If you have decided to migrate GroupWise to Outlook then Export GroupWise software is an excellent option available that you can opt for. The main functionality of the software that makes it different from other GroupWise to Outlook converters is that it works with PROXY USER that allows GroupWise users to authentically transfer user mailbox (using OAuth technique) rather than MAILBOX ENABLED USER where you have to enter password of every user when you Export GroupWise to Outlook.

Suppose you have 1000 mailboxes in GroupWise, and you wish to convert them to Outlook, then in that case you don’t need to enter password for ever user if you have created proxy user but it becomes difficult for users to perform the same task if you have mailbox enabled user.
