How does autodiscover knows what URL to pass: internal or external

December 22, 2016, 3:16 pm

Dear

When an outlook client gets his configuration via autodiscover, autodiscover returns all necessary URLs for oa, owa, oab...
When you configured for each service an URL for internal and another one for external, on what criteria does autodiscover decides which URL it passes to the client: internal or external?

If an outlook client is been installed on a forest which is not the exchange forest, but the user logged on to the workstation is a user account that exists in the Exchange forest (over the forest trust) what URL will be send to the client: external or internal?

How does autodiscover and in turn the client knows to which URL to connect, external or internal?

Thanks for the feedback.

After accidentally deletion of the Default Web Site on IIS8, I have recovered the virtual directories of exch 2013 from powershell according to this https://technet.microsoft.com/en-us/library/ff629372(v=exchg.141).aspx. Everything on server works fine (ECP, OWA, Powershell...), and also the internal clients can use owa on their browser (the server is for intranet not conected to the internet). The outlook app cannot connect (I use outlook 2010). Can you help me?

thanks.

Autodiscover fails internally in Hybrid environment

December 23, 2016, 8:56 am

Hi,

We have a hybrid setup with Exchange 2010, Exchange 2016 and Office 365. 

We work with Outlook 2016. 

The problem is with users that have been migrated to the cloud and with internal Outlook clients. 

Externally, autodiscover works fine. On the testconnectivity webpage from Microsoft, there are also no issues reported. 

However, internal clients cannot connect. When I use "Test E-mail Autoconfiguration" I am prompted for the password but the result in the end is still "Autoconfiguration was unable to determine your settings!"

I am unable to see the last (probably most crucial) error because Microsoft has decided that the "Test E-mail Autoconfig" screen can not be resized! Thank you Microsoft!

As far as I could see, Outlook 2016 does not have an easy to find Autodiscover log file (like the olkdisc.log file in 2010). 

In any case I have posted here what I can see:

Can someone help out? Many thanks!

PS: When creating a local XML redirect to https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml it does seem to work (even though it takes quite a while with some time-outs visible in the autodiscover log).

OWA Not working for Linked Mailboxes

Hey Fellow Techs,

Wondering if someone could assist me with an issue we are having. 

We have an Exchange server in a resource forest (domainA) and 2 accounts forests (domainB and domainC). DC's running server 2016 in the accounts forests and 2012 r2 in the resource forest. Exchange server running on 2012 r2 as well. The domain trusts are in place and the linked mailbox users are all setup and working via Outlook. However when ever a user from domainB or domainC tries to login to OWA they receive a invalid user name or password error. Yes we are using forms based domain\user and still does not work. However any user in the resource domain (domainA) can log on fine. 

We have checked the protocol settings and the owa enabled flags but all look fine. 

Any help would be appreciated 

Thanks in advance.

I understand, that it first try to auth. without username, and then Again using username, but howcome it does this Again and Again?

I don't see this, on users running RPC over HTTP?

Outlook 2013 Exchange 2013 issue with two computers

December 16, 2016, 7:15 am

Hello all,

I have this really annoying issue that I cannot seem to pinpoint the cause/reason for it.  We manage a single Exchange server with around 300 user mailboxes.  This is affecting only one user.  Here is the scenario:

User has a desktop computer with Windows 7 Professional and Outlook 2010. User has also a laptop with Windows 10 and Outlook 2013. If Outlook on the desktop is open the laptop cannot connect to the Exchange server (0x8004011D present in Outlook when performing an Update Folder).  As soon as the desktop closes Outlook, BAM! Outlook 2013 on the laptop works without issue.

Steps taken so far:

  • Re-create mail profiles on both the desktop and laptop which also re-created OST files
  • Fully patch Office and Windows on the laptop
  • Tried using office 2010 on the laptop prior to Windows 10 upgrade and Office 2013 upgrade - same deal.
  • Disabled all interfaces except for WLAN adapter
  • Opened Outlook with the /rpcdiag flag to view connections which show it trying but immediately terminating it (like a blink of an eye kind of thing) until of course the desktop client is closed and then it makes and keeps the connections

I am open to any and all troubleshooting you all can provide.  Thanks!

Outlook 2010 can't Connect to Exchange 2013 and Offline Address Book download Failed

Hi,

  Recently, I install Exchange 2013 with the planning to migrate from Exchange 2010.  I had created a few test accounts to test the mail flow between both Exchange servers and externally.  Everything was working fine except that if the outlook client if configure without cached mode, the test account can't connect to Exchange 2013.  With cached mode, I can see the status connected to exchange, but unable to send email as both online and offline address book were unavailable.  I tried to perform the send/receive to download the offline address book, I get the error of object not found.  When I check the connection status, I noticed that the directory was disconnected.

  I had checked the outlook client setting to ensure that the encryption connection is checked, and also recreated the offline address book and verified that the generation was successfully.  I was able to access the url of the offline address book.

  Using Outlook Anywhere, everything was working fine as I'm able to browse the address book online. 

  Could anyone advise me, what could be the problem and if not, any place I could look for possible problem that cause this behavior.

  Thanks.

I have Outlook 365 thru work (Exchange server). Unable to recall any messages sent, even though the other user has not opened the email The client is open, but the email was not opened. Have had the problem, since Outlook 2007. This is only referencing emails that are sent thru the Exchange server. The other user(s) can do the the recalls, but I am unable to do so. Some help on this would be greatly appreciated, as our own support desk is unable to provide a resolution to this.

Stuck in a loop. "the name cannot be resolved. the connection to microsoft exchange is unavailable"

Hi there,


I am trying to set up my Outlook desktop client. It's an Office 365 environment (Enterprise E1 plan) and I am running Windows 10.


I opened the Outlook desktop client, and after 20 minutes of it hanging there "searching for the mail server" I gave up and decided to manually enter the information into the client. I located the server address and all other settings in my old laptop.


I am sorry I cannot recall which server *type* I specified out of the three options - I believe Exchange server, since we have Exchange Online - but whatever it was, I take it it was wrong.


By some brilliant design, I am now stuck in a loop and cannot get out.


Note: I have already tried some unhelpful advice given on other questions posed to Office365 support about being stuck in this loop. There they advised to find my Mail settings in the Control Panel and delete the user account.  This has done nothing but change the loop I am in.


What happens? I open Outlook, and am told:


"The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action." 


I click OK, and get the Microsoft Exchange settings window which lists the server name (which cannot be changed) and the user name, which matches the settings in my old laptop. I click "Check Name" and get "The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action." 


I click OK on that and then try "OK" on the Microsoft Exchange settings window and I am told, "Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Your profile is not configured."



I am online, clearly, I am sending you this message now. All my other co-workers are using Exchange and I see my mail in the browser-based client. 


Thanks in advance for any insight.

Outlook - Envelope icon doesn't disappear

Hi,
I've enabled the Envelope Icon in the system tray for new mails (http://support.microsoft.com/kb/292034/en-us).

If a new mail arrives and I open Outlook 2013, read the mail, the envelope doesn't disappear, even if there aren't any unread messages.
The only temporary solution is to right-click any Outlook folder with all read mail and then selectMark All as Read in the context menu (mentioned here: http://superuser.com/questions/335122/why-does-the-outlook-taskbar-envelope-icon-sometimes-remain-active-even-if-i-ha)

We are using Outlook 2013 with Exchange 2010 SP3.

Why isn't the envelope hiding automatically, after I read all mails? This doesn't happen always, but most the times.

Thanks
