Outlook 2011/365 connectivity to Exchange 2010

Hey Everybody,
I'm running into a little bit of jam with Outlook 2011/365 from my Mac population to Exchange 2010 SP3 Rollup 8 v2. I have read many articles and discussion forums regarding the issues with SSL and TLS connectivity. I have verified that my windows host with
Outlook are just fine in setup and use of the Exchange server. 
The Mac systems are having the issues. Autodiscover is working ok and IPhone/Ipad configure just fine. We really only have two, so this is why it was a surprise.
If I browse to the EWS directory it is just a blank page receive from any browser on the Mac's. 
What is the issue with Outlook 2011 and 365 connecting to a exchange system during configuration?
Would joining the Mac's to the domain make a difference?
With Poodle being one of the most recent risks, what should Mac user be configured as to not bring a security risk to the rest of the environment. 
Is reseting the virtual directories a possible action or is the most common issue just SSL and TLS compatibility?
Is there anyways around this without having to turn on basic security  on EWS and fall back to SSL instead of TLS? 
What is the best ways of testing connectivity with logging other then just seeing the error 17997 from Outlook on the Mac.
Thoughts? Recommendations? Tips?
Thanks, 
Matthew

Hi Matthew,
According to your description, I noticed that the issue doesn’t happen in Outlook for Windows but occurs in Outlook 2011 for Mac.
Please access the EWS URL from Internet Explore in Windows instead of Mac machine, and check whether a proper XML file is returned. If the XML file returns in Windows for the problematic account, it indicates the EWS service should be working in Server side.
The issue may be related to client side in Outlook 2011 for Mac machine, I suggest we can ask a question in Outlook for Mac forum for more help:
http://answers.microsoft.com/en-us/mac/forum/macoutlook?tab=Threads
If the EWS service doesn’t work in Windows either, please check whether users can view free/busy information in OWA. Then run the following command to check the EWS configuration in server:
Get-WebServicesVirtualDirectory | FL Identity,*AUTH*,*url*

  • Exchange 2013 / 2010 co-existence - Outlook won't connect to Exchange 2010 mailboxes

    Greetings!  I have a lab set up at home where I have been testing co-existence of Exchange 2013 and 2010 for a future corporate upgrade project.
    I am running into some odd behavior.  Any mailbox that has been migrated to Exchange 2013 works just fine, however, when I try to set up Outlook for a mailbox still on Exchange 2010 I  receive errors.  OWA works just fine for these Exchange
    2010 mailboxes, it is just Outlook that has the problem.  This is what I am running into:
    1. Outlook uses autodiscover to locate server settings.  It fails at the 'logging on to mail server' step saying that Exchange isn't available; Outlook must be connected, etc.
    2. It then gives me the settings box for Exchange server and Mailbox.  This is auto populated with one of the Exchange 2013 servers (there are 3 of them, all have both MBX and CAS role).  If I then change the server to the Exchange 2010 CAS server,
    and hit 'check names', it underlines the very same entries (like it found them this time) that were there initially and goes on to finish the configuration.
    3. When I launch Outlook with this Exchange 2010 user, it fails to open with the error message that the set of folders couldn't be opened.
    I've been doing as much research on this as I can.  I've tried disabling IPv6 to no avail.  It seems as if perhaps the issue is with Exchange 2013 proxying the request back to the Exchange 2010 servers but I am not sure what to check in that regards. 
    Any suggestions?  Thanks in advance!

    Hi,
    Don´t disable IPV6 on an Exchange Server, it is, in my opinion not necessary - also applies for AD.
    You can use your original SSL Cert for your new Ex 2013 environment.
    In dns you want two host A records: mail.domain.com and autodiscover.domain.com
    On your 2013 set your internal and external virtual directories to mail.domain.com
    leave autodiscover and Powershell alone.
    Also set the autodiscover URI to your Certificate name ie. mail.domain.com
    Set-ClientAccessServer -Identity "YourCASServer" -AutoDiscoverServiceInternalUri "https://mail.domain.com/autodiscover/autodiscover.xml"
    Thanks.  I wanted to give some additional info before I run any commands.  I currently have an A record for autodiscover and it is pointed to the Exchange 2013 DAG/cluster IP.  I have a 3 entries for mail.domain, for DNS round robin; basically
    it is listed 3 times for the IP of each of my Exchange 2013 servers.  Does any of this sound problematic?

    Hi,
    The connection in Outlook 2011 for Mac is difference from the Exchange connection in Outlook for Windows. The Outlook for Mac is using EWS for Exchange connection.
    According to your original posting, there seems to be some issue with your autodiscover service. And some Exchange services (such as OAB, OOF, OWA etc.) are using webmail-01.xx.com namespace in the URL. Please double confirm the configuration in your Exchange
    server.
    Additionally, please check the autodiscover service on Outlook for Windows machine. If all configurations in server side are correct but the issue persists, I suggest we can ask a question in Outlook 2011 for Mac forum for more help:

  • Outlook 2013 cannot connect to Exchange 2010 SP2 server, Outlook 2010, OWA work fine. Ideas?

    After upgrading a laptop from Outlook 2010 to 2013 it can no longer connect to our Exchange 2010 SP2 environment.  OWA works, Outlook 2010 works, but Outlook 2013 will not create a profile via AutoDiscover.  The first two checks go, the last check
    Log On To server will not.
    We can take the laptop to a different network and it works fine with Outlook 2013.
    What is different with Outlook 2013 where it will not connect.
    Jason Meyer

    Does it work when we recreate a new Outlook profile?
    At this point, We high recommand that we run Microsoft Connectivity Analyzer Tool from the folloing link to check what was happening

  • Windows XP SP3 and Outlook 2010 can't connect with Exchange 2010 or Exchange 2013

    XP+SP3+Outlook 2010 can't connect to Exchange 2010&2013 in the internal network without safe mode.

    Hi,
    Did you get any error messages?
    Do you have Outlook Anywhere and autodiscovery set up properly?
    Can you ping the Exchange server?
    Please use Test Email AutoConfiguration
    to test if the Autodiscover service is configured properly. See:
    https://hosting.intermedia.net/support/kb/default.asp?id=2150
    We can also use the remote connectivity analyzer to troubleshoot the issue:

    In addition, turn off your firewall and anti-virus to check the result.
    Hope this helps.

  • Cant Get Mac Mail ( or Outlook 2011) to connect to Excange erver

    When connecting via IPAD it took 30 seconds to set up.
    I cant get it running from MAC Mail nor Outlook 2011 for MAC.
    Exchange "Server not responding".
    It runs great from Outlook Web Access on the mail or from VmWare running Win 7 with Outllok 2007
    H E L P !!

    +1. Me, too. Any solutions? Every few months I spend a lot of time looking for workarounds for this issue. I tried with Mail, and recently I tried the new Microsoft Office. No luck. I work from home and the company I work for uses an exchange server. I'm stuck with Entourage 2008. It's a real bummer.

  • Outlook 2013 not connect with Exchange server 2013 in internal network

    Hello All,
    I Have two Exchange server 2013 in our environment. Both server install mailbox and CAS role. After configure exchange server 2013, Outlook 2013 not connect in internal network. I have configure outlook manually. i tried by using the suggestion from blog
    but not work. Outlook show that Server cannot connect/ server name could not be resolved. in outlook setting i also put exchange proxy setting. In exchange admin center i have changed the OWA, OAB, Auto discover name. But still not work.
    I know that outlook can be connect from external by using ssl certificate and publish outlook anywhere but i did my configure from internal network. 
    Can you please suggest as soon as possible.
    Thanks,
    Parvez

    Hi,
    Firstly, I’d like to explain, same with external users, internal users use Outlook Anywhere to connect with Exchange server and use Autodiscover get all settings.
    Thus, let’s try the following resolutions:
    1. run the following command: get-clientaccessservice |fl autodiscoverserviceinternaluri
    2. check if the host name in the above URL is in the DNS server and there is a DNS entry about the host name points to the proper IP address.
    3. Check if the above host name is in your certificate.

  • Outlook Can't connect to Exchange Server

    Dear All;
    I install the exchange server 2013 in our Environment with basic configurations, it was work correctly in out look and OWA.
     In this period I install  outlook Clint  and connect to exchange correctly , Then I log in to Exchange Administrations Center , then make some changes , after that i can't connect  outlook Clint  to exchange server  while I
    can connect to OWA but with error message related to Certificate.(Kindly check the screen shoot of error )
    Kindly help me to solve this issue I beginner  with Exchange.

    Here are the default permissions for the Exchange virtual directories:
    http://technet.microsoft.com/en-us/library/gg247612(v=exchg.150).aspx
    I found that the print in the screenshots was not clear - maybe it's me or my browser.
    What names do you have on the certificate?
    exchange.abc.local
    Is that it?
    Is this a self-signed certificate? Or did you get it from Digicert, VeriSign, GoDaddy or some other 3rd party authority?
    Regardless, the URLs for the virtual directories, OWA in particular, have to match what is on the cert.
    So OWA might be:
    https://mail.exchange.abc.local/owa
    Other possibility:
    https://webmail.exchange.abc.local/owa
    Since exchange.abc.local is what you have on the cert, the URL has to configured as shown above. You can use "mail", "webmail" or whatever just before (once again, as shown above) but you have to make sure that is what the users enter
    when they attempt to access email.
    Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

  • How other email server (sendmail) will make connection to Exchange 2010 mutli role server.

    Hi,
    We have 2 Exchange 2010 multi role server and one load balancer for Cas array.
    Now we do understand that DAG will be using for database and CAS can be in HA mode via Load balancer.
    Now question is, we do have other non-microsoft email server with same smtp address so when this sendmail server will try to make connection to exchange 2010, which server name/ip we need to give them.
    Will it be DAG ip/name or do we need to give both server IP.
    Amit Rawat | MCITP - Exchange 2007/2010| CCNA |MCSE- 2003| Lync 2010|http://blog.amitrawat.net

    you can use whatever Ip's are listening on port 25 on the 2010 hub transports. 
    If your load balancer is listening on port 25 and balancing that (probably only a https loadbalancer?) you can use that ip.
    If not you can put your 2 cas server IP's in the smart host connector from the sendmail box.
    It certainly wont be the DAG ip as the mailbox role has nothing to do with the hub transport.
    Foremost i don't have separate CAS here, I do have 2 Exchange(cas/HT/MBX) and DAG is configured.
    when sendmail send email to Exchange i need to use some common smtp address to point these servers, so that if one goes down sendmail server can still make connection via that common name.
    i can not put two name space(since these 2 exchange are HT server as well) for sendmail server. Any suggestion .

  • Internal outlook client connectivity in exchange 2010 when coexist with exchange 2013

    Hi all ,
    on my side i would like to clarify few queries.
    Say for instance i am coexisting exchange 2010 with exchange 2013 .Unfortunately if all of my exchange 2013 servers goes down .
    Q1 .On that time will the internal outlook users having their mailboxes on exchange 2010 can be able to connect mailboxes without any issues ? In case if they face any issues what kind of issues will they be? Because why i am asking is we should have pointed
    the autodiscover service to exchange 2013 during coexistence.
    When an user closes and reopens the outlook after whole exchange 2013 environment failure ,outlook will first query the autodiscover service for the profile changes to get it updated on users outlook profile.In such case autodiscover service will not be
    reachable and i wanted to know will that affects the internal client connectivity for outlook users having their mailboxes on exchange 2010.
    Q2. Apart from outlook internal users connectivity ,what kind of exchange services(i.e owa,active sync,pop,external OA and imap) will get affected when whole exchange 2013 environment goes down during coexistence ?
    I have read the below mentioned statement on this awesome blog but still i wanted to clarify with you all on my scenario.
    http://blogs.technet.com/b/exchange/archive/2014/03/12/client-connectivity-in-an-exchange-2013-coexistence-environment.aspx<o:p></o:p>
    Internal Outlook Connectivity
    For internal Outlook clients using RPC/TCP connectivity whose mailboxes exist on Exchange 2010, they will still connect to the Exchange 2010 RPC Client Access array endpoint.
    For internal Outlook clients using RPC/TCP connectivity whose mailboxes exist on Exchange 2007, they will still connect directly to the Exchange 2007 Mailbox server instance hosting the mailbox.
    Please share me your suggestions and that would help me a lot .
    Regards
    S.Nithyanandham

    Hi Winnie Liang ,
    Thanks a lot for your reply.
    Scenario  1 : for internal outlook connectivity 
    We have below settings for exchange 2010 autodiscover.
    mail.domain.com - will be the namespace for internal autodiscover URI for all the exchange 2010 cas serves
    We are going to have below settings for exchange 2013 autodiscover.
    mail.domain.com - will be the namespace for internal autodiscover URI for all the exchange 2013 cas serves
    During coexistence mail.domain.com will be pointed to exchange 2013 cas servers . I mean to say if we try to resolve the mail.domain.com it will get resolved in to the exchange 2013 cas servers.
    So on such case if anything happened wrong to the new environment or else if entire environment goes down .Do we face any issues while outlook users connect to existing mailboxes in exchange 2010 ?
    Because why i am asking is ,on the below mentioned article i have read all the autodiscover request will go via exchange 2013 cas servers during coexistence.That means all the existing mailboxes in exchange 2010 will also have to query exchange 2013 cas
    servers for autodiscover request.During the whole exchange 2013 environemnt failure whenever the user tries to close and open outlook .Outlook will first queries the autodiscover service for any changes happened on that particular mailbox and it will try to
    get it updated on user profile.
    http://blogs.technet.com/b/exchange/archive/2014/03/12/client-connectivity-in-an-exchange-2013-coexistence-environment.aspx
    Would it be possible to make the exchange 2010 mailbox users to query only the scp points which belongs to the exchange 2010 cas servers for autodiscover request ?
    Scenario 2: For exchange services
    mail.domain.com - will be the namespace for all the exchange 2010 services (i.e owa,activesync,external outlook anywhere,pop,imap)
    mail.domain.com - will be the namespace for all the exchange 2013 services (i.e owa,activesync,external outlook anywhere,pop,imap)
    What about the above services will it get affected during whole exchange 2013 environment failure ?
    Note : We are not facing this issue , i hope everything goes well in my environment while doing coexistence i am just asking this question on my own interest?
    Regards
    S.Nithyanandham
    Thanks S.Nithyanandham

  • No calendar connection for Exchange 2010 + Outlook 2013

    My environment is this:
    Running Outlook 2013 (as part of Office 2013 Suite) connecting to Exchange Server 2010
    Both cached and non-cached modes
    Connecting using RPC
    With both existing profile for last 1yr+ and with a new profile
    Outlook v 15.0.4649.1001
    The issue I'm having is a room/resource calendar that I was once able to see I can't anymore.
    Running Outlook 2010 as the same user from a different computer works fine.
    OWA works as well.
    Other calendars work
    Running Outlook 2013 vs 15.0.4420.1017 also works on a different computer!!!
    So this seems to be an issue with my particular version of Outlook, and I did read where a security update seems to have gotten in the way (regression test lately?) but a December patch of 2013 was supposed to fix that. I didn't specifically install the
    patch, rather I downloaded from my vendor the latest available version they had.
    So is there a patch that will work for me. The only one I've come across tells me it isn't for my machine.
    Thanks,
    Joe

    Hi,
    According to your description and test, I understand that the room/resource calendar is invisible in Outlook.
    How about changing another user to log on your Outlook?
    How about the same version of Outlook on another computer?
    Please try to run Outlook under safe mode to avoid some AVs and add-ins.
    Please try to re-create profile for testing.
    If all method above doesn’t work, please re-install Outlook.
    Best Regards,
    Allen Wang

  • Issues connecting Outlook 2011 for Mac to Exchange Server 2013

    Could someone help me with the bellow please:
    I have a Mac with outlook 2011 on it.
    We have recently set up Exchange Server 2013, and all of the Windows Workstation just required the trusted root certificate to be installed and they were working.
    However I have spent hours reading different forums trying to get this working on the Mac and no luck.
    The auto discover does not work when setting up the exchange email, therefore I have also tried setting up manually but it still will not connect to the server.

    Please check if the links below help:

  • Outlook 2010 won't connect to exchange 2010 - logon box appears

    Users can't connect to Exchange server from outlook 2010.  The domain\user and password boxes keep popping up and will not accept the details.  It ends with "the connection to exchange is unavailable.  Outlook needs to be online to perform
    this action"
    I've searched high and low for an answer and none work.  Anyone any ideas?
    Exchange is behind Threat Management Gateway 2010, with applicable rules setup.  Strangeley, Outlook Web Access works fine with no problems what so ever.
    Thanks in advance
    Andy

    Ok.  Done some reading and made some adjustments but still pretty much the same.  Microsofts Exchange analyser tool come up with the folowing errors and does indeed pinpoint it down to the autodiscover service.  The srv record for the autodiscover

  • Outlook client in different subnet unable to connect to Exchange 2010 CAS using Windows 2008 R2 NLB multicast mode

    Hi all,
    need urgent assistance on the following issue
    this is my Exchange 2010 setup
    2 x CAS/Hub servers with HP network teaming, and load balanced using Windows NLB multicast mode. There are 2 VIPs on the NLB, one for outlook anywhere, one for autodiscover
    2 DNS records were created for the 2 VIPs
    Clients use Outlook Anywhere (HTTPS) to connect to the CAS servers from external segment via a Palo Alto firewall, which also acts as a layer 3 router
    static arp was set on the Palo Alto firewall, with both virtual MACs pointing to the primary virtual MAC used by the NLB. 
    Observations
    1. within same segment - no issue accessing Exchange servers, even when one CAS node is offline
    2. external segment (via firewall)
    a. when both nodes are up
    outlook client able to connect to Exchange CAS VIP on 443, but will disconnect after around 30 seconds. Client will retry and the pattern will repeat
    Exchange CAS RPC logs shows client connections and disconnections to the outlook anywhere VIP address
    Firewall logs shows allowed traffic from client to the VIPs
    unable to complete profile creation
    b. with only CAS2 (CAS1 stopped/deleted from NLB cluster)
    no issues accessing Exchange servers, creating profiles etc
    c. with only CAS1
    same behaviour as (a)
    reinstalled NLB, but doesn't resolve
    deleted CAS1 from NLB cluster, and re-add. issue remain
    Q1. is teaming supported? Teaming is currently set to automatic mode, instead of specified Fault Tolerant
    Q2. are there additional settings we need to set or verify on the Palo Alto firewall, since the issue only happen to external segment? Thanks!

    Yes - I've been scarred with this for many years :(
    If it is just CAS 1 that is causing issues, then focus in on that.  The support statement for Win 2008 R2 is that NLB is still a 3rd party component and support may ask for it to be disabled.
    http://support.microsoft.com/kb/278431 
    Does CAS1 and CAS2 have the same NICs (firmware as well), driver, teaming software, and teaming config? 
    I also want to ask what the network team did for configuring the switch ports on the servers?  This will vary from vendor to vendor  - did they do the same config on both?
    Cheers,

    Thanks Rhoderick, issue still persists
    can you also help clarify what you meant by "configuring the switch ports on the servers"?
    thanks again
