GSMME system requirements

G Suite Migration for Microsoft Exchange

You must meet the following system requirements before using G Suite Migration for Microsoft® Exchange (GSMME).

If you have the legacy free edition of G Suite, upgrade to G Suite Basic to get this feature. 

Component Requirements
Source mail server

One of the following mail server environments:

  • Microsoft® Exchange Server 2000, 2003, 2007, 2010, 2013, or 2016.

    Note: Exchange Online is not supported.

  • Any RFC 3501-compliant IMAP server, including Exchange, Novell® GroupWise®, Cyrus®, Courier®, Dovecot®, SunMail®, Zimbra®, or Gmail.

In addition, you need an administrative account on your server that has permission to read each user's mailbox. In Exchange, the permission Receive As is sufficient.

GSMME client machine

One of the following operating systems:​

  • Windows® Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, or Windows Server 2016.
  • Windows Vista Business SP1 or later.
  • Windows 7, Windows 8, and Windows 10.

In addition, the following is required when migrating from Exchange or PST files:

  • Microsoft Outlook® 2003, 2007, 2010, 2013, 2016, or 2019 (32-bit only).

    Note: Click-to-Run versions are supported, except for Outlook 2010.

  • 64-bit versions of Outlook aren't supported.

We recommend that you use the latest updates for both Windows and Outlook.

Can I run GSMME on the Exchange server?

No. It's strongly recommended that you run GSMME on a separate client machine.

Does GSMME work in a hosted Exchange environment?

Yes. GSMME does work in a hosted Exchange environment but you need to be aware the profile is created differently.

GSMME accesses Exchange mailboxes using an administrator profile. If you configure GSMME with the server hostname/user option, GSMME creates a profile using these settings and uses the profile to access the mailboxes.

With hosted Exchange environments, and other complex network setups, direct MAPI access from Outlook to Exchange isn't possible. In this case, when you create a profile from Outlook using the Outlook wizard, GSMME uses Outlook Anywhere (also called MAPI/RPC over HTTP) to make sure Exchange is accessible from the profile. Using Outlook Anywhere is the best way to connect to hosted Exchange services.

Can I migrate from a hosted Exchange environment if I don't have administrator access?

No. Administrator access is required.

If you aren't an administrator but want to migrate from Exchange or Outlook, you can use G Suite Migration for Microsoft Outlook (GSMMO).
