Try to redirect the mailbox to a .pst file or another mailbox whose display name does not have special characters. Here is how to redirect.

Edit: Look under solution 2 in below technote which explains similar issue.

I think you are going to have to log a formal support case for us to look into this more throughly as it looks like it has not been reported to us against BE 2012.

If you do log a formal support case then please quote "ETRACK 2821172" which seems to be similar and was apparently found by QA enginers working on the next BE version. Quoting this reference will hopefully speed up the handling of your case.

BTW AFAIK the reason we have problems with this is that the [ and ] characters are actually used to show mailbox name and display name in the restore selections - as such you customizing your accounts to use [ and ] then has a conflict.
