at the moment we are using imap for our mail accounts and there is only a nas with a local user-db as filerserver. At this place there are 27 User, but this will getting more in a few month.
So we are planning to use an Exchange server online in the cloud. Also everybody should get an Office licence with Outlook, word excel and powerpoint. The nas should stay but the authentication should be realized by using active directory. We want to have virtualized servers.
A server with installed server2012R2 standard and with running hyperV allready exists. So we are able to install 2 virtual servers from this licence.
What do we need to realize an online exchange, that uses our local active directory ? And what office licences are the best and cheapest way for all our people, office 365 or better olp ?
Maybe you experts out there can help me !
