I have Outlook 2007 that is currently working with MS Exchange at a hosted datacenter.  I will lose my Exchange access in a few days but I want to ensure that I still have access to the emails that are currently on my PC.  The files are located locally in an OST file (see attachment).
When I lose my Exchange access I assume I will still be able to access the emails that are located in the OST file.  Should I leave them there or move them to a PST file?
After I lose access to Exchange I will connect my Outlook to a POP email account and would like to have the two instances separate but accessible.
Appreciate all suggestions,
Thanks!

Hi :welcome:

 

AFAIK you need to use a tool to convert from OST to PST, the OST2 free can only convert when you have access to the Exchange server without access to the server only paid products will do it.

Outlook Data Files (.pst) are used for POP3, IMAP, and web-based mail accounts. When you want to create archives or back up your Outlook folders and items on your computer, such as Exchange accounts, you must create and use additional .pst files.

Outlook Data Files (.ost) are used when you have an Exchange account and want to work offline or use or use the default Cached Exchange Mode. This type of data file is also used for accounts that you set up with the Outlook Connector for Outlook.com (formerly Hotmail). Outlook Data Files (.ost) are always copies of items that are saved on a mail server and don’t have to be backed up like Outlook Data Files (.pst).

 

My recommendation is that you save your emails to a pst file.  Easiest way to do this is to use the archive function in outlook.

Hi,BenedekFekete,

 

 

There are several methods to convert OST file to PST file.


First, Microsoft does not provide an official tool to do the conversion. However, if you can access the contents of the OST file in your Outlook, then you can perform the conversion manually, as follows:


1. Start Outlook. Make sure you can access all the contents in the OST file to be converted.
2. Create a new PST file.
3. Go to the OST file, select and copy all the contents to be converted with your mouse.
4. Go back to the new PST file, then paste all the contents into the PST file


That will do the conversion.


You can also perform the conversion by export the contents of the OST file to a PST file by following the instructions at:


http://office.micros...HA102534110.aspx


Second, if you can access the Exchange server containing the account data for the OST file, then you can use Export-Mailbox command to export the data into a PST file, similar to convert your OST file into a PST file. Below is the article about doing that:


http://technet.micro...y/bb266964.aspx

Third, if you cannot access the OST file via Outlook, neither can you access the Exchange Server, then you can refer to Outlook MVPs' website discussing about this issue:


http://www.slipstick...sonal-file-pst/


Forth, there are many third-party OST to PST conversion tools you can try, below is a list of them:

Nearly all these tools provide a free trial so you can try first to see if a tool works before purchase it.


Good luck!

I think  the only way to insure you can get your data is to export it to a pst BEFORE you get cut off. You can try to do yorself. You can read information on the microsoft website. https://support.offi...E2-F331F60E2790  Or you can try to use Recovery Toolbox for Outlook tool. https://osttopst.recoverytoolbox.com/

The concern will be to transition without losing mail during the switch.  If you control when the switchover takes place, then make sure your mail is no longer being sent to the hosted exchange service and arriving successfully at it's new destination (POP mail server as you referenced).  Once your mail is flowing to the pop accounts then you know your hosted exchange is no longer receiving new mail and you can export your mailboxes to pst files.  Don't forget to include your contact, calendar etc. data when you export.  Also, if you have public folders you will need to export those too.  It is ALWAYS best to leave exchange gracefully rather than wait for it to go away.
