I upgraded our mail server from 8223 to 8251 last night. This morning I find two accounts show mailbox size as 100 MB (should be 20 GB). Also, the password no longer displays in the user panel, and the display name no longer displays in the user listing even though it can still be seen in the user panel. The accounts are now rejecting email because they are over the size limit. I cannot change the mailbox size limit, or reset the password on the accounts. The time zone setting for the affected accounts is also blank and cannot be reset.

I renamed on of the accounts and set up a new one with the correct name, but I am unable to import the old data because I don't know the password and can reset it. So I have now lost two accounts data, 7.8 GB and 1.7 GB respectively. I now have a big problem.

I see the following in my error log, repeated over and over, starting at 9:45 am local time, but it only relates to one of the problem accounts. The other one does not appear in the logs.
