Please make sure to download from a trusted source and update to the latest, most secure version	Make sure you're using the latest version of GWMMO. For details, go to Download & install GWMMO.

User has not agreed to the Gmail Terms of Service	The user must sign in to Gmail and accept the Terms of Service before proceeding.
MAPI_E_PST_SIZE_EXCEEDED 0x8004060c	Usually indicates a PST file exceeds the maximum size supported by Outlook. Consult your Microsoft documentation for information about supported PST file size.
0x8004010f 0x80070005	You might see this error if: You don’t have privileges to access the PST file being migrated. GWMMO can’t access the PST file. GWMMO requires both read and write access to the file.
0x80040109	Another process is accessing the PST file being migrated or the Outlook profile at the same time as GWMMO. Make sure that any other MAPI application that can access the profile isn't running at the time of the migration. Make sure that anti-virus, back-up, or desktop search software excludes PST files from their scans.
0x80041066	A message was skipped because it exceeds the Gmail message size limit. If you want to move the message to your new account, you must do so manually (for example, add the file to Google Drive). Related topics: Send attachments with your Gmail message Upload files to Drive
0x80070035	The PST file that is being migrated has an incorrect path. The path specified is a network share (\\servername\share\...) and is not valid. Copy the PST file to the local drive (usually, C:) and migrate from there.
0x80070036	You might see this error if the user conducting the migration has insufficient privileges to access the PST file or GWMMO is unable to find the file. Make sure that GWMMO has both read and write access to PST files.
0x80072ee2	GWMMO is experiencing temporary errors. Select Migrate only new data and try the migration again. For details, go to Choose what Outlook data to import. The error might also be due to network timeouts. Changing the registry keys might help resolve this. For details, go to Error code 0x8007065e. Related topic: Migrating large messages can time out over a slow connection
0x8007065e	You might see this issue if the network timeout registry entries are created with a registry data type other than REG_DWORD. To check the data type: Using the Registry Editor (regedit), navigate to HKEY_CURRENT_USER\Software\Google\Google Apps Migration\Other. Check that all entries are Type: REG_DWORD. If needed, consult your Microsoft documentation on how to change the registry data type.
