Exchange 2007 Random delayed emails

One user of mine has been having sporadic email delays for the last two weeks and I cannot figure out why. We called our email Gateway provider (Dyndns)
and they examined a few of the email headers I've forwarded them and after looking at them they said that it looks like the emails are getting queued up because our server was not accepting the IP it was coming from and it kept getting deferred until it accepts
it from one of the IP's our server "likes". 
To try to resolve that, they recommended that I whitelist their IP range on both the server and in out firewall which was done
last week yet we are still seeing delays on some emails. After speaking with them several times they said there is not much else they can troubleshoot as it seems to be the connection between their server and ours.
Besides for whitelisting, what else can I do to troubleshoot this issue. Is there any logging I can enable on our SBS server?

Hi,
Did you use any antispam or antivirus software on your exchange server?
If so, try to disable them and check the result.
Thanks.

  • Exchange 2010 SP3 - Delayed emails with XLSM attachments...

    Running Exchange 2010 SP3 Rollup 5.  Clients running Windows 7 and Office 2010 Pro Plus SP2.  Have one specific user / client that when sending emails with an XLSM attachment around 5:30AM, the email is delayed getting to the Exchange server and
    is delayed up to 16 hours.  Unfortunately, this is a random occurrence, and not necessarily easy to duplicate.
    The Sent Items on the Outlook client reflect the correct sent time, but the Message Tracking Log on the Exchange server shows the server did not receive the email until approximately 12 to 16 hours later.
    The desktop is a shared system and this issue appears to be isolated to the user's profile, AD account, or Exchange.  I've literally blown away the users local profile and reconfigured it with no resolution.
    Any suggestions are greatly appreciated.

    Hi,
    Please verify whether there is any error/warning/information message left in App log. If yes, please paste the details without sensitive information.
    I suggest re-send a .xlsm attachment for testing to verify whether it delays.
    Thanks

  • Why is exchange 2007 account not displaying all messages in a folder?

    Hi,
    I've got my emails setup under hosted exchange 2007.
    The email account loaded into iphone 3gs AOK, but when I go to folders other than the inbox it doesn't show messages that I know are there. Usually it displays the folder as being empty.
    Refreshing it makes it think for a few seconds and then again come back empty.
    I couldn't see any settings that were to do with age of message. Have I missed something?
    Tia,Far

    There are settings on the age of messages. Also, by default, folders other than Inbox are not synced unless you open them; then you must wait for them to sync. You can go to Settings for the account and select other folders to sync.

  • Cannot send email from Exchange 2007 to Exchange 2013 - Coexistence

    Existing Exchange 2007 SP3 1 MBX, 2 CAS/HT, 2 ET servers.
    I have added an Exchange 2013 server with MBX/CAS role.
    Email will flow from Ex2013 server no problem.  Mail from Ex2007 systems cannot deliver to Ex2013 boxes, it dies in queue with a 4.4.7 expired message after issuing a delay message.
    I can telnet to ports 25, 587,717,465,475, and 2525 from Ex2007 HT role to new Exchange 2013 server.  I can send email from Ex2007 HT role server to new Exchange 2013 server using telnet to port 25.
    A ‘get-mailbox’ from the Ex2007 HT role server returns the server and database properly on the test users on Exchange 2013 server.
    The only strange thing I am seeing is from the Ex2007 systems, a ‘get-exchange server’ command shows the new Ex2013 server as role ‘16439’ which looks to perhaps be normal.
    Why is email not flowing to the new users on Exchange 2013?

    You should have exchange server authentication ticked in Default Receive connector in Exchange2007.
    Exchange 2007 and Exchange 2013 in the same subnet/network. if not please check any spam agent running between the networks. Are you running antispam on Exchange2013 ?

  • Outlook 2013 randomly loses connection to Exchange 2007 server

    Hello everyone,
    I have received complaints from some of our users over the past couple of months about them not receiving mails or about sending mails which do not get delivered. A little bit of investigation into the matter showed me that Outlook 2013 had lost its connection
    to the Exchange server. (Which is Exchange 2007 SP3 running on Windows Server 2008 / SBS2008, in case it matters.)
    Which is bad enough in itself - none of our users running Outlook 2007 and 2010 had that problem - but it also does so in a rather inconspicuous manner, so the users did not notice. Closing and restarting Outlook helped every single time, but the users did
    not notice when this happened, and telling them to just restart Outlook every hour or so does not seem like an overloy practical idea.
    All of the clients encountering the problem are running Outlook 2013 on Windows 8/8.1 Pro. We do not have any clients running older versions of Outlook on Windows 8, so I cannot tell for sure if this problem originates in the OS or if it is an Outlook problem.
    The first couple of times I encountered the problem, it was on laptops, so I suspected some power management issue initially. I made sure Outlook connected to the server via HTTPS, which it already did. Then I did not hear of the problem for about two months,
    but recently, two of our users have run into the problem again, and while these were still Windows 8.1 machines, running, of course, Outlook 2013, they are plain desktop computers, not laptops, and I already toned down their power management settings, so I
    do not think that it has to do with the problem.
    Has anybody encountered a similar problem or even - more importantly - a solution? This problem is really frustrating, because our users are very sensitive to problems with their email, and the fact that this problem only occurs randomly and - all in all
    - rather rarely, makes it very hard to track down.
    Thank you all very, very much for any insights you might be able to share with me!

    Hi,
    Please ensure that Outlook 2013 clients retain their connection with the Exchange server using HTTP:
    Have the Outlook 2013 user check the settings under FILE -> Account Settings -> Account Settings -> E-mail tab -> Select the account and click Change -> More Settings -> Connection tab -> Exchange Proxy Settings -> Make sure both
    "On fast networks, connect using HTTP first, then connect using TCP/IP" and "On slow networks, connect using HTTP first, then connect using TCP/IP" are selected -> OK.

  • Exchange any Lync 2010 - delayed emails

    Hi,
    I have Exchange 2010 configured with Lync 2010 to send email about missed Lync calls.
    A certain user is getting those email with a random delay (can be a few minutes up to few days), the user is getting all those mails in a bulk.
    Mails appear in the inbox in their original time and date (time of the missed call).
    What could be the reason they are not delivered immediately?
    The user is properly configured (as same as other users).
    Regards,

    I recommend you post your question in a Lync forum.

  • Can only access emails through OWA after migration from exchange 2007 to 2013

    can only access emails through OWA after migration from exchange 2007 to 2013, in other words unable to access mails through outlook or from other Applications services.
    needed RCA ... plz help..

    Hi,
    From your description, you can send and receive messages only when you use OWA after migration from Exchange 2007 to Exchange 2013. If I have misunderstood your concern, please let me know.
    In your case, I recommend you create a new test mailbox in your Exchange 2013 and check if you can send and receive messages on Outlook. If yes, it is recommended to create a new profile to solve this issue.

  • Routing email from exchange 2007 to 2010 .

    Although this is an
    hypothetical question but still would be a great help if anyone could answer this :  " How email routing takes place from exchange 2007 user
    to exchange 2010 user. I have exchange 2007 and 2010 ,provided i am using single forest with same domain name in both 2007 & 2010 environment "
    Aditya Mediratta

    Hi,
    Firstly,I'd like to explain, message routing from Exchange 2007 to Exchange 2010 is message delivery between responsed Hub Transport servers:
    When a Hub Transport server queries Active Directory to determine the Mailbox server hosting the destination mailbox, it also retrieves the version of the Mailbox server. If the Mailbox server is an Exchange 2007 server that's in the same site as the Hub Transport
    server, the Hub Transport server will relay the message to an Exchange 2007 Hub Transport server in the same Active Directory site.
    For more information about the emails routing process, you can refer to the following articles:

  • SBS2008: Move email from Exchange 2007 to new server with Exchange 2013

    We have an old server (SBS2008) and plan to buy a new server with (Server 2012). I need to move all the exchange emails, contacts & calendars to the new server. We will no longer use the old server. 
    Is there a document or migration tool that will help me understand how to move this data form the old exchange server to the new one? 
    Old Server:
    SBS2008 running Exchange 2007
    New Server:
    Server 2012
    Exchange 2013
    Any help is appreciated!

    Hi Dave,
    It can be done, and as Larry suggested you will consider two Server 2012 installs in order to achieve an environment that looks like your current SBS roles; Exchange 2013 on an Active Directory controller isn't a good long-term solution (SBS did this for
    you in the past).
    For your size operation, a virtual server host, with a Windows Server 2012 license, and two virtual machines would probably be a suitable design model.  In this manner, you have Server 2012 license that permits 1 +2 licenses (one host for virtualization,
    up to 2 Virtual Machines on same host).
    There's no migration tool. That comes with experience and usually trial and error. You earn the skills in this migration path, and for the average SBS support person you should plan on spending 3x (or more) your efforts estimate in hours planning your migration. 
    You can find a recommended migration path at this link to give you an idea of the steps, but its not exactly point by point going to cover you off for an sbs2008 to server 2012 w/exchange 2013 migration.  But the high points are in here. If it looks
    like something you would be comfortable with then you should research more.
    http://blogs.technet.com/b/infratalks/archive/2012/09/07/transition-from-small-business-server-to-standard-windows-server.aspx
    Specific around integrating Exchange 2013 into an Exchange 2007 environment, guidance for that can be found here:
    http://technet.microsoft.com/en-us/library/jj898582(v=exchg.150).aspx
    If that looks like something beyond your comfort level, then you might consider building a new 2012 server with Exchange 2013 environment out as new, manually export your exchange 2007 mailbox contents (to PST) and then import them into the new mail server,
    and migrate your workstations out of old domain into new domain.  Whether this is more or less work at your workstation count is dependent upon a lot of variables.
    If you have more questions about the process, update the thread and we'll try to assist.
    Hopefully this info answered your original question.

  • Exchange 2007,  Contacts and Calendar OK , Email only folder structure

    Hi, as i was reading many different topics I found that many of them had mixed answers between Exchange 2003, Exchange 2003 and 2007. Because of this mess, i wanted to focus ONLY on *EXCHANGE 2007*. That´s been said...
    I have configured my iPhone with the user/pass/domain/address/SSL-ON, the iPhone connects to exchange and syncronize correctly Contacts and Calendar but not the Email. Email just shows folder structure.
    After this first failed attempt I installed the certificate (Unsigned according to iphone and contains "Root Certificate")... No Improvement
    I contacted my IT department , they said that Activesync was supposedly ON in my user profile and that SSL was mandatory. They also said that they cannot start testing thoroughly because it would disroupt other users. They also argue that many users are using activesync service with no problem what-so-ever. However they incouraged me to keep looking for an answer.
    I couldnt find an apple guide to configuration for Exchange 2007, the enterprise deployment guide is just to vague.

  • Conditional Routing of emails from Exchange 2007

    I have a requirement to be able to control the routing of emails from Exchange 2007 based upon the sender email address.
    For example, an exchange 2007 email system has 2 accepted domains, domain1.com and domain2.com.  The system uses 2 external SMTP gateways used for sending all outbound email (gateway1 & gateway2)
    If [email protected] emails [email protected] I want it to travel via gateway1
    If [email protected] emails [email protected] I want it to travel via gateway2.
    All mailboxes are on a single mailbox server cluster, and there are 2 load balanced Hub Transport servers.
    I have looked into various ways of dealing with this and have had no success.  I looked at transport rules, but I dont believe it is possible to specify the next hop.  I've also looked into setting permissions on the send connectors, but it is not clear exactly what permissions I need to set, or whether it will work.
    The only solution I can see is to forward all outbound emails to a separate SMTP gateway (such as postfix) which supports this kind of functionality.  However I would rather solve the problem using Exchange.
    Any suggestions?

    This is not possible natively in Exchange but you can create your own transport agent and hook it with Exchange to configure conditional routing. You may try posting a query in Development forum to get help from developers on writing a transport agent.

  • PowerShell Exchange 2007 Question To count up the total number of email addresses (view/hidden) per GAL

    Hello All:
    I am very new to Power Shell and need some help:
    I have 224 GAL's on our Exchange System (Ex 2007) where, I need to count the total number of email addresses/display names assigned to each GAL.  I am not sure how to set up a for-next loop in PowerShell.  I am not sure how to set a  input
    file/variable, with the names of each GAL.  (GAL is Global Address List)
    I think it's $GALLIST = 'NameofGal1, NameofGal2, etc thru to NameofGaln' where n is the last GAL in the list.
    So I need to now a command which would get all the gal names (Get-AddressList(?) for all the GAL's in the Exchange System and then pipe them into a function to count the number of email addresses.
    In making a start with the following code and got stuck:
    Get-Mailbox | Where {$_.GlobalAddressList -eq “GAL” -and $_.} | Select-Object Displayname, EmailAddresses, count
    Missing or invalid property reference or expression.
    At line:1 char:71
    + Get-Mailbox | Where {$_.GlobalAddressList -eq "GAL" -and $_.} <<<<  | Select-Object Displayname, EmailAddresses, count
    I think I know how to pipe the results to a csv file - with - Export-Csv  -path c:\filename.csv - NoTypeInformation.
    Please can someone advise.  Please help.
    Thanks in advance
    PS - is there a way to access, read and display variable name and value which stores the number of email addresses/per GAL in exchange 2007 database so you don't have carry out a count exercise.  Because this metadata will be in the Exchange DB? 
    Would this be easier to get?
    Started building conditional statement:
    Get-Mailbox | Where {$_.GlobalAddressList -eq "GAL" AND {{HiddenFromAddressListsEnabled -eq $True} OR {HiddenFromAddressListsEnabled -eq $False}} |
    If {{HiddenFromAddressListsEnabled -eq $True} | Select-Object Displayname, EmailAddresses, count ELSE {HiddenFromAddressListsEnabled -eq $False}} | Select-Object Displayname, EmailAddresses, count
    ENDIF
    Export-Csv -path c:\test.csv -NoTypeInformation
    Will this work?  Checking to see how to do a for-next loop.
    $GAL = Get-GlobalAddressList
    foreach($GAL IN $GAL)
    Get-Mailbox | Where {$_.GlobalAddressList -eq $GAL AND {{HiddenFromAddressListsEnabled -eq $True} OR {HiddenFromAddressListsEnabled -eq $False}} |
    If {{HiddenFromAddressListsEnabled -eq $True} | Select-Object Displayname, EmailAddresses, count AS "Count of Hidden Addresses" ELSE {HiddenFromAddressListsEnabled -eq $False}} | Select-Object Displayname, EmailAddresses, count AS "Count of 
    Visible Addresses" |
    Export-Csv -path c:\test.csv -NoTypeInformation |
    not sure if this works and looks spaghetti -like!

    Hi Everton,
    In addition, If you want to export GlobalAddressList, please refer to the script below:
    $filter = (Get-GlobalAddressList 'Default Global Address List').RecipientFilter
    #filter HiddenFromAddressListsEnabled is ture
    Get-Recipient -RecipientPreviewFilter $filter | Where-Object {$_.HiddenFromAddressListsEnabled -eq $ture} | Select-Object Name,PrimarySmtpAddress
    #filter HiddenFromAddressListsEnabled is false
    Get-Recipient -RecipientPreviewFilter $filter | Where-Object {$_.HiddenFromAddressListsEnabled -eq $false} | Select-Object Name,PrimarySmtpAddress
    Refer to:

    Hi
    As per the information and details provided by you, Exchange server 2007 stop receiving emails, then please follow these steps: -
    If you do have a 60 GB partition on the C: drive, one of the first signs of trouble is when the free space on C: drops below 2GB. Exchange 2007 stops receiving external
    emails. This is caused by a condition known as Back Pressure.
    Please check the following: -
    Check the nslook up for correct MX record.
    Run the exbpa and llok for any recent changes.
    Check for the device in perimeter network which accepts connections on port 25 FW or any other anti spam device).
    Try to run a telnet session from the firwall and then out side and drop email on the server.
    I hope this information will be helpful for you.
    Thanks and regards
