Lync 2011 for Mac - "sign in failed, service not available"

I can't sign on to Lync 2011 for Mac at all. I'm running OS X 10.7.2, Lync 14.0.1 (so yes, I've installed the patch) and regardless of what else I do I get the message:
"Sign in to Microsoft Lync failed because the service is not available or you may not be connected to the internet."
Obviously I'm connected to the internet, I've checked the firewall settings and the 3 other troubleshooting articles on the Mac Lync site. I've deleted the "unknown" certificate from Keychain that some people talked about being the source of their
issues, but no luck. What's going on here?

Hi amoss,
Any update?
It may due to Root CA is not trusted.
You should trust the correct Root CA in the Keychain Access on your Mac machine.
In addition, provide this
troubleshooting guide for reference. Hope helps.

Lync 2011 for MAC not connecting externally to On-Premise Lync 2013

Hello,
Hopefully someone has some idea on this or a better direction for me to follow. So currently I have an issue where Lync 2011 for MAC clients will not connect when external to my On-Premise Lync 2013 servers. Everything to do with my Windows based clients
and even cell phone based client’s works just fine. It is currently only Lync 2011 for MAC which will not correct externally.
I did initially have the logon problem internally as noted by other posts online when using an internal CA certificate with Lync. But with the internal certificate imported onto the MAC when internally connected Lync 2011 will login just fine. Now in my
setup I do have a TMG server that clients are connecting to that forwards the connections onto my Lync servers when connecting externally. When I review live real time logs to see what’s connecting to the external URL for Windows based clients I can see them
connect in on port 443 no problem.
But with the MAC I don’t see any attempt from it to connect to the URL like I see with the Windows clients. Now below is what shows up in the Microsoft-Lync.log generated by the MAC. Now initially looking at the log I thought my problem was the fact when
Lync 2011 tires to connect when external that it was doing so on port 5061 which we don’t have open. So I tired entering external.mydomain.com:443 in for my external server in the setup.
And while rechecking the log after doing so shows like it is now trying to connect on port 443. When reviewing TMG I again see no connection attempt by the MAC to connect to the Lync external url or on port 443. Further research so far into the problem has
come up empty on the subject. And most other cases where people report problems connecting externally they are using some form of online service like Office 365. So at this point I am not even sure if Lync 2011 for MAC is supposed to work externally with On-Premise
Lync 2013 deployments or not. If anyone has an thought’s or idea’s please share them as at this point I am stuck on this issue.

Hi Nicholas Sayewich,
I tested in my lab and without any problem.
I also use TMG as Reverse Proxy and without configuring SRV records (My ISP don’t support SRV), after importing the root certificate onto MacBook, I can sign into Lync everywhere(internal
and external).
Please make sure that the certificate is set up to
Always Trust .

Lync 2011 for MAC and Lync 2013 Server Std

Hello,
We are using a Lync 2013 Std (single-server) as a POC. It works fine for Windows-clients but I cannot connect using Lync 2011 for MAC from any MAC machine.
Using automatic configuration, I cannot connect to the Lync server.
Using manual configuration (I tried putting in just the server name and adding port 5061 to it, both to no avail) I keep getting 'Sign in to Lync failed. Please verify your credentials and try again.'.
Lync server is on the latest CU version with all components, MAC clients are on update 140321.
I noticed that Lync tries to create the OC_keycontainer_username@domain, but it seems not te be created. It flashes by and disappears again when the client fails to login. I have imported the Lync server certificate, issued by our windows 2012
root CA, on the Mac clients and have stored it in the 'Login' container.
Does anybody know if Lync2011 for Mac is supported for use with Lync server 2013 Std?
Cheers

Hi,
To clear cached data and corrupted certificates in Lync, you can do the following steps:
First, delete the following folders:
Users/Home Folder/Library/Caches/com.microsoft.Lync
Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync History
Then, delete any corrupted or cached certificates. To do this, follow these steps:
1. Open the Keychain Access certificate management utility. To do this, in Finder, click Applications, click Utilities, and then click Keychain Access. Or, search for Keychain Access by using Spotlight.
2. In the left pane, click login, and then click Certificates.
3. In the right pane, find a certificate that's named Unknown or Communications Server, select it, and then delete it.
Note: You may have to unlock your keychain by using your password.
4. Close Keychain Access.
5. Restart Lync for Mac.
You can refer to Lync Mac for Lync Server online, but similar for Lync on-premises:

Contact pictures not displaying in Lync 2011 for Mac

Using Lync 2011 for Mac I'm not seeing any contact pictures (including my own), though I can see them when signed into Lync 2013 on a Windows PC (7, 8.1, and 10 Technical Preview for Enterprises).
My company uses O365 hosted Exchange and on premise Lync Server.
I'm using OSX 10.10.1 (on a 2014 Air) and Lync for Mac 2011 14.0.10 (141024). I have AutoUpdate set to automatically check weekly and I manually checked (button at the bottom of Microsoft AutoUpdate) so I believe I'm running the current release.
Logging in with another user account on my same Mac/Lync install has the same issue
Another user account on their own Mac also has the same issue
It's also worth noting that the same issue arises when signing into Lync for Android and iOS as well, but not on Windows (Lync 2013).
Any thoughts? Thank you very much for your time and assistance.
Also, my apologies for putting this question in this subforum, but I didn't see any main forum for Office for Mac or Lync 2011 or Lync for Mac at all. If there is such here on technet, please drop the link here and I'll move the thread.

Hi abacus02,
On mobile, you have no control over how photos are displayed. Lync Mobile can only display photos retrieved from Active Directory or SharePoint, it cannot display a photo from a URL. If a user
is displaying a photo from a URL and there is a photo in AD, it will display the photo from AD. If there is no photo in AD, it will display no photo at all.
About Lync for Mac, as I know Lync 2011 for Mac does not support high resolution images. Only in Lync 2013,
In Lync 2013, when the user’s photo experience has been migrated to Exchange 2013 and they are using Lync 2013, high resolution photos can be used.
So please tell us where the photos are stored, we need more information to troubleshoot the issue.
Best regards,
Eric

Lync 2011 for Mac

Client has Lync 2011 for Mac on a MacBook running mavericks and it crashes right after I log in and am getting the EXC_BAD_ACCESS error.
I have tried all of the suggestions I could find on the internet already and nothing has worked. I have even tried the RTM, SP2, and 14.07 version. I would try other versions but can't find them anywhere to download
Here's the kicker - they have Lync 2010 (all latest updates installed). If I log into our environment which is Lync 2013 using a test account it works just fine. Also if I log in using a test account from a different environment that also has Lync 2010 it
also works just fine. So it seems it is some kind of interaction between the client and their server environment that is causing the crash and not something locally on the client machine. None of the logging I have done shows anything of value.
Does anyone have any ideas why it would work using other environments but not this one?

Did you mean that you can use the same Lync 2011 for Mac on the same computer to sign in successfully to connect other Lync Server?
That is exactly what I mean. On the same computer using the same client I can successfully connect to two other Lync server systems and it doesn't crash at all. So what on the Lync server of this one system would cause it to crash?
Please try to create a new user account, then login with the new user account, sign in with Lync 2011 for Mac again.
I tried that as well and I got the same problem with the client crashing right after I sign in.

Can you add the contact by searching the SIP address?
Please check if the files GalContacts.db and GalContacts.db.idx are updated in Lync users’ profile folder.
I guess these files are not updated.
If this issue happens with several Lync users, you can copy these two files form users’ profile folder to replace the ones in problem Lync users’ profile folder to confirm that.
Try to run the command Set-CsClientPolicy –Identity -AddressBookAvailability WebSearchOnly, then sign out Lync for Mac and sign in, check if you can search the contacts.

Hi,
As the issue happen only for Lync Mac client, so it should be the of Lync Mac client.
You can try to perform a Clean Uninstall for Mac Lync client and then test again.

Lync 2011 for Mac not saving conversation history on outlook 2011

I have MS Office 2011 on my MAC. I have noticed the conversation history is saved on the MS Lync History folder on the MAC. However the outlook mailbox folder called " conversation history " is not updated with this info. Any idea what could
be happening ?
OS : 10.9.5
Lync : 14.0.9
Outlook : 14.4.4
MS Exchange server 2013.

Hi,
For Office 2011 on MAC, the Conversation History isn’t stored in Outlook.
The conversation history is stored in the path: /Users/<username>/Documents/Microsoft User Data/Microsoft Lync History

First, delete the following folders:
Users/Home Folder/Library/Caches/com.microsoft.Lync
Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync History
Then, delete any corrupted or cached certificates. To do this, follow these steps:
Open the Keychain Access certificate management utility. To do this, in Finder, click
Applications, click Utilities, and then click
Keychain Access. Or, search for Keychain Access by using Spotlight.
In the left pane, click login, and then click Certificates.
In the right pane, find a certificate that's named Unknown or
Communications Server, select it, and then delete it.
Note You may have to unlock your keychain by using your password.
Close Keychain Access.
Restart Lync for Mac.
Important Before you perform the next step, try reproduce the issue by using a new test user account. If the issue doesn't repeat in the new account, then follow these steps:
Open Keychain Access Preferences, and then click Reset My Default Keychain.
Open Finder, locate the following folders, and then delete them:
/Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync Data
/Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync History

Mac OS X Midi services not available?!

Er...
About 5 mins ago Logic 8 was running perfectly. Then (as the studio I work for wants me running 7) I opened it once again for the first time in a few months (after deleting the application and reinstalling it) it started to validate my plugins, but gave me an error on Atmosphere (which I removed post Omnisphere upgrade) and I got an error saying that Logic had encountered an possible conflict with Midi audio drivers.
I just reopened Logic 8 and I've been told that Mac OS X Midi Services are unavailable - and when I opened AMS it's told me that it is Unable to Launch MIDI server!
I cannot think what it bleeps name has just happened?!

What "it"? Logic 7?

Still 7, all this, right?
I just reopened Logic 8 and I've been told that Mac OS X Midi Services are unavailable - and when I opened AMS it's told me that it is Unable to Launch MIDI server!
So Logic 7 'took' it? Did you quit L7?
Have you rebooted the Mac?
I cannot think what it bleeps name has just happened?!
If you had 7 open while launching 8, I'ld say 7 still had some sort of software-'hold' on the systems' coreMIDI or Midi services app. If you force-quit L7 the same could apply. If so, restarting your Mac should fix it.
The problem probably has to do with the double install. There was a reason for deleting and reinstalling in the first place, right?

Lync 2011 for Mac with iMessage on OSX inbound and outbound calls fail

Running Office 14.4.9 updates and many before that. If you activate or deactivate an iMessage account using the built-in Messages application, Lync can no longer make or receive calls. Calls received will automatically go to voicemail.
Outbound calls just ring and ring. The phone setting in Lync were all three set to Lync as well.
The only way I've found them to work is to following the first instructions at the following link:
https://support.microsoft.com/en-us/kb/kbview/2691870?wa=wsignin1.0
Log on to your computer by using administrative credentials.
Exit Lync if it's running.
Drag the Lync application to the Trash.
To remove your existing Lync preferences, delete the following files:
Users/username/Library/Preferences/com.microsoft.Lync.plist
Users/username/Library/Preferences/ByHost/MicrosoftLyncRegistrationDB.xxxx.plist
Users/username/Library/Logs/Microsoft-Lync-x.log
If you activate or deactivate an iMessage account steps 1-4 must be performed, otherwise, phone calls fail. One additional annoyance I've noticed is that Lync tends to hand with a red X on the icon in the dock when this happens as well. You must
use the terminal and do 'pkill Lync' in order to close it.

Hi MSGuest,
Can you install the latest update and then check again ?

Slow attachment upload with Exchange Web Services (Outlook 2011 for Mac?)

We're experiencing slow attachment upload with Exchange Web Services versus MAPI, OWA, and Outlook Anywhere. I'm not totally certain that it is Exchange Web Services or specifically Outlook 2011 for Mac. I attempted to test with the Mac Mail
App, but it makes it difficult to tell when the attachment has been uploaded and the file has been sent. Here's what we're seeing (10mb file):
MAPI / RPC/HTTPS / OWA: 10-15 seconds upload time
Exchange Web Services (Outlook 2011 for Mac): 60-90 seconds upload time
Thoughts? Any idea why we would see such a drastic difference in attachment upload time? Any way to prove definitively that it is Exchange Web Services vs. Outlook 2011 for Mac? We've tried it from multiple locations with multiple different machines,
and although the upload times vary (some locations have more bandwidth etc) the ratios remain similar.

Hi ,
Does all the user occurred the issue ?
If only special user, I recommend you do the following steps and test:
1.Remove and re-add the email account and check if this helps to resolve the issue.
To remove and add the email accounts:
Open Outlook > GO to Tools > Accounts > Click on "Minus" symbol to remove and "Plus" to add an Email account.
2.Creating a new user profile:
http://support.microsoft.com/kb/2439218/
3. If the issue persists, rebuild the data base and check the results:

Can't activate Office 2011 for mac (downloaded from office 365 portal)

Hello All,
I've installed Office 2011 for mac which was downloaded from office 365 Portal. However, during installation process there was not a windows for activation (key or sign in method).
Is there a way to force activation on Office 2011 for mac?
Note: I've deleted office 365 com.microsoft.office.plist but i didn't get a windows for activation.
MacbookPro Version 10.10.2
Regards
JO

Hi,
If you downloaded Office 2011 for Mac, you may not need a product key to activate it. Office 365 uses a new mechanism that the activation is based on your Office 365 Account instead of a product key.
Anyway, in this forum we mainly discuss questions and feedbacks about Office for Windows, as your question is about Office for Mac, I suggest you post the question in Office for Mac forum:
http://answers.microsoft.com/en-us/mac
I've also noticed this question is actually more related to the activation, you may need to contact the local customer service to get more dedicated assistance:

I cannot send email from Outlook 2011 (for Mac). But can send from other applications

I have Outlook 2011 for Mac - I have validated the settings and up until yesterday could send and receive emails using my .mac account.
I can send using icloud and mail (I use Outlook for work purposes) and can send in outlook using my work accounts.
My settings
Incoming server - imap.mail.me.com
Use SSL to connect checked.
Outgoing server - smtp.mail.me.com
override default port checked (port 587)
use SSL to connect checked
authentication - Username and password.
I have rebuilt the database - no effect.
I continue to get the error
"Mail could not be sent
The server for account "mac" returned the error. 5.7.8. Bad Username or password (Authentication failed..)" Your username/password or security settings may be incorrect. Would you like to try rentering your password"
I have validated my username and password and rentered them both.
I have emptied the outbox and retried but nothing works.
Thanks for the help.

Update - I now have it working.
am not really sure what exactly fixed it.
I changed a lot of things but my setup now has the following which I think fixed.
outgoing server - p06-smtp.mail.me.com
override default port checked - port now 587
on more options button changed it to "use incoming server info".

So when I installed the most recent updates for microsoft office 2011 for mac, my ical info disappeared. Still have the info on my Office calendar but it's no longer on ical. It's also been removed from my phone. How can I get outlook to sync with ical

When I installed the recent updates for Microsoft Office 2011 for Mac, my iCal calendar was wiped out, as was the calendar on my iPhone. I'd rather use iCal than Office and was attempting to phase Office out altogether. Now, all of my information is on the Office calendar but not iCal. The iCloud version of my iCal calendar is not up to date. In any event, I couldn't figure out how to send that info to the iCal on my mac or my phone. How can I sync my Office calendar info to iCal? If that's not possible, how can I get my Office calendar to sync with my iPhone? All of my sync services are set up in iTunes and on my phone. This happened to me once before and I spent hours on the phone with Apple and on the web trying to work it out. I NEED MY CALENDAR!!!! PLEASE HELP!!!!!

As that's not an Apple product, you may get more help by using Microsoft's Office for Mac forums:
Office for Mac forums
The other concern I have is that Office 2011 requires an Intel-based Mac and you posted in the older iMac (pre-Intel or "PPC") forums. If you have an Intel-based iMac (Apple menu > About this Mac..." will say "Intel" if you do) then I think you'll get faster and more accurate ansers to other questiosn in the Apple forums for newer iMacs here:
