I'm working with a school that uses Office 365 but don't use the Exchange mail box function. They have used GroupWise for around 15 years and are happy with it and see a change as being massive. However, there is new function that they want to use within 365 that demands an exchange mailbox.

Migrating teachers mailboxes will be massive task. They are great collectors :-)

I've wondered about the possibility of setting up 365 mail as an IMAP account inside GroupWise and making that the default account until we migrate mail. Teachers could maybe migrate their own by moving mail they want to keep into knew folders within the IMAP account. That would certainly save me some work. :-)

I open to suggestions especially any that allow us to keep GroupWise. :-)
