ost files are used by Outlook 2000 and above to store "off line data" that is these files let u access outlook as if it were still connected to exchange despite the server being un-available. If the files were deleted then the only thing u could do is that try and recover. Apart from that, if you had already integrated his profile when he connected to the new exchange server, his data should be available off the new exchange server. All he needs to do now would be to re-build an ost file using manual synchronization on his system using outlook. hope this helps -----Original Message----- From: Chris Nielsen [mailto:cnielsen@xxxxxxxxxxxxxxx] Sent: Friday, February 28, 2003 2:32 AM To: [ExchangeList] Subject: [exchangelist] RE: OST files http://www.MSExchange.org/ Never heard of OST files. Native Outlook file format is PST files, is this what you meant? These are not saved in any special way, they're just files on the disk. If you did indeed delete his old profile I would suggest you lock down that hard drive ASAP. Get it out of that machine and put in another and run some file recovery utilities on it. Don't let the space get overwritten by new files or the old files are gone for good. --- -----Original Message----- From: Eric Lanyon [mailto:ELanyon@xxxxxxx] Sent: Thursday, February 27, 2003 9:56 AM To: [ExchangeList] Subject: [exchangelist] OST files http://www.MSExchange.org/ I have a user that was part of another domain and recently came into ours. On the old domain, he used OST files. When he came in, I added him to the domain and created a new email profile to the server. Not knowing he had the OST files, I deleted the old profile. Then come to find out he needs the info that was stored in the OST files. He is running Outlook 2000. Any suggestions on how to extract the data? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: cnielsen@xxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: srivask@xxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
