Reply Yongrak Cho says: December 15, 2011 at 6:24 pm Thanks for your recommended !! Can someone help? Everything works fine internally and my EWS shows an INTERNAL URL. The certificate request on a Director fails to automatically include the autodiscover FQDNs so they must be manually added in to the request which is covered in a later step in http://bestimageweb.com/connect-to/lync-cannot-connect-to-the-exchange-web-server.php

I'm not sure if this is a WordPress issue or Windows Live Writer is to blame.

Something doens't sound right with that server in general as it should be there.

I can also press the keypad icon in the top left corner to get a dial pad where I can make calls. Exchange Connectivity Test Just sure when you integrate IM into OWA did you patch also the Lync UCMA on Exchange CAS? Basically, our ews directory is still under the mail.domain.com url, so even though we have published the autodiscover and ews folders with a separate listener and publishing rule, the ews folder I've been trying to avoid it, but it looks like I need to about 16 new SAN names to my certificate. 🙁 Reply @RobersonBrian says: December 17, 2011 at 10:24 am

I set this up in my personal lab to debug and run through this before I have to implement it for a major customer later this week. The HLB for OWA is internal and works just fine.

Reply jeffschertz says: December 16, 2011 at 6:47 am This sounds like a DNS configuration issue then if the URL works manually. http://bestimageweb.com/connect-to/iphone-lync-cannot-connect-to-exchange-web-server.php You can try again later. Looking forward to your response . Resolution: 1.Publish your internal EWS FQDN in public DNS and make sure your TMG or UAG server has a certificate matching the public name you're using.

For those who just need the download links, here they are: Lync Server Cumulative Update 4 Downloads - Microsoft Downloads Lync Server 2010 Mobility Service and Autodiscover Service Components - Microsoft These will not exist on Director Servers since the Mobility service is not installed on them. Reply Rune Flo says: December 15, 2011 at 4:52 pm Hi Jeff, The last step, signing-in to Mobile Lync with the SIP address and [domain account] password. http://bestimageweb.com/connect-to/lync-cannot-connect-to-exchange-web-server.php What am I missing here, do I need to reapply all the steps following the msi bootstrapper installation?

My question is whether the external DNS SRV record for _sipfederationtls._tcp.domain.com is also required to allow notifications with the PNCH to work. It's a free add-on which essentially expands your Lync setup to include mobile devices. That'll light up your EWS settings in LYNC.

I have had no success at all getting the mobile client connecting to EWS since initial implementation.

Reply jeffschertz says: January 18, 2012 at 7:44 am I have not run into this, I suggest checking the TechNet forums as I've seen this topic come a few times already. Therefore it is necessary with your internal DNS that you publish the autodiscover and_autodiscover (SRV) records internally and let them point to the O365 address. I have a Host A record defined with name and an SRV record.The Lync Client resolves this.Name: autodiscover.testlab.localAddress: 192.168.10.25an SRV record _autodiscover._tcp.testlab.local SRV service location: priority = 0 weight = 0 C:\ProgramData\Microsoft\Lync Server\Deployment\cache\4.0.7577.0\setup\ Using the Lync Server Management Shell change to the Deployment directory and run the Bootstrapper application using the following commands.

Thus in an internal-only test environment the clients will always connect to the internal Mcx web site, but in a full deployment with external access then all clients will be passed No Comments Enterprise Voice, Instant Messaging (IM), iPad, mobile, Presence, Voice over IP Leave a Reply Name (required) Mail (will not be published) (required) Website Allowed tags: see here This approach simplifies user authentication and takes the internal namespace out the loop for end-users, but is the same best practice I typically use in deployments.

Double check those Keys too: HKCU\Software\Policies\Microsoft\Office\x.0\Outlook\Autodiscover On the Exchange CAS Servers, you also should check manually on the EWS and the Default Website, if NTLM is the first choice for authentication It might be unavailable. We have installed everything as above and for external clients everything works as intended but external clients will not logon. Click here to view the article titled "RESOLVED: Lync iOS Mobile ERROR: Can't connect to Exchange Web Services.

Apparently the new clients do not support authentication on TMG, so i had to change the delegation to "No Delegation, but client may authenticate directly" and users to "all users". Download the McxStandalone.msi installation package and save it into the following existing directory on each Lync server where it will be installed. Or, even worse, use one listener...but skip authentication on TMG and forward all to CAS directly? Is it possible to have mobility work without the autodiscover portions.

Install IIS Prerequisites The Mobility Service uses the Dynamic Content Compression component of IIS Which was not a prerequisite Previously component for Lync Server, It Must Be installed so only on Apply the changes to TMG to complete the configuration.
