Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

There should be a log out option here under the email address. I only took one action and cleared the cache on Fire Fox earlier today.

Hi Experts,

I have to migrate migrate several mailboxes from DOMAIN A to DOMAIN B. Cross-Forest.
The user will stay in DOMAIN A but the mailbox is migrated to DOMAIN B.

We have nearly 200 mailboxes to do.
But in the meantime I have to test this.

How can I test the mail flow ? The MX Record is still showing to DOMAIN A.

Do you have any ideas ?

Exchange 2013 Standard Server environment with a single server.   Since installing CU23 in November we've had numerous mailboxes quarantined which in turn has dismounted a couple of mailstores randomly and throwing them into a dirty shutdown state.  Luckily the "fix" is to just run a soft repair which commits the logs and the database will mount.

As this has happened in only two of our five databases we have attempted to move mailboxes out of the questionable two into the other three but the migration batches, I have one batch for all the mailboxes in Store1 , that says it took 6 hours to run, status is Completed, but when you look at the mailboxes they're still in the original store.   Another time I tried to move one mailbox from Store1 by doing a migration batch in EAC, it runs for about a minute then completes.  It says 'Completed', Total 0 Synced 0 Finalized 0 Failed 0.  

Not sure where to go , i want to get rid of the two poisoned mailboxes but I would need to first export the mail which i can't do if their quarantined and they don't stay out of quarantine for more than ten minutes.

Dear Experts
We are in process of implementing on-premise exchange enterprise server, as our userbase is lesser than 25 we are installing following 1 and 2 roles in same server which is behind the firewall
1.Client Access services -
2.Mailbox services
Now please suggest should we have setup one more windows server in DMZ and install Edge Transport role here.
We have also procured barracuda email security on-site appliance.
Please suggest does the Edge Transport role to be setup in DMZ by retaining above 1 and 2 behind the firewall and in our design barracuda email security appliance exists hence Edge Transport role not required, please help in the design, thanks in advance.

Exchange server with several domains due to business name changes and several mergers over the years. My question is how to configure incoming email to show up in the users Outlook inbox depending on which email (domain name) they're sending to. For example, user@domain1.com was the default format. Over the years the names of the business changed to user@domain2, later user@domain3.com. I'm now getting ready to make the default domain @domain4.com. I've configured everything, tested and email is working fine. I changed the default domain to @domain4.com.

Is there a way to have the original sent to email show up in users inbox. For example, if I send an email to user@domain1.com, user@domain2.com, or user@domain3.com it always shows up to the end user as coming from user@domain4.com. The end user would like to know which email the sending is sending to rather than receive all emails appearing to come from the default domain (@domain4.com).

If someone manages to compromise your user credentials/account via a phishing email (office365 email account in this case) what is there typical objective(s) in doing so, and how would they typically follow that through to the next stage. I would have assumed if there target would be to steal emails they would not just casually start forwarding them on to an external address?  Trying to determine what they may or may not do if they do get a victims credentials would be interesting. there must be something in it for them but to determine what that is and how they execute 'phase 2' once access is achieved would be most useful,

We are going to to move away from Enterprise Vault and use Exchange Archiving. We use Exchange 2016 on premise. We are looking for design advice on where to place the Archive Databases. Should be run them from their own dedicated servers or should they be co-located within the servers that are currently running the mailbox databases? we are looking for pro and cons of the two different models is on more efficient the other while handling the connections maybe by splitting the DBs now the users are connected to multiple servers rather than just the one from which they are running their primary mailboxes?

Thoughts? or field experience on this topic?

thank you!

I'm dealing with viral emails that are from different email addresses and networks but are using the same "display name".

I'm looking to see if there's a way to block mail by the senders "display name" not email address

The mail server is running Sendmail under Linux

I know I can setup procmail rules, but for those to work the message needs to be accepted for delivery, however the end goal is to block the message before it's accepted.

ClamAV does detect the messages and when it does they're blocked however when a new version of the infected file is used it takes a couple of days before an updated signature detects it.

Client PC's are protected with AV which is detecting and blocking however stopping them entirely would be nice.

Currently my "new" version of outlook creates emails like this:
badI would like my emails to look like the old outlook:
goodIn other words, I don't want that DOT with my initials inside.

I want the "To", "From", etc to line up on the left.

Hi, our utility company sends large batches of emails to our customers (bill notifications) and we are having an issue where after ten minutes it will stop sending them. How can I increase the time limit on this? We have an Exchange 2013 hybrid environment and we route the traffic through the on-premise Exchange 2013 server .. if there is a cloud options, I'm interested in that too.


Thanks

Hi!

I am migrating Exchange 2010 (runs on Windows Server 2008) to Exchange 2016 (will run on Windows Server 2016) but pre-requisite keeps failing at extending the Active Directory Schema.

Running an on-prem Exchange 2013 environment and wondering how to give another user read only access to someone else's email account via the Outlook desktop application? We dont want the user to delete any emails from that other users account.

I heard that this is not possible but wanted experts feedback here.

SMTP How pro-grammatically set a specific outgoing email importance so that (for example) OutLook would flag it as a "Red" category.
   
 I am using libCURL  and assumed there would be a curl_easy_setopt() function to do it but have not found it yet.

Hey Experts,
I’m a huge fan of your site and have been using you guys for years now and I absolutely love your Experts. Thanks for all the help throughout the years.
I have a dilemma that I hope you all can help me with... I consider myself quite good with Exchange (all versions since 2000) … but I still can’t create my “best environment” I could probably manage because of all  the Pros and Cons… so little advice will be very helpful.
Here is my current environment:
-      Single Hyper-V VM machine with 20 CPU’s and 32Gb RAM, replicating that VM every 15min as well as doing Altaro full backups every day.
-      Single Exchange 2010 with 7 database stores each store on different drive with 400Gb space for each drive (at least 100Gb free on each drive)
-      I’m running multi-tenant environment for about 15 small customers totaling to about 700 mailboxes

I’m in a process of upgrading the above environment and that’s where I need a little bit of an advice. I’m planning to upgrade above environment as follows:
-      New Hyper-V machine, quite powerful again (like above, even better as far as resources) with replication running every 15 min and Altaro full backups at night
-      I’m planning to have Windows Server 2019 Standard operating system on it, install Exchange 2016 in co-existence with above Exchange 2010 environment and then move over my existing 2010 Exchange environment to the new environment. Then remove/demolish the Exchange 2010 and upgrade to Exchange 2019 (in-pace upgrade …

Does anyone out there have experience using Network Solutions as your email server and Trend Micros  Hosted Web Security product? I have brought both Network Solutions and Trend Micro is on this over the past couple of months with no luck. As soon as we adjust the mx and txt records as per Trend Micro's instructions I can no longer receive emails. Every incoming mail is rejected with this message "<myname@mydomain.com>: host mail.mydomain.com[206.179.246.149] said:
    503 you must authenticate first (#5.5.1) (in reply to MAIL FROM command)". As soon as I remove these records emails begin to flow again after about 15 minutes.

Environment

SBS2011 w/ Exchange 2010

We've had an urgent need to create a login for a board member.  As part of this I have created address book policies to restrict what GAL the board member sees when he logs in, and one that excludes the board memeber from the Organisation GAL.

In OWA the GAL's work as expected, the Board member only sees:
  • his entry in the GAL
  • The GM's
  • Mine (Tech Support)

When we log into OWA as an employee the Company GAL created via ABP:
  • All staff appear
  • The GM appears
  • Mine
  • The Board Member does not appear

What is odd is that when I open OLK 2016 the Board Member sees the whole GAL

Any thoughts?

Exchange 2013 CU18 to Office 365 Public Folder Hybrid Migration Batch stuck at "Completed with Errors." After running the "Complete-MigrationBatch", The Primary PF mailbox and 2 of the Secondary PF mailboxes are showing "Complete" however the rest of the PF Mailboxes are staying at "Synced". No i read taht i need to be patient and just let it run, but the logs are showing no activity from what i can tell.
I ran the following and examined the output but no changes are being made:
Get-PublicFolderMailboxMigrationRequest | Get-PublicFolderMailboxMigrationRequestStatistics -IncludeReport
Get-MigrationUser -Batch PublicFolderMigration | Get-MigrationUserStatistics -IncludeReport | fl

Looks like the last Log entry is: "Stage: IncrementalSync. Percent complete: 95."

Does this mean I just have to wait? Or am I missing a step that needs to be run on these mailboxes? I am assuming that the Batch should Not say "Completed..." while most of the Mailboxes are showing as "Synced"

Thoughts?
