We are running Small Business Server 2011 and use the public folders within Exchange 2010 heavily, saving all emails worth keeping into public folders. The size of the public folder database is around 210GB currently.
We will be migrating away from SBS2011 soon, and are considering both on-premises Exchange and Office 365. Users have noticed that when working remotely, public folders are noticeably less responsive than when in the office. Remote users have a variety of Internet connections, including Fibre To The Premises, and all report the same behaviour. The connection in the office is a 20/20 leased line.
Our questions are as follows:
1. Is Office 365 likely to reduce performance for all users (because is it remote for everyone)?
2. Are new versions of Exchange on-premises likely to improve performance, or leave it unchanged?
We are looking for real-world experience of one or other of the above solutions in order to make an informed decision on which option to choose. Many thanks.
