Delete inactivated accounts (can't reactivate them)

Delete inactivated accounts (can't reactivate them)

Hi,

I started with a free edition and three users.
When I switched to the Standard Edition (actually, it is Old Professional), I only needed one user.

When I had several users, I could activate one, so that he could log in and then delete his account by himself.
Right now, if I activated one user but deleted his account, I would no longer be able to log in.

I would like to delete those inactivated users so that my co-workers could use their e-mail again with Zoho.

Is there any workaround ?

Thanks
Jérémie
