Hi,
Entourage expects the Microsoft User Data folder to be in your Documents
folder. For OS X users, that's the Documents folder in your User's folder.
When Entourage opens in a new blank Identity, it's usually User error.
Most likely you have accidentally moved your data. Hopefully, you have not
deleted the file. If you have deleted the trash, it's gone. Sorry!
Select Switch Identity (under Entourage in the Menu bar) and see if your old
identity is still listed.
To find your old database, search for "Microsoft User Data" (without the
quotes). You can also search on "Office 2008 Identities" (replace 2008 with
either 2004 or X if you are using an older version)
If you have not used a new identity in Entourage, then copy the entire
Microsoft User Data folder to the correct location.
Fix if you have more than one Microsoft User Data Folder...
Move the entire identity folder you want to use to the Office Identities
folder that Entourage is recognizing. Your identity is named "Main" by
default. Be sure to rename one so you do not overwrite. Your identity folder
can contain more than one identity. Switch Identities to view your old mail.
If you have not used the new identity, delete it. If you have used it and
want to combine the new mail with your original database, drag each folder
to the desktop from one identity. This creates an MBOX file. Switch
identities. Drag the MBOX files into the folder window of Entourage.
You can delete the old folder after you are satisfied with the transfer.
Sometimes updating software (including the OS) can cause problems where
files go missing. See this link for help finding 'lost' files.
