Before your Exchange mailbox is migrated to Office 365, there are a few things you should do to make the transition as smooth as possible.
Empty Deleted Items and Junk Email
Please empty your Deleted Items folder and Junk Email folder by right-clicking on each folder and choosing Empty Folder.


Update Login Name
Check to make sure that your user name on your computers and mobile devices is set to login@bu.edu and NOT as AD\login (where login is your BU login name).
Mac Users
In Outlook, to check your login name, go to Outlook >> Preferences >> Accounts to view your user name:

If you use Apple Mail, there are no steps you can take prior to migration. We expect you will need to delete and re-add your account from Apple Mail AFTER being migrated.
Windows Users
To check your login name, go to Outlook >> File >> Account Settings >> Account Settings (again) to view your user name:

iOS Users
To check your login name, go to Settings >> Mail, Contacts, Calendars >> Exchange >> Account
The email and username should be login@bu.edu:

Android Users
Android 5.0+ (Lollipop and newer) users can update their login name by tapping the Menu icon in the mail app, and choosing Settings, then your Exchange Account (login@bu.edu) and scroll to the bottom to select Incoming Settings
