I am removing the one and only Exchange server (happens to be 2003 still) after users migrated to O365 without any directory integration whatsoever. No migration to newer Exchange onsite first, just went direct to O365 without any AD integration.

I am assuming I can just de-install the Exchange software off the server and it will remove any Exchange based directory integration information (directory still at 2003- dont ask why), HOWEVER, after the mailboxes were removed from the users, I have repopulated the EMAIL field (general tab of user AD properties) with the O365 email address in hopes that this info will remain after Exchange removal and LDAP will still return the info from this field once Exchange is out of the picture.

Can you confirm

Hi,
I have just been messing around with some SSL certificates on a server running Exchange 2010. For a short time there was no active SSL certificate connected to the servers domain.
Now I have re-added a certificate and all looks fine - also when I test the SSL via DigiCert.

But when someone tries to send an email to an emailadresse in the domain/on the server they get an error back saying "550 5.7.1 Your IP is on the Protected Sky block list...".

I can't seem to find any useful information on this 'Protected Sky block list'. The domain/IP is not listed on any other lists. I have tried sending mails from Gmail-account, Hotmail-account and other domains. They all get this error.

What to do?

We have on premise AD where AD accounts are synced through AAD sync to office 365.

we have mailboxes in office 365, no on premise exchange.

i have to assign E3 license to 1 user in office 365 who is set to blocked.

if i check under active users .

i see his AD account is disabled, if i enable his AD account i can assign license
and his amilbox will be created. once his account is licensed

and then if i disable his AD account, what will happen to his mailbox

he has not joined yet and for security reasons i need to keep his AD account disabled till he joins next week

so will his mailbox stay or be in deletion state.

as i would like to enable his account once he joins next week

I have an executive who is being bombarded daily over the weekend with emails that are verifying his registration into many different newsletters, wordpress sites etc.  He did not sign up for any of these.

It appears that it is a cover up to possibly hide some financial transactions that they were trying. Someone did at one point somehow get into his Amazon account and attempt to order something.

We have enabled 2factor authentication for amazon and changed password, but now the question is ....can we stop the hundreds of emails that continue?

I am now blocking most foreign languages, which filters some.  But still hundreds make it through.

Any way to stop this other than changing email addresses?

Any thoughts are appreciated.

Hi,

We are facing very difficult situation at the moment. let me explain in detail.

Problem 1:
We are running Exchange 2016 server and  Domain controller AD on two separate VM's.
Last night, we faced disaster and our Hyper V HDD was crash. We trying everything but its totally crash.
We have Exchange 2016 VM backup but we don't have AD VM backup.
Please let me know how what will I do at this situation. If I created new AD with same domain name so I believe I need to rejoin exchange server with new AD.
What will happen with current mailboxes. They will work like same way that they were working previously.

Problem 2:
As i explain above our Hyper V HDD was crash so our three RDSH servers and their AD (Its not same AD as i explain above, different domain name) also down.
Again we have RDSH servers backup but we don't have AD backup so i guess I have to republish all the apps again.

Please let me know how to resolve these problems. Both are related to AD's. One for Exchange 2016 and other for RDSH server.

OS: Windows server 2016
Exchange: Exchange server is 2016

I have an exchange issue migrating to office 365. Well Microsoft sent me an email to run the following command but it renders this error. I have not heard from them all weekend. Can someone help me running this command? The database is not in the default location. Its on the E: drive.

Microsoft Instructions:
Add the Extended-Rights permissions "Receive-As" to the mailbox database.
Eg: Run the following command in the Exchange Management Shell:
Add-ADPermission -Identity "Mailbox Database 201312345678" -User "AdminAccount" -ExtendedRights Receive-As
Replace the “Mailbox Database 201312345678” with the actual name of the mailbox database and the "AdminAccount" with the account you are using for the migration.
Once done, STOP the migration batch, remove the mailboxes that failed from the migration batch and START the migration batch.

error:
C:\Windows\system32>Add-ADPermission -Identity "Mailbox Database MDB02" -User "MYUSER" -ExtendedRights Receive-As
Mailbox Database MDB01 wasn't found. Please make sure you've typed it correctly.​

Hello, I'm trying create a new send connector in my exchange lab environment however I get a 451 4.4.0 error message before it even reaches my smarthost account.  I've tried reviewing the trusted certificate and recreating the send connector via the shell instead of gui but both gives me the  same error.  The only way my emails goes out is if I re-enable the original send connector with the original exchange server in it, if I keep only the new exchange server in the original send connector it doesn't work, so I've at least narrowed it down to the new server I just built.  I've reviewed both send connectors too to see what is different and I can't find anything.

The setup is two exchange 2010 servers both on windows 2008r2.  My lab practice is to migrate to a rebuilt exchange 2010 and decommission the old one.  I've successfully migrated all mailboxes but trying to get only the new exchange 2010 server to send successfully to my smarthost isn't working so I can't continue to decom the old.  Any ideas what else I should try?

Verbose logs keeps showing my this as well:
"UntrustedRoot,Chain validation status"

Message Tracking logs Error Message:
"The last attempt to send the message was at 4/21/2019 11:50:12 AM (UTC-05:00) Eastern Time (US & Canada) and generated the error '451 4.4.0 Primary target IP address responded with: "454 4.7.5 Certificate validation failure."

CEOs need to know what they should worry about
CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.

I'm looking for a tool to take an existing domains user objects, groups, and contacts export their info and re-import them into a new domain. There is an existing Exchange 2010 environment too, and I would want the tool to bring over the more critical aspects of those attributes too (like alias, proxyaddresses etc.) Huge bonus would be if it handled legacyDN to X400 in the proxyaddresses.

Anyone know of anything like this? I know I can do it with scripts but a tool seems less error prone. Best option I've seen thus far is this, and others similar, but they make no mention of exchange related attributes: https://www.activedirectoryexport.com/

Instant searches in Outlook 2016 for our RDS users (not using cached exchange mode) are not displaying complete results.  If we search for mails we can see in the inbox from the past week, they do not display. As a test I connected to the RDS Farm and the same happens to me; when I switch to Cached Exchange mode--which we wouldn't do for the 150 RDS users--it works fine.

The button for Indexing Options under File - Options - Search - Sources is greyed out for everyone having trouble.
We do have the following registry key in place: HKLM\SOFTWARE\Policies\Microsoft\Windows\Windows Search PreventIndexingOutlook has a Value of 1.  I changed it to 0 and symptom persists.

We have a contractor working with us and we setup our email so that his outside email receives our department emails.
But we noticed that when he replies to one of our emails, we see this line in his response:
The actual sender of this message is different than the normal sender. click here to learn more

Is there a way to have this not show up when the contractor replies to our emails?
We are running o365 and exchange 2013

I need to find the log that contains all the connections and inbound email that was delivered for exchange 2016.  I've been unsuccessful so far finding this log.  It is possible it is not enabled.

Dear experts

We have exchange 2010 sp3 and we need to enable the archiving for our mail boxes
So I did enable the archiving on one mail box for test
And I created a retention policy for the test I configured that any email older more than one day will be moved to the archiving mail box
The test work very well but I noticed that all emails which used to be organized in different folders under the inbox Like for example ((emails form IT – emails from HP – email from expert -  private – etc.))
All moved to one folder
So in that time I thought if I will configure such settings for our 800 mailbox and set for example
Retention policy that any email older more than two years will be moved to archiving

And as I know every single user in our environment has his own folder structure
Some of them spend days or even month to organize them in one step I will destroy this for them. so they will kill me
My question how can configure a global email archiving policy for all our mailboxes
But at the same time avoid such issue

I know I can just enable archiving and let the users move the old emails as they like to the archiving box

But I want to know if I can configure a global policy but will not destroy folder structure for every user

Thanks

Hello, I have a Exchange 2016 running on Server 2012 standard Edition.  All is running well we had our exchange system originally setup with a mydomain.net mailboxes because the .com was taken, but later we purchased the .com and I added it to our system.  I setup a alias in everybody's account and we receive the .com just fine, but any reply's still say coming from the .net domain.  How do I get everybody's outlook to say the mail comes from the .com email address without deleting all the accounts and adding back as a .com.  eventually we will probably do away with the .net but I don't want to have to delete copy mail etc... for 200+ email accounts to a new .com since I am lazy lol.  Hopefully there is a easy fix so you can just pick the default outgoing email account in outlook.  Right now we don't use any accounts in a AD environment just on exchange email with outlook and owa access, plus on smart phones.  Any help or suggestions would be greatly appreciated - Bill

Hello,

I have a question about extreme Exchange disaster recovery plans :-)
e.g. Exchange server crashes and this kind of  server recovery  is not possible:
https://www.stellarinfo.com/blog/setup-m-recoverserver-switch-exchange-server-2010-2013-2016/ 
The only way is to install new exchange server and configure new mailboxes for AD users without
mailbox migration,extract pst from old server .edb(or from client outlooks)  and import pst to new exchange  server mailboxes.
What would be migration steps in this extreme case?

Thank you

Autodiscover is not working for Exchange 2013 and I need it to so I can migrate the mailboxes to O365. OWA is working, however. I cannot create the endpoint connection in Office365. I cannot even setup Outlook offsite/onsite to connect to a mailbox. Somehow their mailboxes are still working for those that are currently setup.

What should my cname record be for external autodiscovery with EXCHANGE 2013?
Network Solutions gives these options..
1) alias
2) TTL
3) Other Host

Host should be autodiscover.mydomain.com or mail.mydomain.com? And what should be the alias?

Everything Exchange admin shows mail.mydomain.com

We installed an New Exchange Server 2016 CU12 in and AD Environment and the previous email was GoDaddy Workspace IMAP Email.
We have Large Sub-Folder user that we imported all her IMAP PST in to Exchange and all her Sub-Folders are showing up in Outlook and OWA,
The User added their account to their iPhone and the folders showed up at first and now they have all went away, the sub-folders still show
current on Outlook and OWA.
Is anyone familiar with how to resolve the Sub-folders syncing and showing back up on the iPhone.
They are using the Microsoft Outlook for IOS APP.

We had our external  emails coming into our exchange system going  to one users email because someone deleted a policy for our spam filter. So my question is, is there a way to take the emails from that users mailbox without forwarding them and send them to all of the users correct inbox so that they see them as emails that should be in their inboxes?
Not sure if there is a way to do this via exchange or does it have to be done by taking control of each users mailbox and then put their emails back into the inbox?

I have to restart the information store service to mount the database.
What I am trying to do is move mailboxes to a new database to defrag database.
Not sure if the move is causing the database dismount or the dismount is causing the move to fail.
