Exchange 2013 audit logs

January 22, 2017, 12:25 pm

Hi,

recently I installed in my network exchange 2013. I noticed that the exchange won't write mailbox or admin audit log. I enabled them both from the powershell management tool, but still all the logs are empty (I enabled the audit logs for all the mailboxes and the admin audit log.

Moreover, I checked the folder statistics, and I saw that there is no audits folder. Why does this happen? How can I fix this, so exchange will write those logs? How can I check folder statistics for the admin audit log?

Thanks in advance,

Emma Hall.

EDIT:

I kind of solved half of the problem. I noticed that my index DB was corrupted, so I re-created it. After I've don't this, I could see my admin audit log entries!

But I still have the other half of the problem - I still don't have mailbox audit logs.

OAB Issues

January 31, 2017, 6:38 pm

We have completed are testing and worked out just about all the bugs we had to migrate from 2007 to 2013. The last issues that remains is the OAB. So if a user is on cached mode on 2007, then gets migrated to 2013, when they open Outlook they get a continuous prompt for their credentials. Running outlook /rpcdiag, it shows it is trying to connect to 1 of the Exchange 2007 servers. If after their migration to 2013 the user unchecks cached mode all work fine, re checking it makes the issue return. I am able to resolve this by either closing outlook and deleting the .ost file, or remove the profile and recreating a new one. The issue with this is we have 5000+ mailboxes and doing this for everyone is not ideal. I have made a new 2013 OAB and set it as default and all URLs for 2013 servers got to https://mail.domain.com/oab and 2007 server goes to https://legacy.domain.com/oab. Anybody have any ideas on what I could try?

Broken mailboxes after moving to new domain - Exchange 2013

Hello Exchange world. I have a weird issue that i seriously can't figure out.

Our domain is like thus:

ad.domain - top of the forest

grp.domain - sub tier

We are looking to close down our sub domain trees and only use the ad.domain one. My boss used a migration tool to move the shared mailboxes as a pre step before we move the users. Also he has created users in the ad domain. So they all have a grp.domain login and a ad.domain one. They all all still using the grp ones because the ad ones do not connect to anything.

The issue we are having is after he migrated the shared mailboxes (and went on holidays -_-), I am finding the shared mailboxes seems to randomly lost permissions for like 5-15 minutes. In outlook, it asks for credentials that don't work. However if I log in via owa I get an error message, but if I refresh 1-3 times it seems to regig the account.

Also, we moved one of the users from the old to the new and that mailbox is displaying the following error for 5-15 minutes 1-3 times a day:

X-ClientId: ITBW - 0CMD - T0PA - NEHW
X-OWA-Error: SDServerErr;Microsoft.Exchange.Services.Core.Types.MissingEmailAddressForDistinguishedFolderException
X-OWA-Version: 15.0.1347.5
X-FEServer: MX1
X-BEServer: mx1.ad.domain
Date: 27/06/2018 05:56:40

I'm at the point of manually deleting and recreating each account one by one however I thought about asking if anyone else know what is going on here.

Cheers,

Scylon.

P.S.

this is the error in owa for shared boxes:

X-ClientId: JGCS - GTBW - ZEQH - NAGBWXQW X-OWA-Error: SDServerErr;Microsoft.Exchange.Services.Core.Types.NonExistentMailboxException X-OWA-Version: 15.0.1347.5 X-FEServer: MX1 X-BEServer: mx1.ad.doamin Date: 26/06/2018 23:25:44

Is the DB corrupt?

I am doing Exchange migration from 2013 to Exchange 2016, but when I click Migration from the EAC I get the following error "A version mismatch was detected (Actual:6, Expected:5)." I have migrated the migration mailbox to Exchange 2016 and checked with get-mailboxMigration* -Arbitration, I can that it was migrated to Exchange 2016 server. So far I have 3 CAS and 5 MBX on Exchange 2013 and 5 MBX+CAS on Exchange 2016, what else can be done apart from moving the migration mailbox to Exchange 2016

Is it possible to mount Exchange 2010 DB to Exchange 2013? Actually I have Exchange 2010 but that vm is continuously showing errors and working very slow. So I created a fresh VM and installed exchange 2013 on it. Now I want to simply dismount DB from exchange 2010 and copy DB and Logs from that old server to new Exchange server 2013 . Then I simply execute mount command. Can it be done?

What is the search syntax when trying to filter recipients in Exchange Admin Center?

I'm hoping it's just an oversight on my part but, for the life of me, I can't figure out how to perform an advanced search. Interesting enough, when you start typing it provides tokens but there doesn't appear to be any wildcard options. As an example we have a multi-tenant environment, and I want to search for all those whose email address contains "contoso" -- Zero results.

I think okay, perhaps I should use the ellipsis to jump into the Advanced search dialog. Same results -- zero. Oh wow, there's that handy Help link in the top-right corner. That will set me on the correct path. *Click* oh wow, it takes me to a TechNet Library page titled "Recipients > Advanced Filter" but alas it is still waiting to be populated with content.

I've been hunting around but to no avail. It seems there clearly a push to use PS for any administrative tasks. As much as I'm on board with this, there is definitelybeauty is having a web-based console at my fingertips.

Perhaps we are expected to the same recipient filter syntax? -eq -ne -like

BULK SMTP RELAY ON PREMISE SETUP FOR CLOUD 0365 EMAIL

Hi,

We have Hybrid setup and we are sending almost 50,000 emails per day from our 15 application servers to our clients. The from address is static but TO: Address is dynamic for the client.

We want to remove our on premise Exchange servers and move everything to cloud. But what i understand the o365 receives smtp relay email 30 per minutes and 10,000 max.

Need a solution if we can decommission our exchange server and setup a windows 2012 R2 based relay service. Not sure what next, do i need to contact Bulk Mail service provider or something extra setup required.

Need an expert advise in my case for smtp solution to send email or if any third party software on premise installation can fix this. we want to send to our customer so no routing of email to o365 is must.

Thanks,

Farooque

We are using Exchange 2013 edge deployed in DMZ, so autodiscover message from Public is reaching Exchange edge, it is then refusing the connection on port 80 & 443. Does Exchange edge support Autodiscover ?

Outlook 2016 crashes at setup - Exchange 2013 and 2010 co-existing

I've had an Exchange 2010 server running with 2012 R2 AD servers with mail running fine, no errors.

I installed Exchange 2013, and I have internal and external OWA working fine.

I moved a 2010 mailbox to 2013 to test the connectivity of 2013. It moved successfully and I can access it with OWA.

So to test Outlook 2016, I setup Win10 w/Outlook 2016. Starting Outlook setup, it matches the logged on user immediately. 

When the setup is connecting with the mailbox on Exchange 2013, Outlook 2016 crashes. I have to remove Registry entries under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles\Outlook to get the install to run again. Same issue when it's run again.

Do I have to tell Outlook where to look for the mailbox since I moved it to 2013? Is autodiscover still pointing to 2010 - not sure where to find this information as no autodiscover are setup in DNS.

Not sure what I'm missing here!

Event ID 12014 - MSExchange Transport

November 18, 2017, 9:37 am

Microsoft Exchange couldn't find a certificate that contains the domain name mail.domain.local in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Send To Internet with FQDN parameter of mail.domain.local. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key

I could not solve the problem. what is the solution ????

Sudden High CPU usage

All of a sudden without any changes that I am aware of our Exchange servers have started running at max cpu like 80% percent of the time. We are on Exchange 2013 3 mailbox servers and 5 cas servers. All are running CU19. The meexchaneservicesapppool and msexchangesyncapppool are the major contributors. I am using ExMon to indentify the users who are using a lot of cpu. Is there anyone else out having a problem like this? I know that sometimes IPhone will get an update that can trigger these kinds of issues. Just want to know if anyone else is having a problem.

Hello,

I've been tasked with seeing if there is a way to export a list of  all external email address's which have been sent an email through our exchange server and to go with that list the person who sent the email from our organisation.

Hope I'm making this clear, is it possible?

For example something list this

joe@mydomain.com sent an email to blogs@externalemail.com

In a CSV format if possible also.

Expired Exchange Certificates - Okay to remove?

June 26, 2018, 11:30 am

We have exchange 2007 and are planning on moving to Office 365 in the near future. However our certificate just expired and I renewed it with this method: Get-ExchangeCertificate -Thumbrint "[thumbrint]" | New-ExchangeCertificate populating the thumbprint with the thumbprint of the expired certificate.

However when I went to assign the services i was warned that SMTP could not be assigned because our hub transport services receive connectors were using a different cert. That different cert is expired as well... like a year ago actually. 

The other issues is that I have to manually install this new certificate on everyone's computers. 

Would this workflow not break the receive connectors and make it so I don't have to install the certificate manually on pc's? 

1. Copy the certificate that is currently expired that the warning told me about.

2. Delete all of the expired certificates(there are like 5 or 6 of them) as well as the first new one I previously created and the one I copied in step 1.

3. Assign the IIS, IMAP, POP and SMTP services to the newest certificate ( from step 1)?

I am concerned that the Hub transport receive connectors will break. 

Thanks,

James

EDIT: here is the warning I am receiving.

WARNING: This certificate will not be used for external TLS connections with an FQDN of 'server.domain.com' because the
CA-signed certificate with thumbprint '977EF8E8E267A1066156B1A5F8C7CBCD12B05C67' takes precedence. The following connectors match
 that FQDN: Client LGMAIL, Default LGMAIL, SMTP Recieve, Word Press Internal test Relay, LG Pdf Relay, Prineville PDF Relay,
Hermiston PDF Relay.

Excahnge 2016 connectivity oddity

I have learned how to validate a Exchange server with Telnet, and have done so several times.  Recently while trouble shooting I have found some very odd behavior.  The ehlo command works fine, but the mail from:fsdfsd fails the first time, and then works the second time.  same for the rcpt to command.  I have repeated this a dozen times.  I checked the "Back Pressure" and all is well.  These are VM's, so there can't be a hardware problem.  What else could be causing this?
