Hi, I have being using Outlook 2013 for email but i have face for two main issues as below which is quite annoy me sometime. 1. Email stucked at Outbox (even is just a normal email without attahcment). Those emails which were stucked at Outbox will goes missing if i just close the Outlook and re-open the Outlook again. 2. Outlook will hangs/ freeze (showing Not Responding) when half way I just viewing my email in Inbox or I click on Calendar. I have tried to some of the suggestion across other forums such as: - Disable the add-in (example: Social Outlook Connector/ Lync Meeting (which i dont have it to use) and etc.) - Checked on the Program Features and clear all the office plugin - Change the Aero Setting in Windows - Disable Anti Virus (Just guessing)

- Reinstalled the Office 2013 (Outlook 2013)

- recreated the Outlook profile

However after tried, the first two issue still happened and the critical part is the email will goes missing after i reopen the Outlook. More Info: - When the email stuck at Outbox, the Outlook is show "Connected to Exchange" - My company is using Exchange Server 2007 R2 (not sure got any related or not)

Anyone can get help on this?!!! Thanks a lot!!!

The reason I re-posted this issue as the previous as remarked as answered but somehow after that no more ppl reply.. i need more ppl's suggestion here!! 

Thank you

Hi,

Generally for emails stuck in Outbox issue, we need to try basic steps as below:
1. Work offline, move the stuck mail into another folder. Restart Outlook and Work online to send it again.
2. Temporarily uninstall or disable firewall and antivirus software.
3. Test in Outlook safe mode.
4. Create a new profile and re-setup your account.

As you have tried to disable Anti-virus, we also remind you to disable the firewall to test.

Please run MFCMAPI to check if there are emails or corrupted items that are stuck in Outbox, if yes, please delete them.

Here are some articles which use MFCMapi from where you can get some step by step guidance:

We can also perform a clean boot to determine if background programs are interfering with Outlook:

I'm facing the same issues as the Original Post. Two of our Surface tablets are now having issues with mail sticking in the outbox. As the OP stated, certain actions cause Outlook 2013 to freeze / crash. Send / Recieve all will cause a hang and crash. When this happens all email in the outbox are lost. Incoming email is still fine, and as a workaround, I'm able to move the email to the Drafts folder where it instantly syncs to our Exchange 2007 server and can be safely sent from the OWA. Restarting Outlook then corrects the issue temporarily. 

I have uninstalled our AV entirely and will be using MS's built in Firewall and Defender until this can be resolved. The issue persists.

I updated one machine so it is completely up to date, fully patched, Windows 8.1. The issue persists. 

I have recreated the user's Outlook Profile. The issue persists. 

The issue is intermittent, so "testing" Outlook in safe mode isn't an immediate option. I can create a shortcut to launch Outlook in safe mode for the user if needed, but testing time would be needed. 

** I have disabled all Add-In's from the File Menu, Options, Add-Ins window**

I'll work with MFCMapi and post back, I'm unfamiliar with the tool and at first glance, the article doesn't follow a step by step for outbox corruption.

Same issue here.

Windows 8.1 fully updated, Office 2013 fully updated.  

I am frequently having messages go to the outbox, sit there and do nothing.

If I close and restart outlook 2013 the outbox is empty but the message was not sent.

Have tried simliar actions of those above me, no luck.

I am having the same issue.  My version of Outlook is Microsoft Outlook 2013 (15.0.4541.1004) MSO (15.0.4551.1007) 32-bit.  We are using Exchange 2010

The issue is intermittent but has occurred at least twice now.  We also have another user that reported this.  The issues seems to have occurred after the latest patches in Dec or Nov.

Same issue here.  -recreated the OL profile. Using Office 13 (latest updates) and Windows 8.1 

The messages "disappear" from the outbox. Messages show like as if they have been replied to and hang around the outbox until outlook crashes, then re-opening outlook the messages are neither in sent items or the outbox. I have a surface tablet hooked up to my OL and it has not done it so far. Only windows. However I went so far as to remove the Outlook folder from AppData and Outlook still will hang intermittently clicking send-recieve after things are stuck in the outbox.

Many important messages I have replied to have been "lost forever" if I'm not paying attention to save messages out of the outbox before outlook is about to crash. 

I am almost certain this is because of an outlook update.. but I haven't had much luck figuring out what update. After reinstalling office it was about 3 days before the crashes started again.

Hopefully someone on this thread comes out with a real fix.

Same problem just happened to a user here as well.  He had several emails stuck in his outbox I couldn't figure out why they were stuck there so I tried restarting outlook and they disappeared and he lost all of his emails that he'd written.  Hopefully someone finds a fix.

Any Solution to this?  I have the same issue, and cannot replicate with Microsoft as to why!

I have outlook 2013 and word 2013 with excel 2003 and the compatibility for 2007 (For Excel 2003)

All Pc's connecting to Exchange 2013 SP1.

All I know is the sent items are actually in the recovered deleted items folder, but that's all.  I need this fixed since email is the most important communication for us and everyone assumes a sent email with no error is sent.

We spent a ridiculous amount of hours with Microsoft Premier support on this.  The end result = network PSTs.  We previously used Outlook 2007 and have hundreds of network PSTs spread-out across many users.  Many hours of testing concluded that Outlook 2013 behaves differently than Outlook 2007 when it looses network connectivity or there is a network state change (docked to undocked or vice versa).  With Outlook 2007, it would generate an error when the network state change occurred and the PSTs were accessed.  With Outlook 2013, it tries to continue to reconnect in the background and cannot negotiate the network state change (wired to wireless or vice versa).  Eventually Outlook 2013 will hang, but not always right away.  We have see where the user will continue to get mail, but email will start to queue in their Outlook as this condition is occurring.  The end result is always Outlook hangs and the process needs to be killed.  In most cases, Outlook restarts cleanly.  In the worst case, it does not restart cleanly and any email in the Outbox is lost.

Of course Microsoft pointed to their support statement on network PSTs when this was discovered.  We tried to get their to determine what changed between Outlook 2007 and Outlook 2013, to cause this behavioral change it was going to be a futile exercise because they would not had changed anything.  So we gave it up and had to add getting off of network PSTs to our Office 2013 rollout.

For what its worth, we were able to duplicate the same scenario with PSTs stored on external USB hard drives that are frequently connected and disconnected.

We have the same issue with PSTs stored on an USB external HDD. The information on the drive is encrypted and I believe this creates some latency on accessing the data. I hope Microsoft will fix this BUG.

I have a similar problem as the original poster and the subsequent respondents only my messages go to the draft folder rather than getting stuck in outbox.  When I try to reopen the draft email, Outlook stops responding and I need to restart the program.  I have been able to get instruction on the subsequent deletion of the email, but it is frustrating as I can't open the email to see what I said so I need to repeat the message wasting huge amounts of time.  Ironically, I am seeing this happen when responding to a particular person.  I am wondering if the sender of the email or the address could have a problem in which case I will stop sending messages.  Regardless, this shouldn't happen and didn't happen until I upgraded to Office 2013.

I should point out this is a stand alone laptop computer not connected to any server.

Same happened to one of my users with no clue of what the problem is.

We're using Outlook 2013 and Exchange Online, and no networked PSTs.

Behavior is the same already mentioned: user sends mails (without checking if are sent or not, logically it should run well). After working outlook freezes and needs to be rebooted. After starting it up again, no mail in sent, draft or outbox. Checking exchange message trace, messages are not sent.

This occurs randomly.

Thanks for any help.

I just lost hours on this and I don't have a networked *.PST file (I do sometimes open a networked Archive PST file but not my active outlook file).

I am still reeling from the fact that there were around 10 emails in my outbox - many of which I can't recall and one to my boss's boss that took me hours to research, compile and compose.

I'm wondering if Win 8.1 and all this OneDrive stuff is somehow involving my *.PST.

What a bad day.
