What is/isn't migrated, what terminology is different and what will I do differently in Outlook

The following tables show Google's names for things and highlights where Outlook has different terminology or does things differently. It also provides a succinct guide as to what is migrated and what is not along with advice on workarounds.

What is/isn't migrated and what is it called in Outlook?

Google name Outlook name Migrated? Migration issues/notes
Emails Yes Some old emails show as having arrived on the wrong date
Labels Folders and Categories Yes ​​Google labels have been migrated across as Outlook folders. However, messages with multiple labels in Google will be migrated across as a single message, which will be filed into the folder in Outlook which corresponds with the first label that was added to it. Those emails, however, will show multiple categories (Outlook's equivalent to Google labels).

If the other labels were only used as subsequent labels (i.e. were never added to an email as first label) folders are not created for them.

Note that although category labels will migrate across, the associate colours don't, so you may need to spend some time tidying this up.

Nested labels Sub-folders Yes
Tasks Tasks Yes
Stars Flags Yes Anything that was starred in Google has been migrated across as though sent by the sender as important (thus "!"). There is nothing that can be done about this.

If you want to find all the emails that you had starred in Google, you can search - see Microsoft's advice on searching for important messages - and then use Outlook's flag function to assign them flags - see Microsoft's advice on using flags.

Delegated mailboxes Shared mailboxes Yes Permissions attached to shared mailboxes (i.e. who can do what) can't be migrated until the migration is complete. Therefore, there may be a slight delay on day 1 whilst a script is run to add these permissions post-migration. This may mean that you might not be able to access one or more shared mailbox(es) on 10 July until the permissions script has finished running.
Filters Rules/ Inbox sweep rules No You will need to set these up again in Outlook - see Microsoft's advice on creating and using rules.
Canned responses Quick parts (desktop) / My Templates (web) No Quick parts are only available in Outlook Desktop.
Email forwarding Rules / Forwarding No You will need to set these up again in Outlook - see Microsoft's advice on creating and using rules.
Out-of-office Yes and no! Depending on how you use your out-of-office message (i.e. leave permanently on and change the dates or only switch on when out of office) you might find that it is turned on post-migration even if it wasn't enabled in Google.

If your out-of-office is on in Google it will remain on in Outlook, although the text may have changed to a single line of standardised text, where it had previously been formatted with spaces and paragraphs.

You should therefore check to ensure that your out-of-office is correctly set.

Signatures Yes... ...though some may find that the signature did not migrate (or it migrated but does not appear automatically in new emails), so you will need to check and possibly recreate your signature prior to sending emails from Outlook. Note that you will need to check both desktop and online versions of Outlook if you are using both and add in both.

To check or add a signature in Outlook Online:

  1. Click on the Settings cog (top right-hand corner) and select Mail from the Your app settings section.
  2. In the Options pane select Email signature.
  3. Add your signature and put a tick in the top check box.
  4. Select Save and close both the Options and Settings panes.
Contact Groups Contact lists No If you set up your own contact lists, you will need to set these up again in Outlook.
Spam Junk email No Outlook's Junk function will need to learn what you consider junk, so you should check your Junk Email folder regularly for the first month or so. You may also receive more junk in the short term, whilst Outlook works out what you consider to be junk.
All mail All Google mail Yes
Calendar meetings and events Appointments/ Meetings/All day events Yes The RSVP status of meetings (Yes, No or Maybe) will not be migrated. Some meetings may be duplicated (if part of a series and one or more was subsequently moved or amended). See above tables for further advice.
Delegate calendars and viewing access Shared calendars Yes Permissions attached to shared calendars can't be migrated until the migration is complete. Therefore, there may be a slight delay on day 1 whilst a script is run to add these permissions post-migration. This may mean that you might not be able to access one or more shared calendar(s) on 10 July until the permissions script has finished running
Other calendars No You will need to add your frequently viewed calendars again.
Rooms and other resources Yes
Google Drive/Docs OneDrive No You can continue using Google Drive/Docs (including any shared documents) for a while. However, the service will be withdrawn at some point (as yet undecided). In meantime, you could start using OneDrive.

What do I need to do differently in Outlook?

In Google you could... In Outlook you will...
...see the meeting title, time, location and attendees for all open meetings. ...see the meeting title and location only.
...select Yes, Maybe and No in response to calendar event invitations. ...select Accept, Tentative, Decline and Propose another time in response to calendar event invitations.
...transfer ownership of a calendar event to someone else. ...ask the other person to create a new event in their calendar and invite the attendees again; the old event should then be deleted to preclude confusion.
...edit calendar event details if you had been invited to the event. ...ask the event organiser to make any updates to an event.
...duplicate a calendar event. ...in Outlook desktop, click on a meeting, press <Ctrl> + C, click on a new time and press <Ctrl> + V.
...see if you had been blind copied (Bcc) into an email. ...not see that you have been blind copied.
