Exchage server mail box issue.

Hi All,

One of the users in Exchange Server has a mail box size of 500 MB. I have disabled this user but not deleted and then reduced the size to 20 MB. Suppose, if i want to increase the same user's mail box back to 500 MB then will there be any effect on exchange server database (EDB) file. If so, what are the consequences.

Thanks

Laks
