Replacement EDB file in place, will it clear out the OST files on users systems

I am in the middle of a long long repair on a EDB file in Exchange 2010 SP2. I'm thinking of killing the eseutil /p and letting exchange create a new EDB file.  I will then repair and merge in data from the repaired original EDB file.

What I would like to know is if I put in the clean, empty EDB database store file, when the users connect to that STORE will that in turn clear out their OST file since the STORE at the time will be more or less empty of email.

On one hand, if they are not connected during the repair, the OST file will not clear.  But if they connect to an empty store, it should clear.

On the other hand, my view that the users would be best to remake the OST file anyway after the repair. I would recommend users do that. This should help prevent future errors.

I'd rather they did not repair as I expect it to be a week before I can merge in the repaired EDB file into the live EDB and they will want access to the old emails.

I'd like to know what will for sure happen to the OST file.

If the users connect to an empty store, the OST file will clear out because it is replicating an empty store.

We just had to jump into it. The OSTs did not clear out.
