Exchange 2013 - Outlook Certificate error

September 1, 2020, 3:13 pm

Well its not the 1st time I have changed certificate on Exchange.

Certificate from internal CA is being used. Yeah thats right.. its only intranet exchange environment.

Root Certificate of CA is installed on Exchange servers, CRL is installed, Certificate is installed with mail.domain.com and autodiscover.domain.com.
Certificate has Only IIS service enabled. Rest are not.

What I have noticed is, the default self signed certificate is still have IIS enabled. adding new certificate and associating it with IIS does not clear IIS check mark from self signed.

Is this normal behaviour? I dont think so.

OWA,ECP shows no issues. Outlook sometimes works, and later it through certificate error mentioning the name of Exchange server i.e., ExSrv1.domain.com, when viewing the certificate it show the correct certificate.

But it has been quite a while,...

Accept mail for another domain then forward

Good Morning,

I currently run two small businesses from one premises Unfortunately only have one inbound IP address and can’t change that until my contact expires next year.

I have AD domain services and exchange 2016 up and running for DomainA however I’m wondering is there anyway to have the exchange server in DomainA accept and then forward the emails for DomainB to that exchange server for processing?

I’ve done some searching online but only seem to stumble across posts for having multiple email domains on one exchange server.

The setup is as follows:

1 inbound public IP address

Unifi USG3 router with LAN one for DomainA and Lan2 for DomainB

DomainA
10.0.0.0 subnet
Server 2016 AD services
Exchange Server 2016

DomainB
20.0.0.0 subnet
Server 2016 AD services
Exchange Server 2016

Any pointers or guidance would be appreciated as I’ve got myself...

Expiring SSL on old - New SSL for new Exchange server question...

Pondered this yesterday... I'm migrating our on-site Exchange 2010 server to an on-site Exchange 2016 server. The SSL cert for 2010 is expiring in 21 days so I'm looking to get a new one for Exchange 2016 with some new/different DNS names on it. However.

We changed our main company name a while back, probably eight years ago now. We went from oldcompanyname.com to newname.com. In the old SSL cert I've got mail.newname.com, mail.oldcompanyname.com, autodiscover.newname.com and autodiscover.oldcompanyname.com to sort of cover for whatever. But .. moving forward, can I safely not have anything to do with oldcompanyname.com in a new cert? We very rarely get an email sent to oldcompanyname.com but I suppose it's possible. I still have DNS records set up to send mail., legacy. and autodiscover.oldcompanyname requests to Mimecast and from...

Greetings

I recently migrated a client over to office 365 E1, E2, and kiosk plans. 

The users are able to sign in to their emails with the cellphones, the webmail, and 3rd party apps on their computers but not with outlook. 

I have contacted Microsft and PAX8 support and they seem to be rather useless.... 

At this point im running out of options and might move the client to another platform like GSuite ---- id really rather tprefer exchange..... 

Does anyone have any idea what it might be?

User only receiving emails from Distribution groups not individual emails

Hi All, 

Have an issue that just sprung up, a user is only able to receive external emails and emails internally when they are sent to a group he is apart of. 

This is in an Exchange 2016 environment.  This seems to have just started happening today. He is the only one that has problems, I have tested with multiple users and everything else seems okay. No settings have been changed today on my end. I have confirmed through OWA that they are not going to Junk Mail, he did not set up any rules, he has mostly been on the road today. 

Thanks in advance for any help!

Server replacement & Software upgrade

Hey everybody,

Hoping to get some words of wisdom from you guys on an upcoming project I have to undertake for a good client of mine that has me on retainer for so many hours per week.

So here is the skinny on their current situation: Currently they have an old server running SBS 2008 (Microsoft Server Standard FE) that acts as their DC as well as their email server running Exchange 2007. Now I'm already aware of the costs for hardware and licensing they will be facing either way, so I'd like to stick with pros and cons of having Exchange in-house vs Exchange online based on your experiences.

I've finally got them game to get upgraded, as this current setup is has gotten so far behind.

Now at this location they've had a few different local IT guys come in and do work for them off and on, as well as a few things their more knowledgeable...

Windows 2012 & Exchange 2016 upgrade

We are currently running Exchange 2016 (on-site) on a Windows 2012 (non-R2) server in our VMware infrastructure.

Due to the limitations of Windows 2012 (TLS support and ciphers), we are planning to upgrade to Windows 2016 and Exchange 2019. (Please, no arguments about "go to the cloud", etc. It's not in our road map for another few years.)

The last Exchange upgrade (from 2010) we did was moving from one server to another, transferring mailboxes, redirecting spam filters, firewall rules, etc. and it was quite messy and took a weekend of migration work.

I'd like to avoid this this time around by upgrading the server OS in place (and afterwards, Exchange). The OS does allow the upgrade in place path from 2012 to 2016, but I don't know how nicely the IIS and existing Exchange install will follow along, upgrading the TLS protocols and cipher...

Exchange 2016 multi-domain scenario

We have 1 AD site, with 1 forest and 2 domains.  Domain A (first domain controller and E2k16 installation)and Domain B both have 2 domain controllers and 2 exchange 2016 servers.  

The problem is that some of our Domain B mailboxes intermittently attempt to connect to email.domaina.com instead of email.domainb.com.

I have read where you can use site affinity if the exchange servers are in a different site, but has anyone been successful in using the scp keywords in ADSIEDIT to assign a domain to an scp entry such as domain=email.domainb.com?

Hi all, 

I'm setting up a hybrid environment with pilot users. Able to send and receive emails to and from on-prem to Cloud. But can not see free/busy calendar. It only works within the cloud or within On-Prem. 

Anything related to AutoDiscover or Organization relationship object? How I can troubleshoot them? 


Can I have two autodiscover CNAMEs for onprem.xyz.ca and autodiscover.outlook.com?


Any suggestions? 
Thank you

Exchange couldn't send email externally.

Hello,

I've tried to migrate the mail server (Exchange 2010-server 2008 R2 Enterprise) from hyper-V to VSphere 6.7.0, when the VM powered on I was able to receive email internally/externally, send internally, however, Exchange couldn't send email externally. I culled the logs and tried a lot of things but couldn't get mail to send externally. Everything looked fine but mail being sent out seems to disappear into the ether without showing up in the logs. Had to revert to Hyper-V version.

Do I need to start/stop some services or it's something else?

Can you please help here?

Thanks

Transport rule to reject email if an email is sent to 2 specific email addresses

I have a user that switched email addresses from firstl@domain.com to fml@domain.com becuase the first email address was published and the user was getting a lot of junk. Now some senders are sending to both email addresses and this is causing problems because the original address is forwarding, causing all kinds of duplicates.

Is there a way to reject emails that have both addresses as the recipient? Such as if sent to both, then a reply is sent that the mail wasn't received because of sending to a no longer valid email address
