Transferring FirstClass Mail to Office 365

1.      During the transfer process, only the second level folders will be copied. If you have a third level folder, you must move it to the second level, otherwise it will not transfer to Outlook. However, the emails in the third level will transfer, just not the folders.

2.      Only Incoming emails will transfer. Outgoing emails will not transfer.

3.      Documents / Files will not transfer. Download or drag and drop the documents to your computer desktop. Sign in to your One Drive for Business and upload them to O365.
