Unfortunately, there is no opportunity to delete / re-name 'Contact Tags
' in group of contact using the current version of ONLYOFFICE
We will definitely forward your suggestion to our development team for further consideration.
Please, note, that you can delete contact tags in group only if they are linked together. For example, if you have one company in the CRM
module, with which are linked 100 contacts, if you delete a tag from the company or from one contact of this company, you will see a specific window to delete this tag from all linked contacts. To learn more information about how to use tags within the CRM
module, please, follow this link: http://helpcenter.onlyoffice.com/tipstricks/crm-tags.aspx
If you have any ideas on the improvement of ONLYOFFICE
platform, you are always welcome to share them with us on our feedback page: http://feedback.onlyoffice.com/
