Outlook 2010 Sending' reported error (0x8004010F): "Outlook data file cannot be accessed.'

I recently moved my outlook directory to a different drive as my C: drive was getting full.
Everything went smoothly except for now I cannot send emails from any of my addresses with the error "Sending' reported error (0x8004010F): "Outlook data file cannot be accessed.'" that I've associated with outlook. Recently I
uninstalled all of Microsoft Office (student) and reinstalled it on the new drive, still getting the same error. I've tried following the steps at http://support.microsoft.com/kb/2659085/en-us
but when I go into the Control Panel to click on Mail (in this case Mail (32-bit) even though I run a 64-bit OS), the icon in the control panel is a piece of paper (leading me to believe it's broken) and when I click on it, nothing happens. I don't
mean my screen flickers or even thinks about doing anything with the swirly circle cursor... it does absolutely nothing.

Hi Stintedvisions,
Generally,
“0x8004010f: Outlook data file cannot be accessed” error is occurred due to wrong configuration of Outlook profile. And as you said that you have been trying all Microsoft methods to resolve, but it’s still not working, then you should use
the inbuilt utility of Microsoft called scanpst.exe. It can identify the bug and repair Outlook in minutes of times.

What causes Outlook error 0x8004010f "data file cannot be accessed"?

any indexing running on the machine? is .pst in the exclusion list?

Hi all, got an interesting one here. A reoccurring problem for one of my clients on all 8 of their desktops when Outlook 2010 comes up with this error. Normally about one machine a month will do it. I know the solution and can repair it pretty quick these days but the manager is now asking why it keeps happening and I haven't got a clue.We've got 8 fairly recent desktops, Windows 7, all built from brand new good quality hardware. Outlook 2010 on each machine has one IMAP account setup. We've got nothing fancy here, the only group policies used are for mapped drives and printers, everything else is very much standard, no 'addins' or integrations with Outlook.The error states the data file cannot be accessed, the file is there and accessible, ScanPST doesn't find any errors, it has not moved, but for some reason Outlook has created an...

New domain, Roaming Profiles, Outlook 2010 gives error 'Your Outlook data file cannot be configured'.

Hi there,
I have recently setup a new domain, with a new domain controller and new exchange 2013 server.
these are running on a cluster of 2 x hyper-v 2012r2 hosts. All VMs are running server 2012 r2.
although I don't think that has any bearing on my issue.
I have migrated all of my existing user machines to the new domain.
We use roaming profiles.
When a user logs into their PC for the first time, all is ok.
when a user logs into a different machine (they log off of their first machine and then log into a second machine),
they get the following error when opening outlook.
'Your Outlook data file cannot be configured. C:\Users\%username%.domain\AppData\Local\Microsoft\Outlook\[email protected]'
I can manually resolve this on each machine by doing one of the following.
1. Before the user logs in, I log in as an administrator or browse to the pc from another machine create a folder in users called 'whatevertheuserssusernameis' (please note, I actually put in the user's username, ie OKIRWAN)
when the user then logs in, their profile is created in %username%.domain instead of %username%.
I believe this is the route of the problem, as when we added the new machines to the domain, and they logged in for the first time to their 'usual machine', there was already a folder in users with their username, so when we added to the new domain and logged
in for the first time, it created a new folder called %username%.domain, however when the user logs into a pc they never have logged into before, it creates their profile in %username% but their roaming profile is looking for their OST in C:\Users\%username%.domain\AppData\Local\Microsoft\Outlook\[email protected].
2. My second way around this is to go to control panel and mail and remove and recreate the users outlook profile.
As I have 100 users, who move to various different machines, these manual options are not really viable.
I have tried redirecting the OST file to c:\OST via group policy, this did not resolve the issue.
All users are local admins on their machines.
if I open outlook as administrator then it loads ok and creates the OST file in C:\Users\%username%.domain\AppData\Local\Microsoft\Outlook\[email protected].
however if I close outlook and open it again without running as administrator I get the following error.
File access is denied. You do not have the permission required to access the file C:\Users\%username%.domain\AppData\Local\Microsoft\Outlook\[email protected]. (even administrators on that PC have full access to that folder).
All users are running outlook 2010.
Any help would be much appreciated.
Kind Regards
Owen

PST is not an Outlook data file error coming while opening the Outlook

Hi,
Suddenly my outlook is showing the .pst file is not an Outlook data file error while starting. No big changes was made to the system to cause this. I had upgraded the IE version to 9 the same day. Done lots of trouble shooting but still not able fix my pst

Outlook 2010 PST Import issue: ".pst is not an Outlook data file (.pst)"

I recently installed the Office 2010 Beta and am attempting to import my old .PST files from Outlook 2007. However, every time I try it I get the error, ".pst is not an Outlook data file (.pst)". The two data files are large (2+ GB in size each) but have been working fine with Outlook 2007. Steps to repro are:
1. In Outlook 2010, click the File tab.
2. Click Open and then click Open Outlook Data File.
3. Navigate to the .pst file to import and then click Ok.
When I click "open Outlook data file" I get the error "the file Outlook.pst is not an outlook data file (.pst).
I've seen at least one other person post this question on another forum... Any help you can provide would be fantastic as I have a lot of history (obviously ;-) tied up those files.
Thanks!

Hi TylerThrasher,
I'm having the same problem, you described above about my pst file "not an outlook personal

Tried all the solutions metionned in this forum but no way unfortunately.
The last thing that I didn't try yet is this recovery tool "Advanced
Outlook Repair 3.4"
which I'm not able to find on internet at all !!!
Really
I need your help as this pst file, will save my life... I got fired by my company for a no sens problem. Now I will start a justice process and all my evidences are inside my emails which are blocked inside this file.
Really, will appreciate your help if you can as you already solved your problem.
Thanks you in advance

Error message 'The Outlook data file (.pst) failed to load for this session.' when adding PST in Outlook addin

Hi All,
I have an Outlook (2003-2013) addin developed using C# (NOT VSTO).
A new client (using the desktop client for Outlook 365) has got a COMException error message stating 'The Outlook data file (.pst) failed to load for this session.' at the code line where I add the PST store (using Microsoft.Office.Interop.Outlook.NameSpaceClass.AddStoreEx).
I have never come across this error message before and there is barely any mention of this message on any forums. The only question I could find regarding this has been asked mid 2014 and hasn't been answered.
I'm fairly sure this is not related to either DisablePST or PSTDisableGrow registry key settings as I check fore their existance and notify the user separately.
Could anyone help me out on how to resolve this? I do not know where to begin even.
Thanks!!
Cheers!

Hi Eugene,
Thanks for the reply.
I pass the location that the PST is to be created (as a string), and the OlStoreType.olStoreUnicode constant.
The client is using a network location to store the PST file (even though we advised them not to) - leading to many corrupt PST files (that they are apparently happy to live with), but this is the first time we came across this message.
I would assume the problem is with that file, as no other clients are having any issue like this.
Have you come across this error message? Do you know what sort of scenario could be responsible for it?
Or would I have to file it under "random problems generated by network PSTs"? :P
Cheers!

Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost)

Fresh installation of Exchange Server 2013 on Windows Server 2012.
Our first test account cannot access their email via Outlook but can access fine through OWA. The following message appears - "Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize
your folders with your Outlook data file (.ost)" is displayed.
If I turn off cached Exchange mode, setting the email account to not
cache does not resolve the issue and i get a new error message - "Cannot open your default e-mail folders. The file (path\profile name).ost is not an Outlook data file (.ost). Very odd since it creates its own .ost file when you run it for the first
time.
I cleared the appdata local Outlook folder and I tested on a new laptop that has never connected to Outlook, same error message on any system.
Microsoft Exchange RPC Client Access service is running.
No warning, error or critical messages in the eventlog, it's like the healthiest server alive.
Any help would be greatly appreciated. I haven't encountered this issue with previous versions of Exchange.

So it looks like a lot of people are having this issue and seeing how Exchange 2013 is still new (relatively to the world) there isn't much data around to answer this. I've spend ALOT of time trying to figure this out.
Here is the answer. :) - No I don't know all but I'm going to try to give you the most reasonable answer to this issue, in a most logical way.
First thing I did when I was troubleshooting this issue is that I ignored Martina Miskovic's suggestion for Step4 http://technet.microsoft.com/library/jj218640(EXCHG.150)because it didn't make sense to me because I was trying to connect
Outlook not outside the LAN but actually inside. However, Martina's suggestion does fix the issue if it's applied in the correct context.
This is where the plot thickens (it's stew). She failed to mention that things like SSL (which I configure practically useless - anyone who ever worked in a business environment where the owner pretty much trusts anyone in the company, otherwise they don't
work there - very good business practice in my eyes btw, can confirm that...) are some sort of fetish with Microsoft lately. Exchange 2013 was no exception.
In exchange 2003, exchange 2007 and exchange 2010 - you could install it and then go to outlook and set it up. And when outlook manual Microsoft Exchange profile would ask you for server name, you would give it and give the name of the person who you setting
up - as long as machine is on the domain, not much more is needed. IT JUST WORKS! :) What a concept, if the person already on premises of the business - GIVE HIM ACCESS. I guess that was too logical for Microsoft. Now if you're off premises you can use things
like OutlookAnywhere - which I might add had their place under that scenario.
In Exchange 2013, the world changed. Ofcourse Microsoft doesn't feel like telling it in a plain english to people - I'm sure there is an article somewhere but I didn't find it. Exchange 2013 does not support direct configuration of Outlook like all of it's
previous versions. Did you jaw drop? Mine did when I realized it. So now when you are asked for your server name in manual outlook set up and you give it Exchange2013.yourdomain.local - it says cannot connect to it. This happens because ALL - INTERNAL AND
EXTERNAL connection are now handled via OutlookAnywhere. You can't even disable that feature and have it function the reasonable way.
So now the question still remains - how do you configure outlook. Well under server properties there is this nice section called Outlook anywhere. You have a chance to configure it's External and Internal address. This is another thing that should be logical
but it didn't work that way for me. When I configured the external address different from the internal - it didn't work. So I strongly suggest you get it working with the same internal address first and then ponder how you want to make it work for the outside
users.
Now that you have this set up you have to go to virtual directories and configure the external and internal address there - this is actually what the Step 4 that Martina was refering to has you do.
Both external and internal address are now the same and you think you can configure your outlook manually - think again. One of the most lovely features of Outlook Anywhere, and the reason why I had never used it in the past is that it requires a TRUSTED
certificate.
See so it's not that exchange 2013 requires a trusted certificate - it's that exchange 2013 lacks the feature that was there since Windows 2000 and Exchange 5.5.
So it's time for you to install an Active Direction Certificate Authority. Refer to this wonderful article for exact steps - http://careexchange.in/how-to-install-certificate-authority-on-windows-server-2012/
Now even after you do that - it won't work because you have to add the base private key certificate, which you can download now from your internal certsrv site, to Default Domain Policy (AND yes some people claim NEVER mess with the Default Domain Policy,
always make an addition one... it's up to you - I don't see direct harm if you know what you want to accomplish) see this: http://technet.microsoft.com/en-us/library/cc738131%28v=ws.10%29.aspx if you want to know exact steps.
This is the moment of ZEN! :) Do you feel the excitement? After all it is your first time. Before we get too excited lets first request and then install the certificate to actual Exchange via the gui and assign it to all the services you can (IIS, SMTP and
there is a 3rd - I forgot, but you get the idea).
Now go to your client machine where you have the outlook open, browse to your exchange server via https://exchang2013/ in IE and if you don't get any certificate errors - it's good. If you do run on hte client and the server: gpupdate /force This will refresh
the policy. Don't try to manually install the certificate from Exchange's website on the client. If you wanna do something manually to it to the base certificate from the private key but if you added it to the domain policy you shouldn't have to do it.
Basically the idea is to make sure you have CA and that CA allows you to browse to exchange and you get no cert error and you can look at the cert and see that's from a domain CA.
NOW, you can configure your outlook. EASY grasshoppa - not the manual way. WHY? Cause the automatic way will now work. :) Let it discover that exachange and populate it all - and tell you I'm happy! :)
Open Outlook - BOOM! It works... Was it as good for you as it was for me?
You may ask, why can't I just configure it by manual - you CAN. It's just a nightmare. Go ahead and open the settings of the account that got auto configed... How do you like that server name? It should read something like [email protected]
and if you go to advanced and then connection tab - you'll see Outlook Anywhere is checked as well. Look at the settings - there is the name of the server, FQDN I might add. It's there in 2 places and one has that Mtdd-something:Exchange2013.yourdomain.local.
So what is that GUID in the server name and where does it come from. It's the identity of the user's mailbox so for every user that setting will be different but you can figure it out via the console on the Exchange server itself - if you wish.
Also a note, if your SSL certs have any trouble - it will just act like outlook can't connect to the exchange server even though it just declines the connection cause the cert/cert authority is not trusted.
So in short Outlook Anywhere is EVERYWHERE! And it has barely any gui or config and you just supposed to magically know that kind of generic error messages mean what... Server names are now GUIDs of the [email protected] - THAT MAKES PERFECT
SENSE MICROSOFT! ...and you have to manage certs... and the only place where you gonna find the name of the server is inside the d*** Outlook Anywhere settings in the config tab, un it's own config button - CAN WE PUT THE CONFIG ANY FURTHER!
Frustrating beyond reason - that should be Exchange's new slogan...
Hope this will help people in the future and won't get delete because it's bad PR for Microsoft.
PS
ALSO if you want to pick a fight with me about how SSL is more secure... I don't wanna hear it - go somewhere else...

Configure Outlook Data File

One of our users received a message after opening Outlook about archiving their email. They clicked on Yes or OK and now when they launch outlook, they get the message "This data file has not been configured. Select an existing file to configure,
or type the name of a new file to create." It then prompts to find the .pst file, which brings up the archive.pst file. If I click Cancel, it displays the message "Properties for
this data file must be defined prior to use". It appears they can still send and receive email but I'm not sure what the errors are about. This is Outlook 2013. Thanks.

Hi Panther ,
First go and check the default Outlook PST file by following the given path:
drive:\Users\user\AppData\Local\Microsoft\Outlook
If outlook.pst exist there, then select it as default from the Outlook settings. On the other hand, if you don’t find any outlook.pst apart from archived PST file then go and recreate the new Outlook data file and save it as default.

Cannot start Outlook 2013: "name cannot be resolved" / "connection to Microsoft Exchange is unavailable" / "___.ost is not an Outlook data file (.ost)"

My work e-mail has a double-login system, where my credentials for work access are one username and my e-mail is an alias of that first username, so they differ from one another. I suspect that's why I've been having the hardest time with Outlook 2013. I
was able to add my account just fine once but changed my mind about using Outlook and removed the account. Now I can't get back into Outlook for the life of me. The error messages that show up are:
1. It asks me to verify server and Mailbox. I've tried it with both usernames (the official work username and the e-mail alias) as my Mailbox info, followed by the email domain (even tried it without the domain) and it still won't verify when I click "Check
Name".
2. This message comes up: The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
3. Then once I click "OK" another pop-up says: Cannot start Microsoft Outlook. The file C:\Users\FirstLastname\AppData\Local\Microsoft\Outlook\FirstLastname.ost is not an Outlook data file (.ost).

Errant Outlook Data File

I recently acquired a new computer and wanted to load my Outlook contact list onto my new computer. I followed online instructions but when I came to identifying the file into which the pst data should be copied, that option did not exist. I tried repeatedly and (although I know not how) finally succeeded. Now, however, whenever I open Outlook, I get a pop-up that reads: "The path specified for the file D:\Outlook\backup.pst is not valid." I click "OK" but that brings up a Windows Explorer labeled "Create/Open Outlook Data File" that is open to my "Documents." Windows 2013 only shows "This PC" and does not provide access to system files. How do I get rid of these pop-ups?

Of course! My mistake. The Adobe Communities have been so helpful, I just went there first. Thanks, SRiegel, for pointing this out. Sorry for cluttering the Community space.

"Outlook Data File" vs. My email address - Why both?

When I go to the Outlook Mail tab and select Folders View, I see two groups of items:
- Outlook Data File
- [email protected]
Both have an Inbox, Sent Items, Deleted Items, Junk Email and Search Folders entry with the Outlook Data File also having Calendar, Contacts, etc.
My question is Why both? The "mail" entries in the Outlook Data File don't contain the entries in the other, and I don't see any way to set the Outlook Data File entries to have my settings.

OK - I figured it out.
When I installed Outlook I let it set up my email account for me and the account wound up as an IMAP account instead of a POP3 account. When I deleted the email setup and then created the POP3 account manually it let me choose "Use existing Outlook data file and now everything is back to normal, i.e., There is only "Outlook" and a single set of maibox entries.
