Mail can't reconnect to Exchange 2013

My company has recently upgraded to Exchange 2013.
Mail connects OK with the new server and everything seems fine; however, if I leave my Mac, when I come back, Mail reconnects automatically to iCloud and gMail, but it remains "forever" (over 20 minutes) trying to reconnect to Exchange.
I've learned the trick of switching my WiFi off and and then on again which makes Mail connect instantaneously to Exchange, but this is a workaround. This happens with all WiFis, so it doesn't seem to be a problem with a specific WiFi network.
Has anyone experienced the same problem?

Back up all data.
Unlock the Network preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Cllck Advanced, open the DNS tab, and change the server addresses to the following:
8.8.8.8
8.8.4.4
That's Google DNS. Click OK, then Apply.
Test. Any difference?
Notes:
1. If you lose Internet access after making the above change to your network settings, delete the Google servers in the Network preference pane, then select the TCP/IP tab and click Renew DHCP Lease. That should restore the original DNS settings; otherwise restore them yourself. Remember that you must click Apply in order for any changes to take effect.
2. I don't use Google DNS myself, though I have tested it, and I'm not recommending it or any other DNS provider; the server addresses are offered merely for testing purposes. There may be privacy and technical issues involved in using that service, which you should investigate personally before you decide whether to keep the settings. Other public DNS services exist.

hi ALL
OUtlook 2013 can not connect to exchange 2013 after exchange maibox member of DAG failed.
Exchange environment contains 2 Exchange Mailboxesserver ,( one Failed , virtual Machine)

please support

Hi,
According to your description, I understand that Outlook client cannot connect to Exchange server 2013 while one member of DAG failed.
If I have misunderstand your concern, please do not hesitate to let me know.
I want to double confirm whether all account store in MBX1 experience this issue, users in MBX2 works fine.
Please run following command to double check the database status:
Get-MailboxDatabase –Status | select Name,Mounted,MountedOnServer
If it works in OWA, the issue may be related to Outlook side. Please run “Test E-mail AutoConfiguration” and “Outlook Connection Status” to get more details, expecial the setting of proxy server, it’s more helpful
for further troubleshooting.
Additional, please try to recreate a profile for testing. Besides, please move active DB back to MBX1.

Outlook 2013 can't communicate with Exchange 2013

we're just finishing migration to Exchange 2013 and found some Outlook 2013 clients (migrated from Exchange 2010) can't communicate with Exchange 2013. even if i recreate the Outlook profile.
what worked is to reinstall Office 2013. just want to get ideas why a reinstall fixed the problem.
same outlook proxy is there in the account settings.

Hi,
What was the symptom that Outlook couldn't communicate with Exchange 2013? Could you please detail this a bit?
If the Account Settings are completely same before and after the reinstallation, we can say the cause is not on the Exchange side. While I can't guarantee the root cause based
on the provided information. A reinstallation fixes the corrupted or missing components/files in Office, but it's hard to say what has been fixed during the reinstallation.
If you still have some Office 2013 clients that have not been reinstalled, try to run Microsoft Office Configuration Analyzer Tool to quickly identify problematic configurations in Outlook:

Outlook can't connect with Exchange 2013 after migration from Exchange 2007

<style type="text/css">P { margin-bottom: 0.21cm; }</style>
Hello,
recently we've done a Exchange 2007 sp3 to 2013 sp1. Users can conect perfectly with OWA and with his iphone clients.
But the problem is they can't connect from his Outlook clients (2010, 2013), both internaly and externaly. Always fails with the message: The Connection to Exchange it is not avaliable.... Can't resolve the name of Exchange server.
To try to resolve it we've done:
- Check Outlook anywhere configuration en EAC: it is configure with and external url mail.company.com and internal server.domain.local. The security is the default Negociation, but we've tried all.
- Check the internal dns, there are records for mail.company.com and exchangeserverdomain.local pointing to the exchange local ip. Also there is a public zone company.com with the record mail.caompany.com pointing to the exchange local ip. Also we've made
records autodiscover.company.com and autodiscover.domain.local pointing to the exchange local ip.
- In the public dns from our domain there is the record A and MX pointing our public ip. There aren't any record Autodiscover but we think that the manial conection should work.
Check certificates: we've made a new self-signed certificate including all this internal and external domains and for all services.
- Check Outlook Anywhere block: we've cheked.
Currently server state:
- Old Exchange 07 server can't start, it was in very bad state and we achieved migrate the mailbox to the new server, after that we tried to uninstall, but it crashes with a public folder replication error. We got uninstall all the roles
unless the mailbox. After a restart it can't start.
-The new Exchange 2013 looks great, there isn't any trail of the old server, or we haven't seen anything in the EAC or shell.
I paste below the result of Microsoft Remote conectivity analaizer, with Outlook anywhere test. It is clear that there is a problem with that.
Sorry because the test is in spanish and I translated it with google, from here I only can access the tool in spanish.
We continue to try to resolve the problem.
Thanks to all in advance!

External Mail Flow not coming into Exchange 2013 Server

We just finished migrating from Exchange 2007 to Exchange 2013 and when I disable a certain receive connector on Exchange 2007 we stop receiving external emails. I have reviewed all of the Exchange 2013 Receive Connectors and everything looks to be fine
but the server does not get mail flow. If anyone could assist with this issue that would be great.
Thanks,
Ryan

Hi,
According to your description, all your inbound mails cannot be received in your Exchange 2013 server after you disable a receive connector in your Exchange 2007 server. If I misunderstand your meaning, please feel free to let me know.
If yes, since your MX record has been configured properly for your Exchange 2013 server, we can begin with checking the A record for the Exchange 2013 server and confirm if all external mails cannot come in your organization. And we can depend on the following
troubleshooting to narrow down the mail flow issue:
1. Check the NDR information if there is NDR.
2. Check Telnet to test the mail flow:

External outlook clients can't connect to Exchange 2013

Currently running server 2012 r2 and exchange 2013 sp1...
Internally everything works fine, clients can also connect externally to owa/ecp. However when using an outlook client they are unable to connect. This is my first experience with exchange 2013 so I am at a loss. What steps should I be following to get this
working properly? Or if anyone has some suggestions to get more information I can do that as well.
Thanks!

Iphone user can't connect to Exchange 2013

Hi there,
i have Exchange 2013 on Windows 2012, PKI and certificate installed.
I have 4 users that can (must) connect to the server through iPhone. It works for all, except for ONE (the boss :-X)
I deactivate the mailbox, recreate it without import old mails. It still don't work.
Any idea?
Thanks.

Yes it's the first time on Exchange 2013.
Yes they have different OS.
The server just been installed so it never worked.
BUT I SOLVED MY PROBLEM with this article:
http://technet.microsoft.com/en-us/library/dd439375(v=exchg.80).aspx It concerne Exchange 2003 and 2010 but it worked for my configuration: Windows 2012 and Exchange 2013 and no error HTTP 500.
Actually my user is member of Administrators group and the inheritance is deactivate. I activate it and it's work!
Thanks to me and thanks to you for your answers!

Outlook 2013 can't connect to Exchange 2013 SP1

Hello,
I've already asked that question on Exchange 2013, now I'd like to ask it again in regard to Exchange 2013 SP1.
The question i s very easy: suppose I have just installed Exchange 2013 SP1 (in a Win2012 R2 domain) with three mailboxes (user1, user2, user3). I can successfully run ecp and owa for all users...
...but when I'm starting Outlook 2013 and trying to set up a profile manually, for example, [email protected], Exchange 2013 Sp1 keeps saying "Outlook can't log on...The name cannot be resolved."
In Exchange 2013 this could be fixed by adding the server's ip address to its Hosts file, but I thought it was a bug and it would be corrected later or sooner... Now the same problem with Exchange 2013SP1...
Would anybody please tell me is there anything special I must do to connect to Exchange 2013SP1 via Outlook 2013 (not Outlook 2013SP1 - without MAPI over HTTP)??? If yes what articles can I read about it?
Thank you in advance,
Michael

Hi,
When we automatically configure the account, Autodiscover service will help Outlook find the new type and we don't need to run the command to get the mailbox GUID until we manually configure the profile.
For more information, you can refer to the following article:
http://technet.microsoft.com/en-us/library/bb124251(v=exchg.150).aspx
"Through the Autodiscover service, Outlook finds a new connection point made up of the user’s mailbox GUID + @ + the domain portion of the user’s primary SMTP address."

IPhone 7 & 8 can't connect to Exchange 2013 CU5

I am getting call from users with iPhone and iPads that can't connect to our Exchange 2013 server. They get a error that the server can't be found. I can take the same account and run Microsoft online connectivity test and it passes. They don't have problem
with Outlook. Just the iPhone and iPads.
Matt Stehouwer Michigan State University

The error message I get is Exchange Account “Unable to verify account information”. This appears after the first screen that I guess you would call the autodiscovery screen if I click on that I am left on the auto discovery screen until I click cancel
I don’t advance to a screen that allows me to type the server or anything. I did the first time or two get the advanced setup screen that allowed me to type in a server but after that It wouldn’t take me to that screen again.
Looking at the cert idea.

Large Mail.que database in Exchange 2013

[Background]
Since Exchange 2013 is released, some user may come across the following situations:
The space of disk C is used up.
The transport service stops processing messages.
The Mailbox server is crash.
In this case, the issue can be resolved with checking with the mail.que file which is in the following path on the Mailbox server:
C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Queue
[Symptom]
The Mail.que file on all Exchange 2013 servers grows very large and it’s even over 20 GB.
[Cause]
It’s a by design behavior.
Different from the previous Exchange server, Safety Net which has the same function with the Transport dumpster in Exchange 2013 takes up the volume of the mail.que file and
it’s the feature which is responsible for the large size of the mail.que in Exchange 2013.
And here is a reference about the feature Safety Net in Exchange 2013:
http://technet.microsoft.com/en-us/library/jj657495(v=exchg.150).aspx
[Workarounds]
1. Allocate large space for the Exchange 2013 installation or increase the volume for Exchange 2013.
These articles will also provide further detail of size calculating:
http://blogs.technet.com/b/exchange/archive/2013/05/14/released-exchange-2013-server-role-requirements-calculator.aspx
http://blogs.technet.com/b/exchange/archive/2013/05/06/ask-the-perf-guy-sizing-exchange-2013-deployments.aspx
(See section: “Transport storage requirements”)
2. Moved queue database to another drive by using
Move-DatabasePath
3. Reduce the SafetyNetHoldTime and MessageExpirationTimeouton values to one day (default values are 2 days). And these commands can be in use:
Set-TransportConfig SafetyNetHoldTime 1.00:00:00
Get-TransportService | Set-TransportService -MessageExpirationTimeout 1.00:00:00

The client has a pair of Axway mailgateway appliances (Tumbleweed). We can Telnet between the exchange 2013 servers and the Axways. There is a firewall between these mail gateways and the exchange servers and the following ports were opened - 25,443,465,995,110
I used the existing send connectors from 2007 and just added the mailbox servers to them. I created 2 new receive connectors to match 2 specialist 2007 connectors.
But I still can't send mail. Any suggestions where next to check?

Hi Tony
Based on the protocol logs error looks like there is connectivity problem between Ex2007 and Ex2013
First you can try dropping an email through Telnet from Exchange 2013 to Exchange 2007 to see the message failure happens at which transit.
You can add the IP address of Exchange 2013 in Exchange 2007 default receive connector and vice versa.
Restart the transport service and try sending an email from exchange 2013 to Exchange 2007 and see the results
Also you can try creating a dedicated receive connector for Exchange 2007 in Exchange 2013 and vice versa if the above step does not work
Also try disabling the firewall and see if it helps.

Can we connect Outlook with Exchange 2013 with the default Self-signed certificate?

Hi,
the question is very simple, but after several days searching in this forums and in the web I have not been able to find a definitive answer YES or NOT. I know that Self-signed certificates are not for a production enviroment and only for labs and we must
purchase a third party certificate or get one from a internal CA.
Anyone can answer this question with no doubt?
Thanks in advance!

Hi Abhi,
I wrote this question because in a recent migration to 2013 from 2007 we've found with this problem: you can view it in the post http://social.technet.microsoft.com/Forums/exchange/en-US/1ddd1e81-1061-4461-95dd-13de653ef8fe/outlook-cant-connect-with-exchange-2013-after-migration-from-exchange-2007?forum=exchangesvrdeploy.
Also I have installed a new exchange 2013 in a lab enviroment and I also have unabled to connect from a Outlook 2013. The problem is the same Outlook is unable to detect the exchange server. Many people in this forums told me that have to be a certificate
problem and for that I posted this question. Honestly, I don't know how to do for Outlook can be connect with Exchange 2013. I don't know what I'm doing wrong.
Anyway thanks for your answer.

Exchange 2013 MB/CAS integration with legacy Exchange 2007 CAS/MB/Trans server

Hi All,
I have an existing running Exchange 2007 SP3 RU13 server acting as MB,CAS,Transport using a Barracuda SPAM for SMTP (MX Record is assigned to here), and a TMG2010 server performing all ActiveSync, Outlook Anywhere, and OWA connectivity.
I have built a new Exchange 2013 SP1 server that will (for the meantime) act as a MB & CAS server only.
I successfully migrated a testuser mailbox to the new EX2013 server from the EX2007 server. The problem is that once migrated, OWA and Outlook can't access the mailbox.
OWA form our URL gives the message: Outlook Web Access is currently unavailable. If the problem continues, contact technical support for your organization and tell them the following: No Client Access servers of the appropriate version can be accessed from
the Internet
If I run OWA from the EX2013 URL it works ok, but not for MBs on the EX2007 server.
I tested this configuration in a VM lab and it worked ok. All I had to do was move the mailbox, then run Outlook. Outlook automatically found the new server and opened the MB.
Basically what I need to do is move all our existing MBs from the old 2007 server to the new 2013 server. I want to continue to use the exisiting transport/CAS/EDGE services on 2007 without having to rebuild both the internal and external comunications
infrastructure at the present time.
How can I get the EX2013 server to act as the MB server for the EX2007 communications infrastructure?

Hi,
Please try to create a new user on Exchange 2013, and send/receive email via both Outlook and OWA to test whether the Exchange 2013 mail flow well.
If Exchange 2013 works well, please try to bypass the TMG on Exchange 2007 for a little while for testing.
Additionally, we can use CAS 2013 URL to proxy/redirect previous CAS, or publish both CAS 2007 and CAS 2013 to be internet facing server with separate URLs, as Ed suggested.
Thanks
