Architecture
Why?
Public folders in O365
High availability, data redundancy, and low cost storage thru DAGs
Multi-master replication simplified and replaced by single-master replication of folder hierarchy
What changed?
No change to end user experience
Public Folder databases replaced by mailboxes
Public folder mailboxes are stored in regular mailbox databases
Each public folder mailbox includes the complete public folder hierarchy
Single writable copy of the hierarchy
Modern Public Folders Architecture
Architecture• Public folders are based on the
mailbox architecture• Hierarchy is stored in all public
folder mailboxes• Content can be broken up and
placed across multiple mailboxes• Similar administrative features• Public Folder permission
management in RBAC

1. Client connects to a PF mailbox
2. Client creates Folder2
3. Create request is proxied via the primary PF mailbox
4. PF hierarchy is updated on all PF mailboxes • Within 15 mins
where users are connected
• Within 24 hours where no users are connected

Content storage Public Folder database Public Folder mailbox
Public Folder content replication Can be replicated between databases
No replication
High availability PF replication DAG
PF Hierarchy storage One per PF database, multi-master
Per PF mailbox, one master only
PF Hierarchy synchronization Based on e-mail Direct mailbox sync

ions
Clients- Outlook 2010, 2007, Office 365 Pro Plus (Outlook 2013)
- OWA 2013 (mail & post type folders)
Exchange Server- E2013 users can access E2013 / E2010 / E2007 Public Folders- E2007/E2010 users cannot access E2013 Public Folders, so
migrate Public Folder users before Public Folder data
Migration support- Cutover migration from E2010 and E2007
- Same forest and cross-premise
Deploying modern public folders Create a mailbox in a DAG• New-Mailbox -PublicFolder
Users create folders and messages• Users grow• Create more mailboxes! (New-
Mailbox -PublicFolder)• Hierarchy is copied
automatically
Users create more folders and messages• Mailbox grows. Split it!• Split-PublicFolderMailbox.ps1
Hierarchy connectionContent connection
Public Folder storage at no additional cost! 5 TB (100 PF mailboxes with 50 GB quota each)
Microsoft manages PF mailboxes Customers migrate to service or create the first mailbox Microsoft manages storage from there on
Cross-premise access Exchange Online users can still access on-premises Public Folders Exchange 2013 on-premises users can access Public Folders in
Exchange Online
Tenant admin can do folder management in EAC
Exchange Online Public Folders
Public folder limits
Supported limits for Exchange Online & on-premises• Max total public folder count of 10,000• Max public folder mailbox count of 100• Max users per mailbox count 2,000• Max number of messages per folder 1M• Max folder depth of 300
Public folder investment areasScaleInvest on increasing limitsHierarchy sync performance optimizations
Migrations improvementsCross-forest migrations for legacy public folders Reliability and speed
Client connectivityAccess for Outlook for Mac clients to access legacy PFsCalendar and contact folder support in OWA
Other areasAuto-split infrastructure
Backup and restore of Public FoldersSupported restore scenarios- Deleted secondary mailbox- Disconnected mailbox- Deleted folder- Deleted item
Protecting your Primary mailbox- Cmdlet deletion disallowed if secondary mailboxes present- DAG usage recommended for on premises customers
Public Folder Migration and Coexistence
• Make sure source is running Exchange 2010 SP3+ or Exchange 2007 RU10+
• Check that replication between source public folder databases is healthy
• All Public Folders cut over to Exchange 2013 together• There will be a short downtime while the migration is
finalized• Once migration completes, everyone switches at the same
time• Admin can choose to switch some users first for validation

What’s different when migrating to Exchange Online?• Add Accepted Domain + Configure routing
to Exchange Online for mail-enabled Public Folders
• Run export+import scripts for mail-enabled folders
• Run New-PublicFolderMigrationRequest with the following additional parameters:
- OutlookAnywhereHostname: OA external host name- RemoteCredential: Public Folder Admin with access to all folders- RemoteMailboxLegacyDN: LegacyExchangeDN of PF Admin- RemoteMailboxServerLegacyDN: ExchangeLegacyDN of Public Folder server- Authentication: Basic or NTLM, depending on your OA authentication
Migrating to Modern Public Folders
demo
• Exchange Online Mailboxes can access Legacy Public Folders• Requires DirSync• Supports Exchange 2007, 2010 and 2013
• Configuring Coexistence1. CAS role required on Public Folder servers (Exchange 2010 only)2. Create empty mailbox DB on Public Folder servers3. Create proxy mailbox in empty DB4. Set RPCClientAccessServer for each empty DB5. If needed: Run Export-/Import-MailPublicFoldersForMigration.ps1 scripts6. Configure Exchange Online to access on-premises Public Folders:
Set-OrganizationConfig -PublicFoldersEnabled Remote –RemotePublicFolderMailboxes ProxyMbx1, ProxyMbx2…
• Verify functionality using Outlook
Public Folder coexistence with O365
Migration guidelines• Start cleanup of existing Public Folders and
introduce alternatives • Reduce PF replicas where possible• Start to migrate all mailboxes to Exchange
2013 first, your Public Folders stay where they are today
• Start Public Folder migration sync(s)• When all Mailboxes are migrated, define a
weekend or more to lock-down the existing Public Folder structure
• Do a final delta-sync• Switch PF structure to Modern Public Folders
Modern Public Folder Planning Aspects• Does it make sense to migrate to E2013 public
folders?• Reduce content as much as possible• How many Public Folder mailboxes do you
need? Remember, minimum one mailbox per 2,000 users
• Where do you place the Public Folder mailboxes? Place the primary PF mailbox to a database that is member of a DAG!
Key takeaways• New mailbox based architecture• Single writable copy of hierarchy, multiple
read copies• Public folders in O365 for the first time!• O365 customers get free public folder
storage• Use public folders for announcements and
messaging based archival• Migrate users before public folders• Prune hierarchy before migration• Cut over migration from legacy public folders
