Using New Outlook on Windows for professional communication and productivity
Hello Gerry,
Thanks for bringing this up. I understand how frustrating it can be when your older emails suddenly stop appearing, especially when the instructions you find online don't match what you see in Outlook.
Since you're using New Outlook with an IMAP account, I'd like to check its offline email settings first.
New Outlook has an option that controls how many days of email are stored locally. If this is set to seven days, it could explain why you're no longer seeing older messages in the app.
Could you please check the following?
Open New Outlook and select the Settings (gear) icon.
- Select General, then Offline.
Look for Days of email to save.
If it's set to 7 days, try changing it to 30 or 90 days.
Also check Folders to save and make sure your Inbox is included.
Save your changes and give Outlook some time to synchronize.
You can find Microsoft's guidance here:
How to work offline in Outlook for Windows
If the older messages still don't appear, please sign in to your email provider's webmail through a browser and check the same Inbox.
If the older messages are visible there, they are still available on the mail server, and the next step is to investigate how New Outlook is synchronizing them. If they're missing there too, the issue may be related to the mailbox or email provider rather than Outlook.
Could you let me know whether you can see the older messages in webmail and what the Days of email to save setting was originally set to?
Those details will help me narrow down the cause without asking you to reset Outlook or remove your account unnecessarily.
Kind regards,
