We have been using  ZoHo Teambox for just over 6 months and recently  our team members have been getting the following error messages when sending emails, "Sorry you do no have access for this action" or "Entity does not exist". 

Then we noticed that the rules are not being applied. 

Now none of the incoming emails are being tagged or assigned. 

Please advise- Thank you! Suzanne (*not sure if I posting in the right place either!!)
