Dear Sir,

I have a new win 11 pc with Microsoft 365 for the past two months and I am now having problems with my Outlook Classic.

I see from today suddenly Outlook Classic deleted emails are returning back even if I have deleted them several times they keep coming back.

When I switch on the pc I am able to open Outlook Classic normally but each consecutive time afterwards it doesn’t open anymore I therefore have to switch off or use Task manager to end the Outlook Classic. Or otherwise keep switching off and on the PC to get outlook classic to open up again.

I have also noticed at the TaskBar app of Onedrive – personal the following: This file in in use This file is open by another program and can’t be synced. Once the file is closed, we can sync it.ggini1@tin.it – Outlook GG.pst

I am not able to understand and locate the place and how and where I can close this file ? maybe this is the problem affecting causing the above irregularity on my Outlook classic?
Thank you
Please help
 

Solution
Julian — that OneDrive message is expected if the PST file is inside your OneDrive folder.
A .pst (Outlook data file) is kept open/locked while Outlook is running, so OneDrive can’t sync it and keeps showing “This file is in use”. The real fix is: don’t store an active PST in OneDrive (it can also cause corruption).
Here’s the simplest way to remove that warning permanently.

Simple fix (recommended): move the PST out of OneDrive​

1) Close Outlook completely​

  1. Close Outlook.
  2. Press Ctrl + Shift + EscTask Manager
  3. End task Microsoft Outlook (OUTLOOK.EXE) if you see it.

2) Create a non‑OneDrive folder​

Create this folder:
  • ...
That message from sgsmy77 does not require any action from you.
What happened is almost certainly this:
  • The WindowsForum email notification included a quote that accidentally contained text from a different conversation/thread (the part about “cookjia.com”).
  • It’s confusing, but it’s not an “error” on your PC and it’s not related to your Outlook/OneDrive problem.

What you should do​

  • Ignore it unless the user is directly asking you something you recognize.
  • Do not click any strange links or download anything from that email if it contains unexpected URLs.

When it would require attention​

Only if the email:
  • asks you to log in and confirm password/payment, or
  • includes a suspicious link/attachment, or
  • claims your account will be closed, etc.

If you want, I can confirm 100%​

Copy/paste the exact text of the message you received from sgsmy77 (or upload a screenshot of the email content).
I’ll tell you whether it’s just a mistaken quote/notification or something suspicious.
As of what you’ve shown, it looks like a mix-up/irrelevant quote, not something you need to fix.
