At present any new user gets kicked out as soon as they log in, with in a fraction of a second. The session looks like this:

...Brian Schenkenberger A.K.A "VaxMan" discovered that SYSLOGIN.COM was not working correctly. It needs to be re-created.
He fixed that problem and now EKOBLENTZ can log in but cannot send email, here is what happens:
Subj: VAX USERN/PASS
%MAIL-E-OPENOUT, error opening COBK$DATA:[COBK.PERSONAL.EKOBLENTZ]MAIL_0128_SEND
.TMP; as output
-RMS-E-CRE, ACP file create failed
-SYSTEM-F-EXDISKQUOTA, disk quota exceeded
TO FIX - When I created the user I also needed to set up a diskquota for the new user. The following example applies to this system, but hopefully you can apply to your case. The reason I run the "diskquota show" command first is to see what others in the group already have allocated, so I can match with same values. It turns out everyone is getting 1000000 blocks
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> diskquota show [100,*]
SYSMAN> diskquota add [COBK,EKOBLENTZ]/PERMQUOTA=1000000/OVERDRAFT=100
NOTE! 1000000 seems like a lot, not sure if this was done correctly by the original admin.
