Cannot open your default e-mail folders. The file C:\Users\"USERNAME"\AppData\Local\Microsoft\Outlook\***.ost Is not a outlook data file .(ost)

I am not connecting to an exchange server. I am trying to connect to hotmail and live.com only. This occurred during start up of Outlook 2010 client on windows 7. can anyone help. It is an ost file. Can I edit the file or how do I remove the references
to the ost file?

I appreciate your understanding that this is Exchange forum, for hotmail and live email related issue, we have the correspond forum:
http://www.windowslivehelp.com/forums.aspx?productid=15
Just for your reference, the issue apprears to be the .ost file corrupted. You might need to remove the old one an re-download.
Hope it is helpful.

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...

Outlook 2010 - Cannot open your default e-mail folders. The requesting program is an incompatible version.

Outlook 2002 was installed on one of our Windows Server 2003 Terminal Servers. In the process of upgrading to Office 2010, the Outlook 2002 was replaced by Outlook 2010. Although the other Office 2010 programs seem to work, when we try to use
Outlook 2010 on this Terminal Server we get the following message.
Microsoft Outlook
Cannot open your default e-mail folders. The requesting program is an incompatible version. Contact your system administrator about upgrading your Microsoft Exchange Client.
Does anyone have any ideas on how to correct this?
Thanks,
Tom

Hi Tom,
Outlook 2010 is not supported in Windows Server 2003. For Microsoft Outlook 2010, the following operating systems supports only the 32-bit edition of Office 2010:
Windows XP with Service Pack 3 (SP3)
Windows Server 2003 Service Pack 2 (SP2), MSXML 6.0
Windows Server 2003 R2
For more information about system requirements for Office 2010, please refer to:
http://technet.microsoft.com/en-us/library/ee624351(v=office.14).aspx#section10
Personal suggestion, we can upgrade your Windows server 2003 to higher version for more features.

Outlook 2010: "Cannot open your default e-mail folders..."

When I open Outlook 2010 I receive the message: "Cannot open your default email folders. There is not enough memory to perform the operation.", after which the program closes. This is on a network running SBS 2003, with about 25 users, and I
am the only with this problem. System resources on the exchange server are fine, so I can only imagine a disk usage quota has been exceeded somewhere. Storage limits for my account looked fine. I've tried restarting exchange services, restarting
the server itself, restarting my desktop, etc etc, to no avail.
This specific problem just started yesterday, but I've been having memory issues for months now. Usually, the Send and Receive dialogue will tell me that there are not enough resources on the server, but mail comes and goes just fine. It's never
simply refused to let me open outlook before, like it is now.
I also tried logging in through another computer and using Outlook 2003, which actually let me open the program, but did not sync mail properly.
Also, we use cached exchange mode, so I tried creating a new ost file, but no dice.
Anyone know what the deal might be?

Hi,
I agree with Don’s guess of damaged PST file or MAPI profile. Analyzed your description(sync mail improperly on another computer and using cache mode), this problem might occur when your Outlook messaging profile includes a Microsoft Exchange account
that is configured to Use Cached Exchange Mode, and you have lots of cached public folders. Usually, this problem occurs when you exceed approximately 1,000 public folders, or a gigabyte of space is taken.
To prevent this problem, keep the number of cached public folders to fewer than 1,000. Or, reduce the number of folders until the error or errors stop occurring. If you are experiencing this problem, delete some public folder favorites by using the Outlook
client. In some cases, if you have too many favorites, you may be unable to delete the folders because the error occurs when you click the public folder favorites folder.
To delete the public folder favorites, follow these steps:
1.Download MFCMAPI from http://mfcmapi.codeplex.com.
2.Run MFCMAPI.exe.
3.On the Session menu, click Logon and Display Store Table.
4.If you are prompted for a profile, select your profile name, and then click OK.
5.In the top pane, locate the line that corresponds to your mailbox, and double-click it.
6.In the navigation pane (left-side pane), expand Root - Mailbox, and select the Shortcuts folder.
7.In the results pane (right-side pane), locate the PR_FOLDER_CHILD_COUNT properties. The value contains the number of public folder favorites.
8.In the navigation pane, right-click the Shortcuts folder, and then select Empty Items and Subfolders from Folder.
9.Keep the default options, and then click OK.
Good Luck.

Cannot open you default e-mail folders. The information store could not be opened?

Hi
I have a freshly installed version of windows (windows 7 ultimate x64) and when I put my credentials into Microsoft office via the Hotmail outlook connector (x64) i receive the following error message
Cannot open you default e-mail folders. The information store could not be opened
is there a way around this?

What's the version of Office you are using? Is it a 64bit or 32bit edition?
Check if Outlook is in a compatibility mode:
1> Open My Computer>Local Disk C>Program Files>Microsoft Office>Office XX>Outlook.exe.
(If you are using a 64 bit machine and not using Office 64bit, go to C:\Program Files x86\Microsoft Office>Office XX>Outlook.exe)
2> Right click on Outlook.exe and click on Properties and then click onCompatibility tab. Check if you have any check mark in any of the compatibility mode options. Make sure you also click on the option "change
settings for all users" tab at the bottom of the same screen and look for similar check boxes in the window.
3> If you see any check boxes in the compatibility mode options, uncheck all the boxes and click onApply and OK.
4> Try to open outlook again.
Thanks.

Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The file C:\Users\accountname\AppData\Local\Microsoft\Outlook\emailaddress.ost cannot be opened.

I don't have Exchange or anything like that. I did delete the Windows 8 Mail tile, would that have done anything? I've tried deleting the .ost file and opening again, but it's still coming up. My email is also an old fairly irrelevant server (mweb.co.za).
I've looked on the Outlook 2013 pages here but nothing's working. I can't get outlook to open my gmail address either. Do I need to convert the .ost files or something?

Hi,
First, we can try to open Outlook with /resetnavpane command to check if this problem is caused by corrupted Navigation Pane settings. To do this, press Windows key + R to open the Run command, type
outlook.exe /resetnavpane and press Enter.
If the issue persists, we can try to create a new mail profile in Control Panel and set up your email account in the new profile to check the result. To create a new mail profile, please refer:

I just bought the MacBook Air and tried to transfer my songs from my external hard drive to my mac. now i cannot open iTunes and it said that the file cannot be found or created.

i just bought a macbook air. ive been transfering all my songs from my external harddrive that i had on my previous laptop for itunes. now that i got them transfered. my itunes wont open. it says "the itunes library file cannot be found or created. the default location for this file is in the itunes folder in the music folder." what do i do!?!

How did you move the music? You have to do it in a specific way:
iTunes: How to move your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
do not confuse moving your whole folder and library with moving just media files as in
iTunes for Mac: Moving your iTunes Media folder - http://support.apple.com/kb/HT1449
Quick answer if you let iTunes manage your music: Copy the whole iTunes folder and all its subfolders and files intact to the other drive. Start iTunes with the option key held down and guide it to the new location of the library.

You cannot change your default location of "Creative Cloud Files" for sync from desktop

So, I'm finding that I am restricted from moving the "Creative Cloud Files" container (for syncing to the cloud from my desktop). It is bound to C:Users/Name and will not move.
This is very saddening and seems like an elementary function that should be included.
I do not want to store things on my small SSD C: drive -- thanks.
Am I missing something here?

Hi Mark,
As per Adobe F.A.Q, I would like to state that :http://www.adobe.com/products/creativecloud/faq.html
"Your files remain on your local hard drive. You can also choose to take advantage of the ability to synchronize your local files with your Creative Cloud storage. Even if you choose to sync your files to Creative Cloud, you will always have a local copy of your files."
There are some workarounds, it might work out, you can try it : It is for windows
First, stop the sync and exit the app ( right-click on the Connection icon and click Turn Sync Off, right-click again and choose Exit )
Go to “C:\Users\your user name” folder and locate Creative Cloud Files folder
Move the folder to a different location ( e.g. “D:\Data\Creative Files” ) and make sure that you move complete Creative Cloud Files folder
Run cmd.exe in admin privileges ( type cmd in Start menu, right click on cmd and select Run as administrator )
Type following:
mklink /J “C:\Users\your_user_name\Creative Cloud Folder” “D:\Data\Creative Files”
You should receive message that the junction is created ( refer to this guide if you need more help:Complete Guide to Symbolic Links (symlinks) on Windows or Linux )
Now to test it BEFORE you turn on the Connection app simply copy something to “D:\Data\Creative Files” folder, than go to Creative Cloud Files folder in your users folder and you should see the file you copied
If you are able to see the file, all you have to do is to start the Connection app! Hooray!
This guide should work for Windows 7 and Windows 8.

The same MP3 downloads fine in Internet Explorer.
Thanks.

Do you have any setting for MP3 in Tools > Options > Applications ?
You usually need the QuickTime plugin to play MP3 files on Windows because that is the only plugin that supports that file extension if there is no MIME type specified to play the file with another plugin like Windows Media Player or RealPlayer.

I just had the absolute worst experience ever with some idiot at Adobe's chat support. He took control of my computer and started renaming files to old, without keeping the original name (original.old) like he should have. What he was trying to do did not work. Then he just cut the connection and ran. I am furious. I need help to rename these back to their original name so that Adobe Creative Cloud will open. I have Acrobat, AcroCef, AIR, CameraRaw, Color, InDesign, OOBE, the one he renamed to old and PII. Please help. It should be a file related to Illustrator.

If you still have an issue you may have to see about using the iTunes version (application) included with Snow Leopard 10.6 from the installer or an another one if available online, and see if that will install.
Sometimes you may have uninstall the bits left in your system by the earlier (or later) iTunes installers; as they all leave a trace and these can stop a different version of iTunes from being installed.
Not sure if the following site/link will tell the method...
•Apple - Support - iTunes - install & update:

I clicked to open one of my mail folders and when it opened, it immediately deleted all of the items in it! Why and can I get them back???

In my email app, I clicked to open one of my mail folders. When it opened, it immediately deleted all of the emails inside that folder. This happened with all the others too. How can I stop this and is it possible to get that mail back.

Did you try to open teh fle by double-clicking its icon? If the file was made with an older version of Office, you may get that message. Try opeing PP and, from its "File" menu, see if you can open the ppt. I've foundthat often gets around that message and then yo ucan save the file from the newer version.
If that doesn't work, consider asking in the Microsoft Office: Mac forums here:
Office for Mac forums
PowerPoint is not an Apple product and it seems a lot of people around here avoid Office.
