Im trying to create an app that converts an .ost file to .pst. An .ost file is a Microsoft Exchange email file and in order to read an .ost file offline you need it to be converted to .pst.

I know theres tools available for office 2000 for free but this does not work with Office 2003 only ones available need to be paid for......if you need more info on this please see http://www.nucleustechnologies.com/exchange-ost-recovery.html

So this leaves me to ask i know how to convert files but what encryption do i need to lets say decrypt the ost file then pack it back in a pst form so its readable in Office 2003 as a .pst file

Thanks

The .ost and .pst file formats being proprietary to Microsoft, there is no documented way to do this, much less with VSTO (which is the topic of this forum).

Thanks for your reply. If this is proprietary to MS how do other manufacturers work this out Or is this an advanced topic or something

Thanks

Can you tell me which tools are available I'm still working with Outlook 2000. As my PC was infected I had to format it and now I can't read my ost file anymore. I'm desperately seeking for a free tool to convert it to pst. As just a private user it's too expensive for me to buy the software.

Waiting your news, regards Dini

Dini000, read the earlier posts in this topic. AFAIK, there are no free tools for this task.

Thanks for your reply. I had read the earlier posts and I did try the demo version of the repair software. And it works super, but 70 dollar is just too expensive. They offer a file repair service to, which will cost minimum 50 dollar. I look further for a (cheaper)solution. Regards Dini

I think its rediculous that one has to pay to have data within an OST file converted to PST. Its really not rocket science - someone's just trying to make a quick buck! After all - both OST and PST are read by Outlook and you own the data....! Not as if it's some dodgy 3rd party software that you're trying to export from...into PST!

Companies spend thoundsand on Exchange 2003 and Office 2003 (including CALS) and a simple export from OST to PST is not available... Just speaking my mind...as an Exchange engineer, I think certain tools should be available to simplify support. The again, its not as if I would use this utility on a daily basis....





Re: Visual Studio Tools for Office Convert .OST to .PST

valdarama, you should never need such a utility in an Exchange environment, since a user can always export to a PST file (unless that's blocked with GPO) and ost files are not a backup solution. Where it comes up most often is in situations where the user left a company with only an .ost file and now can't get to that data (which, some might argue, the company owns, not the user).

In any case, the subject is very, very off-topic for this forum, which deals with issues related to programming VSTO.

Sue and everyone,

My apologies for using this thread to vent my frustration. Was not my intention to hijack the thread.

Sue - have you actually worked in an exchange environment I am a systems administrator/exchange engineer supporting an organization with one of the largest Exchange 2003 environments in the world, including multiple Cluster environments and literally hundreds of Exchange servers accross the globe. When it comes to process management, these guys are pro.

Yes, there are guidelines which organizations follow, but no process is fool-proof. You are correct with regards to potentially needing such a utility in the case where a user leaves the company. Note that the users data is owned by the company. Under most circumstances, the data can be retrived from tape, however, this may have cost implications, depending on your DR solution..

Lets say the OST file was available for a user who has resigned and his/her user profile has been discarded. The systems administrators or Exchange admins would find such a utility usefull, as it would enable us to provide better service delivery to our clients, instead of opting for the complex solutions, such as having to request a restore or purchasing pricey converter software which will only be used on rare occasions. There would be no security threats either, as Exchange administrators have the necessary rights to open anyones mailbox anyway.

I must admint that it is quite rare to have the need for converting OST to PST....so I guess it is understandible that a free Microsot Converter does not exist. It's a "nice to have".

Once again, my apologies....I googled OST converter...etc, came to this site and thought I'd provide some input.

Hi Sue

I could not find a way to export outlook.ost to a PST file. I would appreciate if you could point me to the right menu options.

prapu, it sounds like you've missed the point of this discussion, two points actually. The first is that this is not the forum for asking usage questions about Outlook. The second is that there is no export explicitly from an .ost file to a .pst file. Instead, you use the File | Import and Export command to export to a .pst file from the Exchange mailbox, which will be cached in a local .ost file for most Outlook 2003/2007 users with Exchange accounts.
