I used the Migration Adviser to start an IMAP migration for a single email address from Rackspace.Select the option to transfer your information 'From a Windows PC', then click Continue. IMAP is available by request only and for applications using OAUTH authentication. You can continue using your email as usual while the program is.
Big Sur Mail Search is completely broken, doesn’t find anything. Mac outlook search not working after migration Manually Back up Outlook Emails on Mac to OLM Archive File.
