Hi - have a local city administration operation looking to bring email in-house for archival, retention initiatives. Currently email is being done via POP-type accounts using a 3rd party provider.
Have appx 10 internal city employees with whom I'm clear on what Windows and Exchange CAL's will be required for these users.
There are also appx 20 outside related personnel (council, board members, etc) who the city wants to start having a better handle on their city-related email communications. These outside personnel currently have a city-specific email address that they're using, but it's all via a web-based login to the 3rd party's hosting services.
My thoughts were to provide an OWA based connection for these outside users to access their city-related email, and then that's where the licensing question comes in.
In order to provide access under this particular scenario (using OWA - archival/retention requirements) - will these outside individuals require an Exchange CAL to be purchased? Will they also require a Windows CAL to be purchased?
