Critical - Exchange is down

I was having a lot of issues connecting to exchange 2010 with EMC and EMS - lots of authentication, access denied errors - spent about 30 hours trying to resolve it and it just wasn't happening.

So, I set up a new server, installed Exchange 2010. Everything seemed to be fine but somewhere along the line mail stopped being sent out. It's getting stuck in the queue with error message: 451 4.4.0 Primary Target IP address responded with: "421 4.3.2 Service not available"

It may have been a change I made on the send connector? Anyway, I don't remember what I changed and I need to get this back up and running.

My goal was to install exchange on the new server, then move everything over and decomission old server, but, obviously not happening - can anyone help with this?

Ok, I actually fixed this myself - had to add the new server ot the send connector.

Would still like some assistance in moving everything over to the new server though. Any takers?

can you give us a bit more context?

where you moving from?
2003 or 2007 to 2010?
include public folders?

Sure.. I'm moving a lateral transition from a server 2008 with Exchange 2010 to a server 2008 with Exchange 2010. :)

Public folders included.

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

 
Jian An LimCommented:
the migration path looks very alike for exchange 2007 to exchange 2010


http://technet.microsoft.com/en-us/library/bb124350.aspx <-- make sure you repeat all the steps (replace exchange 2007 with your old exchange 2010

for public folder, you need to replicate them

also firewall changes and etc.


** i assume your operation is 1 server and not a complex organisation **

Ok, so Exchange 2010 is already installed. Looks like I need to go through the Client Access Server configurations, move the mailboxes, replicate the public folders, and adjust the firewall settings to forward to new server... sound right?

Yes, 1 server, not complex.

Thanks!

Only issue so far:

[PS] C:\Windows\system32>Set-ActiveSyncVirtualDirectory -Identity DC1\Microsoft-Server-ActiveSync -ExternalUrl "https://mail.bustechllc.com"
The operation couldn't be performed because object 'DC1\Microsoft-Server-ActiveSync' couldn't be found on 'DC1.bustech.local'.

what is the result of "Get-ActiveSyncVirtualDirectory"
Is it listing anything? Can you share the results with us?

> if the above is not listing anything...we need to run the command "new-activesyncvirtualdirectory"

Ok - I'm gonna run some updates and install Exchange SP1 first.

Results of get-activesyncvirtualdirectory:

Name                                    Server                                  InternalUrl
----                                    ------                                  -----------

Microsoft-Server-ActiveSync (Default... DC1                                     https://dc1.bustech.local/Microsoft-...

server3 is old server, dc1 is new one

e_aravindCommented:
In this case use the following command
Set-ActiveSyncVirtualDirectory -Identity DC1\Microsoft-Server-ActiveSync* -ExternalUrl https://mail.bustechllc.com

Reason
set-activesyncvirtualdirectory -identify dc1\microsoft-server-activesync(Default Web Site) -ExternalURL https://mail.xxx.com  --> should be the full command

Ahhh ok, great, that worked...

bustechllcAuthor Commented:
Ok... I made some changes to the firewall, forwarding port 25, 80, and 443 to the new server IP

Made a DNS change to redirect mail.bustechllc.com to the new server IP

Took the old server offline.

OWA doesn't work. Outlook doesn't connect - but I was connecting with a mailbox that was still on the old server. I'm not moving production mailboxes until I know this is working - ie we can get owa working with a mailbox that is on the new server.

Reversed the change and everything works ok.

I was getting some security certificate errors. Not sure where to go/what to do next......

Enable-OutlookAnywhere -Server:<CAS2010> -ExternalHostName:mail.contoso.com -SSLOffloading $false

Basic?

bustechllcAuthor Commented:
Ok... looks like we're well on our way. Got the new server set up, migrated mailboxes, mail is flowing in and out.. all is well.

Still need to:

Fix Certificate Errors

Public Folders - I created a new public folder database, and I believe I replicated from the old server but it appears that when I have the old server offline that I can't open the public folder. Any help please?

bustechllcAuthor Commented:
Sorry, this is becomign my scratchpad and hopefully the notes will be of use to someone in the future

Ok - Certificate was exported from mmc on the old server and imported into new server through mmc > Certificates snap in.

Opened EMC and imported the certificate to the new server Server Configuration > Right Click server > Import Cert.

After importing, select the cert and assign protocols.

Fin.


So... just the public folders issue now and we're good.

bustechllcAuthor Commented:
Ok, I fixed the public folders issue by confirming that a replication had taken place.

EMS > change directory to ExchangeInstallPath\scripts

.\MoveAllReplicas.ps1 -Server Server01 -NewServer Server02

Then in EMC > Organization Configuration > Mailbox > Mailbox Database > Properties

Client Settinsg tab > Change default public folders database to the new public folder database

Done.
