Is a specific OST file ANSI or Unicode?

C

Chris Yarnell

I have been researching this for a while now. How can you tell if a specific
..ost file is Unicode or ANSI without trying to actually trying to sync a 3gb
mailbox to it and see it fail or succeed? I have found that you can easily
determine if a PST is Unicode or not by looking at the properties of the file
from outlook. It will say "Personal Folders File" for Unicode and "Personal
Folders File (97-2002)" if it's ANSI. I have found that it's possible to set
group policy to force Unicode if outlook is in Unicode mode by using the
Outlook 2003 administrative template. I have discovered how to determine if
outlook is in Unicode mode (right click on the root of the exchange server in
outlook, select properties, then advanced twice and look at the description
of the mode in the lower part of the box), but I have yet to find a way to
determine if a specific OST file is currently in Unicode or ANSI format. I
am using Exchange 2007 and Outlook 2003.

We are migrating from a non-Exchange server to Exchange. During the
migration, I want to ensure that all OST files are in Unicode by the time we
leave their machine to ensure that they will not have any problems if/when
they reach the 2 gb limit. I have seen many posts like "delete the current
OST file and it will be rebuilt as Unicode", well I want to be guaranteed
that the file that is created actually is a Unicode OST. Does anyone know
how to confirm this? Thanks.
