hey, guys gotta question for ya. My archive.pst file in outlook 2000 will not give me access, it says that it is already in use. I have only one session of outlook opened and I have no delegates to my mailbox. Is there a way to find out if any one else is logged on using my username and from what workstation( Windows nt environment)??? or who is using a specific file in this case archive.pst??? My pst's are on a personal drive. Thanks in advance for your help.
