Public folders availability for Hosted Exchange 2013 and 2016

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.

Summary of limits for Exchange 2013 and 2016 public folders

  • All Hosted Exchange 2013 and 2016 customers can add public folders to their
    email domains.

  • 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.

New control panel public folders page

Hosted Exchange customers (2010, 2013, and 2016) can use the improved control
panel public folders page and can perform the following tasks from it:

  • Create, copy, delete, and mail-enable folders.

  • Change the reply-to address of mail-enabled folders to use an alternate domain
    or domain alias.

  • Use easier and faster navigation and search.

  • See the real-time status of your folders.

Public folder limits for Hosted Exchange 2013 and 2016

Because of the inherent limitations in Exchange Server 2013 and 2016, Rackspace
limits the public folder usage of all domains to maintain the stability of our
hosted servers.

  • You can create up to 25 folders (including subfolders) per email domain.

  • You can store up to 250 MB of content in each folder. You cannot reallocate
    unused storage to other folders.

  • Customers who manage folders through Outlook need a Limited Admin account in
    the control panel. Public folder administration is no longer available in
    Outlook. The primary control panel admin user can create Limited Admin

  • For Exchange 2013 and 2016 customers whose folders exceed the limits,
    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
    below the limit. Folders that are over the 250 MB storage quota will not
    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.

Limits for Hosted Exchange 2010

Exchange 2010 customers have less change. Rackspace will not enforce any
limits on folder and storage amounts. Control panel users will get the new
public folders interface, and they can continue to manage public folders through

Customers who plan to upgrade to Hosted Exchange 2013 and 2016 must meet the
public folder limitations in that version.

The following functionality is not available in the December 2014 release:

  • Moving folders in the control panel. This functionality is available
    after the December 2014 release.

  • Creating alternate email address user names for mail-enabled folders. Existing
    alternate email addresses are retained on our servers and continue to
    receive mail; however, you will not be able to add others.

  • Managing user permissions such as granting read, edit, or delete access.
