Thank you very much. I particularly appreciate being warned away from the scammer who offered to fix my problem with a call to a 901 number.
Your message explains why I don't see more-than-one-year-old email when I do a search in Outlook for "Current mailbox", but I do see it when I do the same search for "All Mailboxes" (which probably involves an internet search of my remote online archives).
Is this correct? Will I have access to all my old email as long as I remain a Microsoft 365 subscriber for my office account?
Is there any way that I can also store my old email locally?
How do I confirm that I have an Online Archive? This is a big plus for Microsoft 365 IMO.
PS: I was led to Auto Archive by links in the Outlook client software's help function to pages on the Microsoft site. If Auto Archive is really obsolete, it would be helpful to go back and fix those links, or fix the pages to explain that Auto Archive is obsolete.
