Questions on maximum limit for various parameters related to Email to Case client (NOT on-demand)



I wanted to know the UPPER LIMITS (max. allowed) for the following:

1. The maximum number of concurrent logins allowed for an Email-to-Case enabled user. In other words, are there any licensing limits for a user who is enabled for Email-to-Case and is being used by several instances of Email-to-case client.

2.  The client based version 1.08 of Email-to-case currently has a limitation of 2,500 incoming emails per day. Is this limit for a given instance of Email-to-Case process or is this limit for the underlying Email-to-case user which creates cases in SFDC from the Email-to-Case client process.


Thanks and regards,

There is no limit on the maximum number of concurrent logins.  There is an overall API concurrency limit, I think it's 40, which means that you can have 40 concurrent API processes at once, literally hitting the API at the exact same time (and bear in mind that API transactions usually take less than a second so this limit is rarely hit).  Not certain on the exact number, it might be 50.


There is a limit of 2500 emails that can be imported into your org in one day via any vector (client Email To Case or On Demand Email To Case).  If you require more than that please contact your support rep.
