Please review the contents of your Mailbox and folders to find received and sent items that are no longer needed. Removing these items from the account will help your Office 365 begin with less clutter, and can help your account migrate more quickly.

Overall Account Size
After you have done your account cleanup and either saved to disk or deleted messages in your account or archive that are larger than 25 MB, it is worth looking at the overall size of what remains.
