Notify your users that they should expect to see this account as the owner of their public folders. Consider setting an informative display name for this account.

Source Exchange 2010 Account

To set the source administrative account perform the following steps;

Open Migration Manager Console
Right click Source Exchange Organization node of the Migration Manager Console management tree.
In Add Source Organization Wizard on the Specify Active Directory Domain page provide or change, if necessary, the account credentials in the Logon As area and finish the wizard. This account will be used by MAgE for public folder synchronization.

NOTE: Consider, in case you decide to change account in Mailbox Migration Job or Calendar Synchronization Job properties later, this account for access to Exchange will be used instead the source administrative account you specified using Add Source Organization Wizard. To avoid any issues, it is recommended to select one administrative account to use.

IMPORTANT: The account assigned to be a source administrative account used by Migration Agent for Exchange should have a mailbox.

The following permissions are required for source Exchange 2010 administrative account used by Migration Agent for Exchange during public folder synchronization:

Permission	Used for	Used by	How to Grant

Considerations

Refer to Specific Case Workarounds for instructions on how to resolve the specific cases related to public folder hierarchy changes.

Before you migrate public folders to Microsoft Office 365 keep in mind the following cases:

During synchronization of pubic folders with Microsoft Office 365 Exchange Online, MAgE is unable to set the message owner (creator) correctly for items in folders. The administrative account becomes the creator of the message instead of the actual mailbox owner. This causes unwanted effects on the target. For example, the user cannot modify and delete their own migrated messages unless they have Owner permissions on the containing folder. This behavior is a result of Exchange and Office 365 architecture aimed at preventing security risks.
A single MAgE instance performs all migration to Office 365.
To sync the source SMTP public folder address, you need to add a custom email domain as an accepted domain for your target Exchange organization. Then, you could sync proxy addresses using ProxyAddresses parameter of Sync-MMExMailPublicFolder.
The migrated public folders always inherit the client permissions from this root folder. To avoid granting unnecessary privileges, make sure that the client permissions for the target root folder are granted to the administrative account only before starting the migration.
MAgE cannot automatically handle the following change in public folder hierarchy in some specific cases. Refer to New top-level public folders added for details

Refer to Specific Case Workarounds for instructions on how to resolve the issues related to public folder hierarchy change.

Public folders matched with deleted (soft or hard deleted) public folders by default are moved to source or target Migration Manager Recycle Bin public folders. If the Migration Manager Recycle Bin public folder does not exist , it will be created automatically. Refer to The public folder deleted for details.

Mail-enabled source folders are synchronized as non-mail-enabled to Office 365. As a workaround, use Sync-MMExMailPublicFolder to make the target folders mail-enabled and set directory properties for them.
To ensure permission synchronization you should set object matching for migrated by Quest Migration Manager for Active Directory (Microsoft Office 365) mail-enabled universal security distribution groups using Set-MMExGroupMatching cmdlet.
