A director would like his PA to deal with all external emails that are address to only him and no one else in the company is a recipient.

Is there a way I can route these emails to his PA and not have them arrive in his inbox?

Exchange 2016

I find that a old exchange server is left in exchange organization. I guess this was left in previous migration from the si company. Is it possible to remove it ? The old Exchange physical server is no longer exist in our network.

Hi Experts

And forbidden them to manually archive their mailbox

Kindly advice
I'm looking at installing Exchange 2016 CU 6. Currently we are on CU5, but I have been hesitant to install CU6 because I have read about alot of different issues with that CU, such as no longer being able to access OWA or EWS. I haven't found any solid fixes any mention about these problems either. Has anyone upgrade to CU6 and resolved these issues. If so what was the resolutions, because I would like to upgrade since CU 6 has been out for a while now.
I renewed a Godaddy SSL cert and when I install the .crt that they returned the data on the website in IIS is updated however, when I go to the site and check the SSL cert it stil has the old date. I have restarted IIS on the server but, the date hasn't updated. What do I need to do to get the SSL cert date to cjhange on the site?
I'm working with vendor and we need to connect our app to their Exchange server smtp for the mailbox they provide us. They do not want to allow because smtp because it is configured for anonymous sending. How can I connect our app? Can I recommend that they add our public IP to the allow list? in addition lock the port on their firewall gateway down to out public address?
Hi Experts,

I moved from a mailboxdatabase in a dag group all users to a new database as we had a problem with backup VSS errors.
Now backup is running fine again and i want to remove the database from exchange , I did remove the replcation from that database in ECP.
Trying to remove the database now but it comes up with that there are still arbitration boxes left .
Boxes that ae left are :

[PS] C:\Windows\system32>Get-Mailbox -Arbitration |ft Name, Servername

Can i remove these mailboxes? i dont know if they are also used for other databases that are still left in our exchange envoirment?

We are migrating from Exchange 2013 to 2016 but when uninstalling 2013 receive this error:
This computer is a member of a database availability group (DAG). It must be removed from the DAG before you can uninstall Exchange

No DAG exists, if i go into ADSIedit.msc within CN=Database Availability Groups nothing exists either...?

Any ideas?

There is an existing 2007 in my domain. Can I install Exchange 2016 as a "new organization" in my current domain ? Should I need to create a seperate site (different IP subnet) in order to host the new orgainizatoin ?

When a user is created with a mailbox, will it ask for which Exchange organization to select ?

So we have a support account,
This being the domain within an On prem AD synched to Office 365.

Recently we purchased another company of which have a support address.

We have their domain incorporated in Office 365 and can add smtp addresses as aliases in attributes.

However I need an account
AD will not let me create as complains about same username.

And this support address then needs forwarded to a ticketing system and when I create a rule in exchange, the system obviously cannot find the

there must be a way to create this
We have Exchange 2010 and setting up hybrid to move all mailboxes and PFs to O365. After that is done can the autodiscover record be pointed to O365 so Outlook clients detect the new server and connect directly and the also change MX record to O365 for incoming mail to go directly to O365? At that point local Exchange would be shut down to make sure there is no email flow, free/busy, etc, dependency and then later on uninstalled. I know this may not be the Microsoft supported way but we are OK managing Exchange attributes via ADSI
I had one of my desktop support peeps build four new mailboxes.  by total accident, she created them on one of the default DBs installed when exchange is installed.  When Harvey hit Houston, we lost those databases and we were not backing them up since they weren't supposed to be used.  So, now I have four users on an orphaned mailbox database.

I tried to more them, but since exchange 2013 can't see the old database, the move is failing.

Is my only option to delete the mailboxes and recreate them?


Seem to be missing a step.
I have installed the SMTP service on the CA server and ensured that the service is running and set to automatic.
I have gone into my document library and enabled incoming email.
The email address shows the correct domain so I set the mailbox name to emailMe - and clicked ok.

Now I go to Outlook and I type the email address into a new email and instantly outlook is telling me that it won't be delivered as the recipient is not valid.
SharePoint 2013 and Exchange 2013 are both hosted in house on the domain and outgoing mail from sharepoint (e.g. alerts works fine).
What step am I missing - how does sharepoint tell exchange to add this address and where to relay it to?
I am the administrator of an Exchange 2013 with multiple Outlook 2013 clients running in a domain.
For absolutely no reason some my users start complaining, that they can no longer send any mails because Outlook reports, that their mail box exceeds the maximum limit.
This is very strange indeed, because if you look at these users in Exchange EAC the quota is unlimited???

Is there something I miss?     (other than some cash and good look)
The following update fails to install (on a Server 2016 VM running Exchange 2016):

Security Update For Exchange Server 2016 CU6 (KB4036108)

The application and system logs show nothing.  If I run the patch manually it just reports that installation "ended prematurely because of an error".

How can I troubleshoot this update installation?  Is there a log file somewhere?

Thanks in advance for any assistance
After my previous post¬ificationFollowed=197351224#a42291258
I tested and moved this to production.  things have gone terribly.  As soon as I stood up the second CAS server, all the clients started trying to talk to it, even though I had not made any of the load balancing DNS entries.  When I shut it off, all the client would not work at all!! (So much for failover cluster>:( )  At this point I am just tying to remove it.  I have uninstalled exchange and removed it from the domain, but all my clients are now not connecting at all.  Some one please help, I am desperate :(
I am trying to install Exchange 2016 on a Windows 2016 VM Server but the installation fails at step 10 of 14 with the error shown below:

My domain functional level is Server 2008 R2 and I have an Exchange 2010 server. I have performed all the pre-install steps and and prepared the Schema and AD. I tried creating a new VM and starting the installation again but got the same result. I have attached the ExchangeSetup log

The following error was generated when "$error.Clear();
          if (($RoleIsDatacenter -ne $true) -and ($RoleIsDatacenterDedicated -ne $true))
          if (test-ExchangeServersWriteAccess -DomainController $RoleDomainController -ErrorAction SilentlyContinue)
          $sysMbx = $null;
          $name = "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}";
          $dispname = "Microsoft Exchange";
          $mbxs = @( get-mailbox -arbitration -Filter {name -eq $name} -IgnoreDefaultScope -resultSize 1 );
          if ( $mbxs.length -eq 0)
          $dbs = @(get-MailboxDatabase -Server:$RoleFqdnOrName -DomainController $RoleDomainController);
          if ($dbs.Length -ne 0)
          $arbUsers = @(get-user -Filter {name -eq $name} -IgnoreDefaultScope -ResultSize 1);
          if ($arbUsers.Length -ne 0)
          $sysMbx = enable-mailbox -Arbitration -identity $arbUsers[0] -DisplayName $dispname -database $dbs[0].Identity;
So we are having an issue where everyone in company A is receiving a bounce back when emailing anyone in company B. company B migrated to Office365 a while back and they report no other companies are having issues emailing them.
DNS resolution for the domain resolves to Office365. The bounce back is received on mobile devices, OWA, laptops internally and externally for companyA. The server generating the bounce back is the old email server
I asked IT for companyB to check their DNS records for any stale records, but they assure companyA that no stale records are seen.

Thoughts on what else to check?

We are thinking of putting our Microsoft office apps in the cloud but keep our exchange Server in house.
Has anyone rolled this out and working this way.?
Advantages or pitfalls you personally have experienced.
We have Exchange 2007 and I want to enable Outlook Anywhere feature for the purpose of office 365 staged migration.
We already have a working OWA 2007 for the users and I have completed the following steps a, b and c

a) I had purchased multi domain SSL certificate with ( and  and have installed successfully on our exchange server.
b) I have installed Enable RPC over HTTP
c) On the EMC- Sever Configuration-Client access- I have Enabled Outlook Anywhere.

Our DNS and firewall is hosted by  external company . Do I need to ask them to create CNAME record for  to point to the same IP of OWA( Exchange Server)
Any help would be great, Thanks in advance

How to sync between outlook 2016 calendar  to Google calendar?
This will be wordy...trying to give all the info that I know to help out the experts.
We have converted from Ex2010 to Ex2016, we have hub in dmz.
we have a new cert from digicert-,,
Cert has been applied. mail is flowing fine, in and out.
When you open outlook you get a cert error- - the name on the cert is invalid or does not match the cert.
I know you can't assign a cert to a .local or internal server name anymore. so I'm not sure what to do?
something else that is very odd in our DNS. we have an A record x.x.x.11 (.11 is ex2010), If I change it to .15 (.15 ex2016 new server) email will not get to exchange- we get a bounceback message stating that the email is rejected due to content filtering. even if the email is nicely worded and formatted properly.
So 2 strange issues.
Last very strange issue...If I manually create an outlook profile- servername: ex2010, username and click check name the servername: ex2010 magically changes to ex2016 and the check name works and there is no cert issue.
I want my 90 users to not have the cert error, and not have to go to 90 workstations and manually recreate every persons profile.
