It appears that you’re encountering issues with Outlook 365 desktop when trying to add a IMAP account. The creation of a “ghost OST” file and other problems can be frustrating. Here are some steps you can try to resolve the issue without creating another Outlook profile:
Repair Office 365 Installation:
- First, try repairing your Office 365 installation. This can often fix issues related to Outlook. To do this:
- Open the Control Panel on your computer.
- Go to “Programs” > “Programs and Features.”
- Find Microsoft Office 365 in the list, right-click it, and select “Change.”
- Choose “Quick Repair” and follow the on-screen instructions.
Check for Updates:
Ensure that your Outlook 365 is up to date with the latest updates and patches.
Disable Cached Exchange Mode:
- Sometimes, issues with OST files can be resolved by disabling Cached Exchange Mode. To do this:
- Open Outlook.
- Go to “File” > “Account Settings” > “Account Settings.”
- Select your email account, click “Change,” and then uncheck “Use Cached Exchange Mode.”
Remove Phantom OST Files:
- If there are indeed phantom OST files causing problems, you can try to manually delete them. Make sure Outlook is closed before doing this.
- Check for Duplicate Profiles:
- Recreate Outlook Profile (if necessary):
If none of the above step’s work, you might need to recreate your Outlook profile. This is often a last resort but can sometimes resolve stubborn issues. Make sure to back up any important emails or data before doing this.
- Navigate to the folder where OST files are stored. The default location is typically:
- C:\Users<your_username>\AppData\Local\Microsoft\Outlook
- Delete any OST files that shouldn’t be there.
- Ensure you don’t have duplicate Outlook profiles. Sometimes, this can cause confusion. You can manage profiles through the Windows Control Panel.
