After set COS for all users as described on previous article, overall the value/features on COS has been rewrite for all users. However, i am still get default value for some users such as quotas. Quotas for some users still using default value (unlimited). if checked via Zimbra Admin | Manage | Account | right click and select edit for account which still using default value on quota, i get the following information


I could click Reset to COS value and automatically value of quota using COS rule. For some users such as 3-5 users, maybe i can do it manually via Zimbra admin. But if a lot of users who have the same value on quotas, manually process is need more time until done. I am decided to using Zimbra Command Line for the shorter time. The following is example command for reset value of quotas to COS rule.

zmprov ma admin@example.com zimbraMailQuota ""

Note : The above command will enforce admin@example.com for using zimbraMailQuota on COS rule. For enforce all users to using COS value, you could make a script as below

vi /srv/reset-to-cos.sh

Fill with the following line


rm /srv/reset-to-cos.zmp
echo "Retrieve zimbra user name..."

USERS=`su - zimbra -c 'zmprov -l gaa | sort'`;

for ACCOUNT in $USERS; do
echo "Enforce COS value for account $ACCOUNT"
echo "ma $ACCOUNT zimbraMailQuota ''" >> /srv/reset-to-cos.zmp

Give execute access and run the above script

chmod +x /srv/reset-to-cos.sh
sh /srv/reset-to-cos.sh

The result of the above script is file with name reset-to-cos.zmp which is located in /srv/ folder. Execute it file with the following command as user Zimbra

su - zimbra
zmprov < /srv/reset-to-cos.zmp

If you want to reset to COS value for another attribute, you could change zimbraMailQuota with other attribute/parameters.

Good luck and hopefully useful 😀
