Hi all,

Due to the POODLE vulnerability and TLS 1.0 showing as enabled on one of our external scans, we were informed that we would need to disable SSL 3.0 and TLS 1.0 on our Exchange server.

Apparently, this wouldn't even be possible until Update Rollup 9 was released on 3/16/15:

Rollup resolves:

KB 3029667 SMTP is not transported over TLS 1.1 or TLS 1.2 protocol in an Exchange Server 2010 environment

After installing this update, SSL 3.0 and TLS 1.0 were disabled and the servers rebooted (cross site, same domain, two Exchange servers).  After resolving some issues with certificates that apparently broke as a result of the changes, we found that EWS was not working - the log full of these errors:

Dear All,

I added new exchnage server in my exsting exchnage 

(2Mailbox and 2 cas), after deployment i couldnt able to see my new server in ecp also server tab it is showing none

please find the below

please suggest me for fixing this

After a recent reboot of an Exchange 2013 server, I can no longer get into OWA or ECP. 

When rebooting, the server gave me the option to 'Update and Reboot' which I did.  It appears that CU9 was installed according to recent updates however I did not manually apply the update.

After reboot, all Exchange services and a few other services were set to Disabled.  Using another Exchange server I was able to determine what the startup type should be, set it accordingly and was able to get mail working however I still have some problems.

OWA will display logon screen but says 'bad request' after entering credentials.  ECP gives the following

I tried to uninstall CU9 but after reboot all services were disabled again.  Now that mail flow is working, I wanted to get some other ideas before experimenting and making things worse.  This appears to be an IIS issue but I welcome ideas, or better yet, solution, on how to get things working again.

Thank you.

Hello,

I run into a problem with replacing a exchange 2013 server and I wanted to ask you if you could help me.

I installed a new exchange 2013 (same build like the old one) and included it into the same oranization and domain. After I copied/changed the certificates, mailboxed and send connector, the clients connected well everthing looked good.

To test everything, I paused the main Exchange Server (VM). When the main Exchange Server is not accessible, I can't open ecp or owa (html error 500) anymore on the new Exchange Server. When I start the first Exchange Server again everything works like it should. 

Strange is, that owa and the clients however (outlook) works fine with or without the first Exchange server.

Do you have an idea?

Thank you

Frenz

Have a client we are moving from SBS2008 (Exchange 2007) to Exchange 2013. I understand the need for the legacy namespace for co-existence, problem is we don't have a second public IP address to point to it. The current public IP points to mail.company.com but is only used for OWA and mobile device access, the MX records are pointed to an off-site filter (Solar Winds), then mail is passed from there to the server public IP. Any ideas how to set it up without losing the OWA access and mobile device access? If I skip adding a legacy namespace to the 2007 server on public DNS but add it internally and point the mail.company.com public DNS to the 2013 server will the users still have access to their mailboxes on the Exchange 2007 server and will OWA redirect correctly to the 2007 box? Thanks.

I recently schedule an update from Exchange 2013 CU19 to CU21. I downloaded the CU and started the upgrade process. It failed trying to removed the previous Exchange files and I could not get around the error. Has anyone else experienced this issue. See image. 

My environment two dcs, one 2012R2 and one 2008R2, both with .net 4.7.1 installed. Domain level at 2008R2. My exchange is at CU15 with .net 4.5.2 installed. Is there a schema update? Do I haveto run domain prep? Is the steps, install .net 4.7.1 then run CU21? After installing 4.7.1 should I reboot first or just run the CU update immediately after?

If i look at the information posted above the are a few things missing, Server, GeneratingMailbox, PublicFolderDatabase andOrganizationId what are these values supposed to be, are they all needed and how do i set those values.

For the GeneratigMailbox i thought the value should be "SystemMailboxbb558c35-97f1-4cb9-8ff7-d53741dc928c" to be set by using this command;

Evey bit of help would be greatly appreciated.

The exact message:

There is a pending reboot from a previous installation of a Windows Server role or feature. Please restart the computer and then run Setup again.

Other posts say to remove:

HKLM\SYSTEM\CurrentControlSet\Control\SessionManager\PendingFileRenameOperations

But that key does not exist.  Needless to say, I have recently restarted the server after seeing this error.

Hi All,

I have two exchange 2013 servers and one witness server in my DAG group.

We use a 3rd party SSL cert for exchange and it was expiring, so it has been replaced. I have noticed I can only see the SSL on the primary exchange server.  When I  login to ECP and go to certificates I can select both exchange servers from the dropdown box, but only the primary exchange server shows the ssl cert. I tried to import the SSL but is says an SSL with the same thumbprint is already in use.

NOTE: Both servers host all roles.

If we fail over and the secondary exchange does not have the SSL, will outlook clients be able to connect, send and receive mail?

After a drop in service due to a cut in connectivity with the Storage. Users in three databases can not access the owa options giving error 500.
This occurs in only 3 bases, this server has 8 and when I move a user to another DB on another server the problem continues.
It is only solved when: Export the mailbox, disconnect the user's mailbox, create a new mailbox to the same AD user and import the data again.
I suppose there is a problem in the AD object and it is solved when I regenerate the mailbox.
If I do not find another option I will have to do this procedure with 300 mailbox :-(

The access to the mails by owa is normal without problems, only when they try to accede to the options to generate a rule, his signature or an absentee of office gives error 500

Any ideas?

Thanks in advance!



Can someone tell me the fix for this? I am installing Exchange Server 2013 in a Virtual Machine and keep getting the error message below on Step 8 of 15 of the Exchange 2013 installation. All prerequisites are installed.

Error During Exchange 2013 Mailbox Transport Role Install On Server 2012

  I was installing Exchange 2013 on Server 2012.  The server is not a DC, but is a member of a domain with a 2008 R2 functional level, and I was logged in as a domain admin.  There has never been an Exchange instance on this domain.  I got past the prerequisite checks, and the installer showed 15 steps, so I walked away.  When I came back, I saw this:
