Background/Overview
Since users are migrating in waves, there will be a period of time when users that have migrated and users that have not migrated are coexisting and collaborating. During this time, you should follow the process below when sharing files from your OneDrive.
Process
When sharing from the OneDrive of a Migrated User to a Non Migrated User, after clicking Share, type out the full email address of the person you wish to share with. Do NOT choose any of the options that are provided to you. Note: If you are not sure if the person you are sharing with has migrated or not, you can always enter their email address to make sure they will get the link.
Once the full address has been entered, press Enter to select the entry before clicking on Send. If you click Send before pressing Enter, you will receive the following error.

If you receive this error, delete the typed address, re-enter it, press Enter and then press Send.
