Google Workspace Migration for Microsoft Exchange (GWMME) migrates email, calendar, or contact data from Microsoft Exchange, an IMAP server, or a PST file to your Google Workspace account. Consider the following data and whether it's migrated, when you're setting up a migration to Google Workspace with GWMME.
Migration status of source dataEmail
|Supported email features||Notes|
|Email messages||All email messages in top-level folders are migrated. A top-level folder is any folder that is at the same level as your inbox folder.
You can also choose to migrate email to Google Vault.
|Email state, such as read or unread|
|Deleted items||Migration is optional. Deleted items are labeled Trash in Gmail.|
|Folders||Folders map to labels in Gmail. You can exclude specific top-level folders from a migration by individually selecting them. If you exclude a folder, its subfolders are also excluded.
Folders with folder paths longer than 225 characters aren’t migrated. The messages inside the folders are also not migrated.When you set up your migration, you can exclude specific top-level folders. For details, go to Chapter 6 of the GWMME Admin Guide.
|Junk email||Migration is optional. Junk email is labeled Spam in Gmail.|
|Public folders||You can migrate content from public folders to Google Groups. For details, go to Migrate public folders.|
|Large messages & attachments||Most attachments are migrated, except when the message plus attachment is larger than 25 MB, or when Gmail blocks certain types of file attachments, such as executable files. For details, go to File types blocked in Gmail.|
|Message flags||Flags appear as stars in Gmail.|
|Shared mailboxes||Shared mailboxes migrate as regular mailboxes. You can turn on Gmail delegation after the migration. For details, go to Turn Gmail delegation on or off.|
|Subfolders||How a subfolder migrates depends on its location:
|Unsupported email features||Notes|
|Posts in mailbox folders|
|Importance levels of messages|
|Rules||Rules (both server and client) aren’t migrated but you can create equivalent filters in Gmail.|
|Signatures||Signatures aren’t migrated but you can recreate them in Gmail.|
|Category definitions or assignments|
|Supported calendar features||Notes|
|Default calendar, including events, descriptions, attendees, event reminders, and locations||If you’re using an exported or archived PST file, all calendars are migrated as Other calendars instead of as the default calendar. You can avoid this by using an Exchange server migration for importing calendars. For details, go to Migrate data from Exchange.|
|Calendar events||A warning message appears in the log file if you import events for users who aren’t the original organizer or initial attendee for the event. However, the event successfully migrates and the target user is shown as an attendee of the event in Calendar.|
|Other calendars||Other calendars are migrated for the owner, but not for other users who have access.|
|Free or busy status|
|Calendar resources||Use a comma-separated value (CSV) file to migrate calendar resources (such as meeting rooms). You can also use the file to change event attendees’ email addresses to Gmail email addresses. For details, go to Create a mapping CSV file.|
|Unsupported calendar features||Notes|
|Rich content in event descriptions||Rich text descriptions aren't imported. In Microsoft Outlook 2016, descriptions are converted to plain text.|
|Tentative or Out of Office status||Any special status for calendar data is not migrated.|

|Supported contacts features||Notes|
|Personal contacts||Includes all fields|
|Notes||Notes in contacts are migrated as plain text. Notes larger than 16 KB are truncated.|

|Contact folders||Separate contact folders don’t migrate. Instead, all contacts from all folders are migrated. You can reorganize them using labels.|
