Public folders for Hosted Exchange 2013 and Hosted Exchange 2016 improve folder
administration in the Cloud Office Control Panel. Limited Administrator control panel
users have access to the public folders page.
All Hosted Exchange 2013 and 2016 customers can add public folders to their
Exchange 2013 and 2016 customers are allowed to have up to 25 folders per
domain with 250 MB of storage for each folder.
Exchange 2010 customers continue to have unlimited use of public folders.
A new control panel interface will be released for all customers.
Hosted Exchange customers (2010, 2013, and 2016) can use the improved control
panel public folders page and can perform the following tasks from it:

Rackspace will not automatically decrease their number or storage size. For
these users, an example folder structure might display "33 of 25 folders."
Customers with more than 25 folders cannot add new folders until they are

accept new items until content is removed to get below the quota.
The 25-folder and 250-MB-per-folder limits ensure that each Exchange environment
does not exceed the inherent public folder limits that Microsoft® placed on
Exchange Server 2013 and 2016. Without these limits, Rackspace would jeopardize
the stability of our customers' email and uptime. As Microsoft raises the
limits, we plan to raise ours as well.
