Address Book shared account on OS X Lion clients, I can't get this to work on iOS 5 clients (iPhone nor iPad). I keep on getting "CardDAV account verification failed".
Calendar sharing works just fine on both OS X and iOS5 clients
Let me briefly describe my setup and observations:
Server:
Running Lion Server 10.7.2 on Mac Mini (server)
Using SSL connections with keys generated during set-up of the server
Portforwarding in router (ao) for 8008 and 8843 (iCal and Address Book)
Created shared accounts on server for Calendar ("sharedcalendar") and Address Book ("sharedcontacts")
In the DNS server I created services in my primary zone for "_caldavs._tcp." and "_carddavs._tcp." both on port 8443
OS X Client (Calendar)
Created additional CalDAV account in preferences (user "sharedcalendar")
Left the server settings untouched (server path, port "auto" and using SSL but not Kerberos)
Created in "sharedcalendar" different calendars and reminder lists for the family members which each can access from their OS X client
This account is now set-up through Profile Manager (tried this with Address Book as well but didn't make any difference)
iOS 5 Client (Calendar)
Once tested on standalone and got this working I'm now using the Profile Manager to push the definition of the shared account to all clients
Hostname with port 8443 (default)
Left Principal URL blank since it was optional
User "shared calendar" with the appropriate password
Ticked "Use SSL"
OS X client (Address Book)
Created additional CardDAV account in preferences (user "sharedcontacts").
Left the server settings untouched (port 443 using SSL)
iOS 5 client (Address Book)
In the settings add a CardDAV account (server, user "sharedcontacts", password, description).
First error message "Cannot connect Using SSL. Do you want to try setting up the account without SSL?". When I press continue I get the error "CardDAV account verification failed"
If I then save the account details still and edit the account I can access the "advanced settings". When I change to SSL I have tried port 0 (default value), 8443 (the one that's listed in the documentation) and 8843 (which is used by default if you try to set up the
account in Profile Manager). All to no avail, including Profile Manager
Observations:
Lion Server app nicely lists both Calendar and Address Book Server as active (plus Profile Manager, File Server, Web server and Wiki server)
When I access my server home page, Calendar is listed in addition to other services (Mail | Calendar | Change Password | Profile Manager) but not Address Book. Is this normal behaviour? i.e. can't Address Book entries be changed through a web interface?
Address Book on OS X client uses 443 for SSL but does not require me to define port 8443 for secure iCal or Address Book server communications
Lion Server Profile Manager specifies port 8843 as port for SSL communication. I only saw 8443 listed in documentation
The response "can't connect .." or "account verification failed" happens very quick which make me think either the verification doesn't even leave the iPad or there is something wrong in the SSL connection
Since iCal set-up works nicely using the same ports I am puzzled why it doesn't work for Address Book
Your solutions or suggestions how to investigate are most welcome,
Erik

Thanks for joining the discussion.
Although port 8443 is mosten quoted as correct port for CalDAV and CardDAV, port 8843 can be found both on Apple's website and other places:
see Technical Note 1649 to find port 8443 listed for iCal and port 8843 for Address Book
Mac OS X Lion Server for Dummies (sic) lists port 8843 on pages 236 and 238 but port 8443 in many other places
when you want to push iCal and Address Book information with Profile Manager, Profile Manager lists port 8443 for iCal but port 8843 for Address Book as default:
So I hope you understand I'm somewhat puzzled.
I did get the Address Book working for my Lion desktops with the all the necessary certificates as far as I know, just not for the iOS devices (iPhone and IpPad). iCal sharing from Lion Server works fine on both Lion and iOS devices.

Lync Client Can't Download Address List and other problems

We're currently in the process of testing for a production Lync Server 2010 deployment and we're run into some problems. I've been digging around on the Internet and the Technet forums but can't find a solution to this problem.
Whenever someone logs in with the Lync Client, they are immediately presented with prompts for user credentials. No credentials work. When you cancel out, you can still chat, but there is an error that says the Address Book can't be downloaded. I've confirmed
that the SSL certificate works, I've made sure the Kerberos Account is configured properly, I've reinstalled the Web Components, and I've tried numerous other solutions I've found for this issue. Nothing seems to fix the problem. When I try to run test-csaddressbookservice
in the Management Shell, I get the following:

My situation was somewhat different but running Test-CsAddressBookService would fail with error:
'The remote server returned an error: (404) Not Found.'
All clients were unable to retrieve contact unless the full sip address was entered.
Environment.
Server: Lync2013 STD
Client: Lync2010
Did the following:
Checked replication under the Topology tab in CSCP- mine had a green check.
Reinstalled .net 4.5 via add/remove programs
Registed .net by running the following from an elevated cmd (run from .net folder) : aspnet_regiss.exe -I
uninstalled Lync webcomponents from add/remove programs
From Lync install media- reinstalled webcomponents.msi (browse to \Setup\amd64\Setup)
Checked IIS>Application Pool and ensured all ASP.NET and Lync components are set to v4.0 of the .Net Framework Version
Launched the Lync setup and reran step 2: Stetup or Remove Lync Server Components.
Reran Test-CsAddressBookService:

10.7 Client can't join 10.8 OD

Hi everyone,
did anyone of you encounter this problem? I have set up a new 10.8 Server, DNS, OD, AFP, etc. all working fine. I can join 10.8 Clients without a problem, login and network home also works fine. But I can’t join an older Mac mini running 10.7.4. This machine is not 10.8-compatible, but I thought that it’s at least capable of joining the OD of the 10.8 Server. It was bound to a 10.7 OD before without a problem. But when I select its (autodiscovered & correct) DNS name from the Users/Login options prefpane all I get is the initial message that the server uses a self-signed SSL certificate (true & also shown on 10.8 clients). After selecting Trust I only get "Could not connect to directory server". Error -2100
Any ideas what’s causing this?
Thanks
Björn

Don’t ask me why, it is working now.

Microsoft lync client can make calls but not receive them

So I have our Lync server all set up…I can make outgoing calls, but I cannot receive them on my client. I have the URI fully populated with my direct line. Why can’t I receive calls? I have this integrated with my call manager as well.

Hi,
1. Please try to check mediation server listening ports.
2. Please also make sure do populate the telephone number field in AD user’s account. Please refer to the following link to verify if LineURI is set correctly.

Lync client can't fetch the address book files

Hi,
We have 3 FE Lync 2010 servers. All the clients are giving an error "cannot synchronize with the corporate address book".
I can access Internal Web services URL and download the AB file. I have also made an entry for Lync Internal web services in the host file and signed into the Lync. Then the client was able
to download the Address book files successfully. Any ideas to resolve this.?
Thank you !

Force a contact list update to make sure that your information is synchronized. To this, follow these steps:
Locate one of the following folders, depending on your operating system:
For Lync 2013:
Windows 7 and Windows 8: %localappdata%\Microsoft\Office\15.0\Lync\sip_<sign-in name>
For Lync 2010:
Windows 8, Windows 7, or Windows Vista: %localappdata%\Microsoft\Communicator\sip_<sign-in name>
Windows XP: %userprofile%\Local Settings\Application Data \Microsoft\Communicator\sip_<sign-in name>
Delete the following files:
Galcontacts.db
galcontacts.db.idx
CoreContact.cache
ABS_<sign-in name>.cache
Mfugroup.cache
PersonalLISDB.cache
PresencePhoto.cache
Restart Lync, and then wait for 30 minutes for resynchronization to finish

Lync Client Behind A Proxy

Can anyone confirm if the Lync client can be configured to route traffic via a proxy, or to use the proxy settings defined in IE?
I have the following scenario...
The environment is heavily locked down, and PC's only have access to the Internet via a defined IE proxy. Internal IM, presence and communication all work fine. We have configured federation with some remote organizations. IM and presence
works fine to these orgs, but when any A/V or application sharing is attempted, the media fails. I can see from traces this is when the client tries (and fails) to access the A/V edge of the remote federated parties edge server.
I've looked at the Lync settings, reg settings, group policy ADM and documentation, and cant find anything to a) confirm if this behavior is correct or b) any way to work around it.
There must be other Lync implementations in hardened environments like this. Opening up outbound ports is out of the question, so what other options do i have?
Dave

Jay, you missed the key word in my last post "internally". Functionally, everything about the edge server is working fine. Clients can login internally and externally. Media flows from internal to external clients is fine. All SIP/AV/WEBCON
DNS entries are fine in public DNS along with supporting SRV records. These interfaces are Nat'd and the AV address is correctly assigned.
My problem only occurs when an AV session is attempted with a federated partner...
When any AV or sharing is attempted, from the internal network, to the federated partner, i can see the Lync client attempting to make connections out to the remote federated partners AV edge (something which it will never be able to do as it's behind a
proxy with no direct Internet access). This is what I'm trying to address.
Should the SIP/AV/WEBCON address exist INTERNALLY
on the corporate DNS servers for internal clients to resolve? Is this what i have missed?
Is there anyway to instruct the Lync client to route traffic bound for the Internet via a proxy?
Surely there must be someone else with this scenario in a locked down environment?

Can lync client use internet proxy settings to proxy edge servers, if direct access is not reachable?

Hi everybody I am trying to Login with my lync Client out of my organization. So I am using lync as a remote user. I am in another organization, and I am using their coporate lan wired and wireless, but I cannot Login to lync in my organization.
I see that I cannot Access my edge Server on port 443 to authenticate directly, I know that Client in this organization use Internet Proxy to browse the Internet. they have a .pac in their ie Settings.
my question is; can lync Client use Internet Proxy Settings to reach the Destination? I mean the Access edge on port 443?
or it can use only Client direct Access to reach the edge Servers?
I Think that the answer is that I use tcp protocol and not http, and maybe that is the reason why I cannot use the Internet Explorer Proxy Settings to reach the Access edge Servers, different maybe is the case I Need to reach the reverse Proxy for live Meetings.
Hope my question is clear.
Thanks

Proxy settings are used to tell Internet Explorer the network address of an intermediary server (known as a proxy server) that is used between the browser and the Internet on some networks.
Lync client doesn’t use Internet Proxy Setting. You need to access the Edge service directly.

Lync on Mac 10.8 fails to join meetings

Hello all,
I'm facing an issue since upgrading from OS X 10.6 to 10.8 that the Lync client 14.0.2 frequently fails to join meetings. If I retry enough times, usually I'm able to finally join. I rely on Lync meetings multiple times every day so this is a big issue for
me. Here's the error message I get:
"Unable to connect. Try connecting to the online meeting by using the web browser that is currently open."
Any ideas?
Thank you,
Evan

Thanks Rusty. It bothers me that this problem has existed for so long now.
If you all are not aware there is a fully functioning "workaround." Using lync, call into the meeting as if you were calling from into a regular concall, then put in the meeting pin. As soon as it realizes you are on lync the
meeting will be setup and it works fully, but it is really annoying to have to do each time.
I did install 14.0.4 as well today, no immediate change in behavior for me. Tried changing to external only manual sip/tls and it seems to be working in terms of creating meetings, but only if no others have joined at the time I create it. Joining
existing meetings does not work, like before you connect to the meeting, but the phone shows as a * (unconnected or issue I believe) and sharing sessions will not reliably start. After a minute, lync will show a random person from the meeting as calling
you. Answering does not join you to the conference.
So Microsoft still has some work to do to resolve this issue.
As for the rest with the keychain issues. Yep, the assigned one is expired from the outset. I went to a 10.7 system and checked, it was also set as expired there, so I'm not sure it matters but who knows. I've also tried allowing all certs
etc many times, but behavior was unreliable at best. The workaround above is the only thing that always works.

No meetings option in Lync client

Hi I recently installed Lync 2013 server. In LAN I have lync.doamin.local certificate and outside I have public one. Users started using Lync. We wanted to test it and 3 people wanted to join.
I noticed several issues.
1. From within the lan - from the pc that is domain joined where office 2010 and lync 2013 are installed when user follows the link for the meeting, Chrome opens and it wants to install web client - which at the end is forbidden by admin. So although there
is a lync client present and user is signed in - meeting lync wouldn't open with lync client.
I tried the same with internet explorer but I white page opens with only Lync written and language choice.
In registry there is entry for Explorer to start automatically for a=Lync.exe ....
How to open lync client automatically?
2. Lync client installed on domain joined machine I don't have meeting button - just contacts, conversations and phone.
How to enable this button??
3. From within the lan - from the pc that is not domain joined I am getting certificate error that cannot be checked and that is not to be trusted.
How to overcome certificate issue?
Can you please advice? Thanks

Hi MrAlexandar,
As for your questions:
1. Is the meeting URL like this
https://meet.domain.com/xxx/xxxxxxx?sl=1 ?
If this is the case, please remove “ ?sl=1 “ and retry.
2. Install the latest update for Lync 2013.
And also install the update KB2837643 which includes the image dll files needed.
A similar case:
https://social.technet.microsoft.com/Forums/lync/en-US/d9bdca05-ec90-4eb8-af2b-c3c9e2352eb6/lync-client-2013-meeting-icon-disappear?forum=lyncprofile
3. Do you mean that the user cannot sign in Lync ?
If this is the case, please install the root certificate on the computer.
Best regards,
Eric

Hi
Is that Port 443 opened? check the fire wall.
is that external Lync clients are logging in with out any issues.
by seeing the Log it is unable to connect on port 443

Join Online Meeting link launches the Web App even though the Lync Client is installed.

Hello,
I have this problem on a few computers. When I click on the "Join online meeting" button or link (https://meet.###.com/###/1wnj6l1n) the web page launches the
webapp instead of a session in the full Lync client that I have installed (v. 4.0.7577.0). There is not a ?SL= at the end of the weblink.
I searched online to see if there was a registry setting that auto-bypasses the client check, but there isn't. I have tried a repair on the Lync client, but still no luck.
Has anyone else run into this problem?
Thanks.

I found the answer. The Https:\\meet.domain.com was opening in the internet zone with Protected mode on. I added the URL to my trusted sites and it was no longer an issue. I didn't test it but turning off protected mode may work as well.

Hi,
Did the issue happen only for you or for multiple users?
You can try to logon other Lync client on other computer with your Lync account as a test.
It may cause by the conflicts between the Lync client and some drivers or some third party programs installed on the computer.
Please check if you install Bluetooth utility on your computer? If yes, please remove it and test the issue again.
Please also run Clean Boot to disable thirty party services and then test again:
