How are "Starred", "Important", and items sent with "High Importance" handled when migrating from Google to Exchange?
Any items designated with a 'Starred', 'Important', or items that have a 'High Importance' tag that was set from an email client that supports a 'High Importance' designation have unique behaviors when being migrated from Google to Exchange.
Starred Items: Items marked as 'Starred' will have a red flag designation in the destination mailbox, indicating that this item was marked for follow-up.
High Importance Items: Items sent with 'High Importance' through an email client will have that status maintained during the migration.
Important Items: Items marked as 'Important' will have no discernable markings within the destination mailbox. These items will display as a normal mail item.
When migrating items from Google, if there are any tags associated with the item, those tags will supersede any other labels that may be associated with it.
