Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Arleen,
I’m very sorry to hear about this, especially given the personal importance of those emails. One important point is that removing an email account from Classic Outlook normally does not delete the actual email account; it removes the account and its locally cached content from Outlook.
Since this appears to be an RCN email account, I would first sign in directly through your email provider’s webmail and check whether the older folders and messages are still on the server. Also, please do not delete or modify any Outlook data files on the computer. Search for existing .pst files, as POP accounts and archived Outlook mail may be stored locally in these files and can be reopened through File → Open & Export → Open Outlook Data File.
Because this happened during a Microsoft Support session, I would also follow up on the existing support case and request escalation, clearly stating that previously available folders and historical mail disappeared after the account was removed and re-added.
For privacy, I recommend removing your phone number and partially visible email address from this public post.
Thank you, and feel free to respond back for more assistance.
