Mail data | Migrated to G Suite | Notes |
| Email messages | ✅ | All email in top-IeveI folders is migrated. A top-level folder is any folder that resides at the same level as your Inbox folder. You have the option to exclude specific top-level folders from migration. For more information, see Step 3: Select the data to migrate. |
Email state (read versus unread) | ✅ | |
| Folders (Labels in Gmail) | ✅ | Folders map to labels in Gmail. You can elect to omit top-level folders from a migration. If you omit a folder, its subfolders are also omitted. There is a 255 characters limit per label. If you're migrating a folder with a title that's over 255 characters, the mail will still migrate, but it will be put with the prior label. |
| Subfolders | ⚠ | Subfolders in your Exchange inbox don't migrate as nested labels in Gmail. Instead, the subfolders appear as Inbox/foldername in an unnested state. |
| Junk email | ✅ | Migration is optional. Junk email is labeled "Junk email" in Gmail. |
| Deleted items | ✅ | Migration is optional. Deleted items are labeled "Trash" in Gmail. |
| Public folders | ✅ | For details, see Migrate public folders with GSMME. |

Calendar
Calendar data in Exchange | Migrated to G Suite | Notes |
| Default calendar | ✅ | Includes all events, descriptions, attendees, and locations. If you are using an exported or archived PST file, it's not possible to identify the primary root folder for Calendar and Contacts. Therefore, all calendars are migrated as additional calendars into G Suite Calendar, instead of any default calendar. You can avoid this by using PST migration for mails only and using Exchange server migration for migrating calendars. |
| Additional calendars | ✅ | Shared calendars are migrated for the owner, but not for other users who have access. |
| Event reminders | ✅ | |
| Free / Busy status | ✅ | Only other G Suite users can see the free or busy status in Google Calendar. |
