Outlook/Exchange Won't Deliver Duplicate Messages

For testing purposes, I often send multiple automated messages to myself that are identical and it seems that Outlook/Exchange is being "smart" by not delivering subsequent messages that are the same.
Does anyone know is this is the case? If so, can I turn this functionality off?

Hi David,
Great information from Andy.
It still working in Exchange 2013.
More details in the following article:

Please notice the "Message resubmission from Shadow Safety Net" session.
Thanks

Exchange won't get mail messages on iOS

Hi:
Since about 24 hours after my update to 7.1.2, my iPhone (4S running 7.1.2) and my iPad (2 running 7.1.2) will no longer get messages on my Exchange account (Google Apps).
Other apps get my mail fine (like Gmail's own app), and my Mac IMAP client (Apple Mail.app) all work fine, as does web access.
Also, Calendar and Contacts sync fine over the Exchange/Gapps connection. It's just mail that won't work.
I've tried using a completely different Gapps account and also deleting the Exchange account from my iOS devices and reestablishing it. The former worked fine (meaning it's not Google) and the latter did not work at all.
If anyone has any ideas, suggestions or recommendations, I would very much appreciate it!
Thanks.

No, it shows absolutely nothing in the "Inbox" area, even when I had my husband send a brand spankin' new message, that I hadn't clicked on or checked in the browser of the iMac Mail client. I think it's pretty weird, too, but I haven't found anything that will help, other than just checking in the "All Messages" area of the account.

Outlook 2010 won't update new messages unless you update folder

Hi,
Outlook 2010 sp1 with Exchange 2010 latest sp.
Scenario:
Some users are not receiving emails unless they click on update Folder. Once they do emails come in.
Troubleshooting:
No virus scanning outlook folder.
Delete the profile with OST and re-created it.
Send immediately when connected is enabled.
Cache Exchanged mode is enabled (Must be ...there are 15000 users with mailboxes here).
(If Cache mode is disabled everything works fine) This is not an option for us.
Download shared folders whether it is enabled or disabled still the same problem.
Help please,
Alexis

I would suggest your to start Outlook with /cleanips switch and check behavior,
Just click Start, click Run, type
outlook/cleanips, and then click OK. Microsoft KB article:

How can I Delete a MobileMe Email Account and Kill Duplicate Messages?

When I select "All Inboxes" on my iPhone 4s, I see duplicates of each and every message I receive. Furthermore, the duplicate can't be deleted and I get an error message informing so! I suspect this phenomenon is occurring because I have both an iCloud and a MobileMe account. I want to cancel the MobileMe one.
Here's the deal:
My iPhone 4s lists three email accounts, including a "MobileMe" one that I want to delete because I believe it is delivering duplicate messages. However, I can't seem to figure out how to delete the MobileMe's email account or, for that matter, MobileMe itself. Apple support screens refer to cancelling a MobileMe account but are not clear on how to actually do it.
1. On the iPhone 4s, I click on the "Mail" icon at the bottom of the screen
2. On a screen under the heading "Mailboxes," under "Inboxes," there are two that read exactly the same (I think one is iCloud and the other MobileMe).
3. On the same screen, under "Accounts," I see an iCloud account logo, a Bellsouth/Yahoo account logo and a MobileMe account logo.
4. I want to keep the iCloud and Bellsouth/Yahoo accounts but delete the MobileMe one but I can find no way on this screen or any other iPhone 4s screen to do so. Nor do I see any path to do so in iTunes. And the MobileMe account doesn't even show up in the Apple email app on the laptop to which I sync my iPhone.
If I go to www.me.com and log into my MobileMe account, there is no apparent way to disable, delete or otherwise cancel it. Why?
I am convinced that the simultaneous presence of both iCloud and MobileMe accounts is responsible for the double email messages when I select to view "All inboxes" on my iPhone. (A workaround is to simply select just one of the accounts, say, the iCloud one. Then I see only one copy of each message. That's OK but surely there is some way to kill off this redundant MobileMe account AND the duplicate messages, yes???

First, thanks for the reply. And, I believe you are exactly right that the names are the same. However, when I go (on my iPhone) as you suggest to "Settings," "Mail, Contacts, Calendars," only two accounts are showing; my Mac account and my Bellsouth one. If I select either, I get an option to delete but the duplicate "MobileMe" account does not appear. It only shows up, as described above, if I:
1. On the iPhone 4s, I click on the "Mail" icon at the bottom of the screen
2. On a screen under the heading "Mailboxes," under "Inboxes," there are two that read exactly the same (I think one is iCloud and the other MobileMe).
3. On the same screen, under "Accounts," I see an iCloud account logo, a Bellsouth/Yahoo account logo and a MobileMe account logo.
It's nutso, I admit, but true. Any other suggestions would be most welcome.

Mail 4.1, Exchange, and Duplicate messages in inbox

Using Snow Leopard and Mail 4.1 to access an exchange account and a gmail account. The problem ONLY occurs in the Exchange account. My messages are all duplicating. Only in Mail are they duplicating. I've checked Outlook Web Access and Outlook on my windows machine - no duplicates there. Didn't start out this way, and the problem came once before, stopped, and now it has returned. If I delete one copy of the message, both messages get deleted. Is there someway to rebuild the mail inbox? or resync?
Also, tried creating a new folder on the exchange server, copying all messages from inbox to the new folder, then moving back. In the temp/new folder, the messages were single. After copying back to Inbox - they doubled again. And again, only in Mail. The msgs remain single in Outlook, OWA, iPhone, Blackberry.
UPDATE: I highlighted the exchange mailbox and went to MAILBOX > REBUILD. Erased everything but only in Mail. The messages are still on the Exchange server and can be seen by OWA, Outlook, iphone and blackberry. New messages are going to the Mail Exchange inbox but old messages are gone. Any way to get them back?

Thanks V.K.! So there is no chance for me to re upload all the messages from my mac to my yahoo inbox.
nope.
May I ask yahoo to that?
you can ask but they won't say anything different.
I could never have known that the default setting on mac's mail would be "remove copy from server after retrieving a message".
now, that's a valid point. this is not exactly advertised and mail setup assistant does not tell you anything about it. you can voice your concern to apple about this issue here
http://www.apple.com/feedback/macosx.html
I wish apple had some kind of a solution for this.
there isn't anything you can do now. it's not up to apple at this point. you just can't upload messages to a POP email server. it does not matter what email client or what operating system you are using.
Thanks again

Outlook 2013 won't start with Exchange 2003 on the network

Hello All,
I have outlined my problem below, If someone could please help me that would be great!
Environment
==========
SBS 2003 Server Running AD and Exchange 2003
Clients are Windows 7 with Office 2013 and Outlook 2007 (to connect to existing 2003 Server)
Issue
=====
I am in the process of Migrating off of SBS 2003 to Office 365. The situation is that my customer needs to keep the SBS 2003 server until end of life where they will at that time determine a upgrade path. They however do not want to use Exchange
anymore. I have migrated their mailboxes successfully to Office 365.
The problem that I am running into is with Outlook 2013. Because Exchange 2003 server still exists in the network I am unable to launch Outlook 2013. I get a Message
"The Resource that you are trying to use is located on an unsupported version of Microsoft Exchange Contact your e-mail administrator for assistance"
I have tried to create a new Outlook profile. However since the exchange server exists still it auto discovers the server for the account.
Questions
========
1. What is the best workaround for this situation? My customer still needs to keep their SBS sever for their domain and plans on retiring the server before Server 2003 End of Life this coming server. (Upgrade is not an option, nor is getting
rid of the Domain, they are a small company).
2. If I disabled the Exchange services on the server would this work? Would outlook 2013 not detect Exchange
2003 on the network?
Basically I need to force Outlook 2013 to look at Office 365.
3. Configuring Outlook 2013 to manually connect to Office 365? The problem here is that how do I locate the server name for the manually connection? I have found some blogs that say to use Remote Connectivity Analyzer https://testconnectivity.microsoft.com/
but I cant seem to get that to work.
Any ideas?
Thanks!

Hi,
Please refer to the following article to check your migration steps from Exchange 2003 to Office 365:
http://blogs.technet.com/b/canitpro/archive/2013/05/31/step-by-step-migration-of-exchange-2003-server-to-office-365.aspx
If all mailboxes are moved to Office 365, Outlook 2013 would use Autodiscover service to connect to your Office 365. Please make sure your Autodiscover service is configured correctly in Office 365. Also
verify that all the DNS records and Public Folder are updated and pointed towards Office 365 services. If there is any question about migration to Office 365,
we can ask a question in Exchange Online forum for more suggestion:

Queue freezing won't deliver messages to mailboxes

Every now and again my queue seems to build up and won't deliver until I stop and start mail services then flush the queue.
Here is my log, It seems to start filling up right after it refreshed the postfix mail system. I then continually get the message that it was skipped, and will still be delivered. But the messages are not being delivered and people sending messages are getting bounce messages. I've pasted the bounce message below the log.

I'm thinking that this could happen soon after I send out a mass email(50-300 users at once) to one of my postfix email groups. It isn't consistent, because it could happen a few minutes after I send one of those mass mailings, but then it doesn't do it all sometimes either.....
Logs aren't giving me anything other than it will say for the first message that won't deliver (queue active) like seen below. This is everything in the log from a message that would deliver to a message that wouldn't.

Won't Deliver messages through iMessage

Just recently, the messaging function on my 4th generation iPod Touch began to stop working on occasion. I would be in the middle of a messaging conversation and all of a sudden, my message would not deliver. The message will Send all the way, but the notification that it has been "Delivered" will not drop down to my latest message. The only thing that works is if the other person starts to type, my messages will be forced through. The funny thing is that the messaging will be going fine, and then without moving around or disconnecting from wifi or changing settings or anything like that, my messages just won't Deliver. I have had my iTouch for 8 months now and this problem has never lasted more than an hour or two; not it has been going on for 3 days. I only message one person and neither of us have had this problem before, we didnt recently update our iPods. messaging back and forth has been fine for the last 5 since she got her iPhone 4 but now we cannot figure out what to do.
I have done the usual troubleshoot solutions. I have changed my wifi, turned my iTouch off and back on, changed the DNS settings, turned iMessaging off and on, I never get the little ! Not Delivered sign. All the messaging will be fine for 10 minutes and then spotty for hours and then fine for another 15 minutes. Is there anything else I can do?

Does this happen no matter what Wi-Fi network you are connected to? If you aren't sure, I would test this out on other available Wi-Fi network to see if the problem can be isolated to a particular network or if it's just an issue with the iPod Touch itself.
I noticed a similar thing on my iPhone 4 at time, but the messages still go through even though the screen hasn't given me the delivered message.

Exchange 2013 - Duplicate Message Detection

Hi,
I am trying to resend an email from my spam firewall but it is not reaching the user. The duplication detection on the server is not allowing me to resend. If I go back older than a month I was able to successfully resend from the spam firewall.
How do I temporally disable the duplicate message detection on Exchange 2013 server?
I found this from someone else for 2013 but I did not have this path in my registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server_Name>\Public-<GUID>
Thank you

Hi,
After some search, I think we can adjust the expiration time of duplicate message detection. And the minimum value is 1 hour, so we don't need to wait several days.
The registry setting is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\<Private/Public-Guid>\Track Duplicates
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\<Private/Public-Guid>\Background Cleanup

My iPad won't sync calendar with Outlook Exchange but my iPhone will

This is not the Outlook Exchange calendar cancellation problem reported elsewhere on this forum. Our organization has had this problem, but what I describe seems to be different.
I am running an iPhone 4S and an iPad 3, both on iOS 6.0.1. Our organization runs Outlook Exchange 2007.
My iphone syncs perfectly with Outlook Exchange. However, my iPad does not sync properly. On the iPad, only a few appointments show up. If I try to refresh the sync, the few appointments on the iPad disappear while I am watching.
Outlook Calendar on my office desktop on our network seems to work well.
Any suggestions? I have tried rebooting but that hasn't helped.

Have you tried deleting the Exchange account, and adding it again fresh? I had similar problems and this fixed it for me.
