Hi @IniobongNkanga-8038 ,

Welcome to the Microsoft Q&A platform!

According to your description, it sounds like a complex situation involving OneDrive and Outlook settings. Let's break this down step by step to help you resolve the issue:

Step 1: Confirm OneDrive Sync Settings

1. Open OneDrive Settings:
   • Right-click the OneDrive cloud icon in your system tray and select "Settings."
2. Disable OneDrive Sync:
   • Go to the "Account" tab and choose "Unlink this PC." This will stop OneDrive from syncing completely.
3. Disable Specific Folder Sync:
   • If you still wish to use OneDrive for other purposes, go to the "Choose folders" button (under the "Account" tab) and uncheck any folders that contain your Outlook data (e.g., PST files).

Step 2: Verify Outlook Settings

1. Check Data File Location:
   • Open Outlook > File > Account Settings > Account Settings > Data Files tab.
   • Ensure that your data file (i.e., .PST or .OST file) is located in a directory that is not synced by OneDrive.
2. Check POP Settings:
   • Confirm with your email provider that the POP settings are correctly configured to ensure emails are not deleted from the server after they are downloaded.
3. Back Up Contacts and Emails:
   • Export your contacts and emails to a separate PST file for backup. Go to File > Open & Export > Import/Export > Export to a file and choose "Outlook Data File (.pst)."

Step 3: Check OneDrive Business Account and Multiple Microsoft Logins

1. Check if Outlook is Syncing to the Wrong OneDrive Location:
   • Sign in to both OneDrive accounts and verify where the Outlook data files are being stored.
   • Ensure the correct OneDrive account is linked to your current Microsoft 365 subscription.
2. Verify Microsoft Account Logins:
   • Make sure Outlook is logged into the correct Microsoft account that matches your 365 subscription.
   • Go to File > Office Account in Outlook to check the logged-in account.

Step 4: Delayed Sync Issue

1. Check OneDrive Status on Startup:
   • If OneDrive starts syncing on startup, you can delay its startup or disable it from running automatically when you turn on your computer:
   • Press Ctrl + Shift + Esc to open Task Manager.
   • Go to the "Startup" tab and disable OneDrive.

Recovery Steps

1. Recovery of Lost Contacts and Emails:
   • Since you mentioned that your emails and contacts were lost on August 30, 2024, you can try to restore your OneDrive to a previous version:
   • Go to the OneDrive web app, click on the gear icon, and choose "Options".
   • Under "Restore your OneDrive," choose a date before the issue occurred and restore.
   • Alternatively, check the "Deleted Items" and "Recoverable Items" folders in Outlook to see if any of the lost content can be recovered.
