kopano-oof: No username specified.

[afischer]

Hello,
kopano-oof complaining “No username specified.” when executing

kopano-oof -u name -m 1 -t "Out of Office" -n abwesenheit_name.txt

We are running Kopano Core 8.7 on CentOS 7.6.

kopano-admin -l

lists users as expected. We executed a command from history. So in 8.6.9 the command worked. Can anyone confirm this problem?

Best regards,
Achim
