I am having trouble with my Microsoft Outlook 2007 and I am hoping you could shed some light on it.
After my hard disk crashed, I was able to recover my files but when I started using Microsoft Outlook, I noticed that I could not add my mail folder into it.
The file is in .ost format and I keep on getting this error message: “The file you have chosen is not an Outlook data file. You must select a new file of this type file.” I tried adding a file in .pst format and it seems to work just fine.
I tried converting my .ost files to .pst through some software I found online but the websites were asking for money before it saves the recovered mail into .pst format.
I need to know if there’s any way for me to add the .ost files to Microsoft Outlook so I could access my mail.
I hope you can help me. Thank you.
How to add the mail folder in MS outlook?
The .ost files / folder are related to the Exchange Server. This means that your E-mail configuration and E mail connectivity is through an Exchange server.
In order to reconfigure your E-mail account, what you require is NOT to convert the.ost to .pst rather to have a proper connectivity with the Exchange server, where all your mails along with the different folders etc. will be present. The .ost is only used when you are NOT able to connect to the exchange server and want to work in offline mode.
Actually, when you are offline, outlook creates a replica of your mailbox from the exchange server to be used, BUT after synchronization. This means that you have to first be online once with the exchange server.
Now if this is the case that you are trying to collect your mail data in offline mode, and cannot connect to exchange server, than you have to use such a tool, which can convert the .ost files to .pst files. And as per our knowledge all such tools are paid for.
There is a site, which offers a limited amount of such conversion, and you can get the complete instructions as to the usage. Visit: http://www.ostfile.com/
But again the full version is still not FREE.
