My company has been acquired by another company. My company has been using Office365 for email without a problem for the past 2.5 years. The new company uses Google Apps for work. They want us to migrate our email off of Office365 to Google. We are mostly running Outlook 2013 Click to Run version. I was told to use the Google App Sync tool to create our new profile and to import the data using this tool. So far this process has proven to be a problem. I have used this tool on 3 users PC's so far. It creates the profile with no problem, it copies over the inbox and sub folders under the inbox with no problem, but for some reason it doesn't copy over the Sent Items folder and content or the content in the sub folders under the inbox. I exported the sent items folder from the office365 profile to a PST to import into the Google Apps profile. It wouldn't import the items. I would get a generic popup message saying the items could not be imported. So I tried opening the PST file while I was in the Google Apps profile and tried dragging a few emails across, this didn't work. I tried doing Copy to folder into the new profile that seemed to work but it took forever for a folder that didn't have more than a years worth of emails. Then I would get an error at the end of that process. So I let the Google App Sync tool do its thing syncing the folders. I left it at 5pm came back the next morning and the tool was still syncing. So I cancelled the process and the sent items folder I had copied over disappeared. Now the 3 users I migrated over is having sync problems, where the sync tool is constantly syncing their emails and it seems to never end and they are not receiving the emails that are being sent to them. So good thing I left their Office365 email profile in outlook. Now understand the office365 profile and Google profile are 2 separate profiles they are not combined. So if anyone has been threw this nightmare and has successfully migrated please let me know what I'm doing wrong. I have 1 week in order to migrate 120 users.
