Hi,

This one has me stumped.. after working with MSX in one form or another since 5.5, I haven't seen anything like it.

Essentially we have one mailbox user on an Exchange 2013 mailbox server. Whenever you send them a meeting request, it shows up in their own mailbox, along with someone else's mailbox. In the info panel it reads:

'Received for USERNAME'

Where username is the actual person you invited to the meeting, and the other mailbox is just that, another mailbox. USERNAME doesn't have any rules to forward to the other mailbox.

Does anyone have any suggestions for why this might happen? It only happens with meetings sent to USERNAME, other email and etc.. works fine. I am also not aware of anyone else having this problem.

Thanks!

Hi,

We're having trouble getting our employees to BCC all distributions lists in our company.
Problem resides in everyone clicking 'Reply to All' to reply which, much sooner than later, always floods everyone's mailbox and creates a lot more traffic than necessary on our Exchange servers.

I tried setting up a rule in ECP using a collector mailbox as follows:

-If the message is sent to a specific DL
-And is received from inside the organisation
-Set audit severity level to 'High'
-and blind carbon copy (bcc) the message to that same specific DL
-and redirect the message to BCC (a mailbox we created)
-stop processing more rules

With these settings, it doesn't seem to work.
Mails keep coming in as being sent by myself instead of from BCC (as I suspect the proper rule should do).
Any ideas?

Hello There,

Could you guys Help me?

We have an external app hosted on a vendor Webserver. They need to send e-mails to our Exchange Environment, authenticating the e-mail.

To allow that, I understand that:

1 - I need to create a receive connector

2 - Scope the Receive connector to the External IP Address of the vendor's website

3 - Configure the Exchange User authentication mode.

Is that correct? I know that some applications need to allow the Anonymoys Authentication checkbox and also allow the relay through the Add-Adpermission cmdlet, but I guess that this is not the case. The application has a secure Method and uses a username and password that we created. Or Am I understanding this incorrectly? All e-mails that users send using another applications that not Outlook, ActiveSync of OWA are automatically classified as "Anonymous" even if they use a Username, Password?
The Application uses the New System.Net.Mail.MailAddress method on Visual Studio.

And, if you guys can answer another quick question that I cannot find the answer, it would be great: IF I have a load balanced solution for my CAS servers and create a receive connector in just One server, will the sender bounce if the connection is balanced to another CAS that does not have the receive connector?

THANKS!

Greetings,

We're trying to roll out TLS 1.2 in our test environment and can't seem to get Exchange to work with the protocol.

We've been using this method to enable TLS 1.2 (and disable the other protocols - TLS1.0, SSL2.0, SSL3.0, PCT1.0): http://www.adminhorror.com/2011/10/enable-tls-11-and-tls-12-on-windows_1853.html

We originally tried using Exchange 2010 on 2008 R2, but then I ran across this article saying that it is not supported: http://support.microsoft.com/kb/2709167/en-us

We've since tried to set it up with Exchange 2013 on Server 2012. Still no luck. The only time Exchange wants to work is when TLS1.0 is enabled.

I suspect that TLS1.1 and TLS 1.2 are also not supported on Exchange 2013, or that I'm changing the wrong registry keys, but I wanted to find confirmation. I've searched extensively and can't find any documentation leading me to believe one way or the other if it's supported.

Any help or insight would be greatly appreciated. Thanks!

Hello,

I'm running an exchange 2013 system and we have an issue that if users sent Encrypted emails they show up on older versions of Outlook and mobile phones as ATT00001 and ATT00002.bin. It doens't matter from what client we sent it. And it is not an issue for Outlook 2013 and newer mobile phones like Vlackberry 10 or iOS8 devices, but on older devices it doesnt display correctley, and in OWA it is un readable (with S/MIME extention installed). When I look at the header it says|:

Content-Type: application/ms-tnef; name="winmail.dat"
Content-Transfer-Encoding: binary

And this is weird as I have TNEF turned off :

I've tryed changing the MIME types and message encoding options but keep getting the same result,

Is there maybe some setting that overrides the exchange conversion, that I'm overlooking?

Hi There,

We have 4 sites (A,B,C & D) ,all connected to site A with an MPLS connection.Exchange server resides on site A and clients from all sites access emails through Outlook.Request your guidance on issues we come across;

  1. Some of the clients keep getting an authentication popup (Even on Site-A).Restarting outlook may solve the issue.

  2. A particular user on Site-B repeatedly complaints about  a non response from outlook and when we try OWA ,It says "Mailbox           Un-available ".But it re-instate to normal after a while .

Request your advice on both matters.

Thanks In Advance,

Hi all,

An interesting one for you out there. We have a law firm as a customer and they would like to delay all emails sent so that there can be a final check before emails leave that confidential material is not going to the wrong person.

Does anyone know if it's possible to configure Exchange 2013 to automatically delay all messages for all users in their outbox. I know it can be done per message but what about globally for all messages.

Alternatively, any other options to achieve what they want?

Thanks,

Richard

Hi All ,

In my current environment we have one exchange forest with exchange 2013 and another exchange forest with exchange 2010.

Lets say a mailbox user from exchange 2013 forest is sending an mail along with attachment of (1.7 MB) to one of the mailbox user in same exchange 2013 forest and also to one of the mailbox user in exchange 2010 forest .

So on such case the size of the delivered message to the both the mailbox users in the different forest varies.We have found that with the help of message tracking logs in both the forest.

 I mean the mailbox user in the same forest (i.e exchange 2013) receives an message with a size around 1.7 MB and the mailbox user in the other exchange forest (i.e exchange 2010) receives an message with the a size around 2.25 MB .

Questions : 

We would like to know that how the size of the delivered message varies between the mailbox users in the different exchange forest ?

Is this is the default mail delivery behavior in exchange between two exchange forest ?

Note : On my end i thought that the message from the exchange 2013 forest to exchange 2010 forest was processed two times by the categorizer (one time in exchange 2013 and one time in exchange 2010) because of that size is varied .But i am not sure on my end .

All of your suggestions are much appreciated .

Thanks & Regards S.Nithyanandham

Hi,

We have an very strange issue with Exchange 2013 (CU8, issue was the same with CU7) and receive connector on CAS. We have 1 CAS server,1 Edge and 2 Mailbox servers. This started to happen when 2010 was uninstalles/removed. Everything worked before 2010 was removed. 

We have a seperate Receive connector for mail relay from scanner/software etc. If we try to send to external addresses (user@external.com) we got this response:

"451 4.7.0 Temporary server error. Please try again later. PRX1"

If we send with internal address (user@internal.com) its works. Anonymous access is configured. The strange thing is that when we test and send a test-message with both internal and external address (user@internal.com; user@external.com), both is delivered OK. 

Used this commands to test:
This command works:
Send-MailMessage -From test@internal.com -To user@external.com,user@internal.com -Subject TestMail -SmtpServer serverip

This command gives errorcode:
Send-MailMessage -From test@internal.com -To user@external.com -Subject TestMail -SmtpServer serverip

Send-MailMessage : Error in processing. The server response was: 4.7.0 Temporary server error. Please try again later.
PRX1

We have created an case with Microsoft, but the response from MS is very bad/nothing.

Anyone that have seen this behavior?

Hi Exchange Server Expert,

Our company is using Exchange 2010. Each of the mailbox has been configured to have default quota of 3GB. When it reaches 3GB quota, the send/receive will be prohibited.

My question is:

1. if there are senders are sending email to specific user whereby his/her mailbox has reach quota, will the sender receive any bounced back message?

2. If he/she clean up their mailbox, will those bounced back email being flushed back to their mailbox or the sender need to re-send again?

3. Will the user know that there are senders that sending email to her but he/she can't receive because he/she has reached quota?

Thanks.

Sometimes despite users accept or decline for meeting invitation mail in Outlook, 

It's reflected on outlook but the mail only wasn't delivered to meeting owner.

any similar issue?

I admit this has been in my "If you don't look at it funny, it will not mess with you" category.  However after having some interesting conversations at Ignite last week I decided to go back and look at this.  

Occasionally I have a user that reports the "IMCEAEX" NDR.  I have always had them delete their address autofill cache and the issue was resolved.  Our mailboxes have X.400 addresses assigned.  They have been there since I took over the environment.  There are no X.500 addresses.

I ran the following to see if there are issues I was not aware of:

Get-TransportServer | Get-MessageTrackinglog -EventID FAIL -Start (Get-Date).AddDays(-7) -ResultSize Unlimited | Where {$_.Recipients -match "^IMCEAEX*"}

This returned a large number of results.

My question is, do I need x.400 addresses?  Should they be x.500?  Would removing the x.400 resolve these NDRs or possibly make it worse?

Hi,

how can we use C++ with gSOAP to fetch email data from outlook mail (in office 365) using exchange web services. Is there need to be authentication API of office 365, and if yes, then does this API support C++ language.

OR gSOAP is enough to read the data of email from exchange server of office 365. and in gSOAP is there need to be authentication, If yes then which one? please help me.

Hi,

I have Exchange Server 2010 Ver 14.0(Build 639.21).

How to reject spam emails and reject non fqdn domain?

I dont have antispam server, I only depend on the Exchange antispam.

Please Help Me..

Thanks.

First, let me state that I have no problem forwarding mail to MOST external contacts by simply setting up a "Mail Contact" via ECP. Further, it appears that 100% of mail from internal addresses goes through properly to all external contacts. Where I run into problems is that for some mail originating at external sites, some users' ISPs reject the forwarded mail as spam. This happens often enough that I suspect I have not set up everything properly.

I don't have a problem forwarding to gmail.com, outlook.com, or other big e-mail systems. The e-mail may end up in the recipient's junk mail, but at least it gets through and users can add us to their Safe lists to prevent this problem. But with several ISPs, the mail is blocked completely. Nothing reaches the contact at all, nor does the sender get a message back with any kind of support information (because these are forwarded messages, even if there were a reply, it wouldn't come to us). Example ISPs that reject forward messages at the SMTP level include EarthLink and FairPoint.

We are not on any DNS blacklists. Whatever the reason for the blocking, we assume (don't know for sure) that they are exceeding some spam score threshold and triggering the block. Supporting this hypothesis: test mail I send from my own gmail or yahoo accounts to their address on our Exchange Server does reach some of the problematic external contacts, but automated mail from other sources (like invites to complete registration for third party tools, like a RingCentral phone account) never reach these users.

These are completely legitimate individual e-mails that are being rejected outright by the external recipients' ISPs.

A few questions on this problem:

1. Everything I see on the Internet says to create a user account and a mail contact, and then forward the user's mail to the mail contact. This has always seemed like a waste of time for me -- I just create a mail contact John Doe in ECP, with an internal address of John.Doe@MyCompany.com, and then set it to forward to John's external SMTP gmail account atjdoe@gmail.com. Am I missing something? Is there any benefit to also creating the user account? If all mail is only going to the person's external mail address, is there any problem with only creating the mail Contact as I have been doing? Could this be related to the spam blocking problem with the forwards?
2. Are there any rDNS or other settings I should make either on the Exchange server, our on-site DNS server, or with our external DNS to make our mail appear more legitimate and less likely to be flagged as spam? Maybe we've failed to follow some best practices on setting everything up, which increases our spam score, explaining both the rejections and the frequent junk mail filing.
3. Any suggestions on how to better research this to find out WHY the messages are being blocked? The ISPs don't respond to questions on this. Their support personnel are unaware and claim they don't block e-mail. But obviously they do.

Thanks for any help or suggestions to troubleshoot and work toward a resolution to this problem,
Colin

Hello all,

An issue i am facing with a brand new exchange 2013 install with CU8 is as follows.

I create an email message and address it to multiple recipients both internal and external, i then send the message.

When i go to Delivery reports and view it, the internal recipients all show delivered. External recipient shows as Pending HOWEVER it was SUCCESSFULLY delivered to the external address.  The report does not seem to update and show that it was delivered though. This has happened on every email sent that contains both internal and external addresses.  If an email is sent with ONLY external addresses in the TO field, then it shows as delivered, this issue only occurs when there are both internal and external addresses.

Here is a screenshot of the report, the external gmail address used in the test was mine, and i don't care if anyone knows it.
