Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Ishaq,
Since mid-2023, Microsoft has gradually moved Outlook storage into OneDrive, reducing the capacity for personal stuff. This is the route cause of your problem. Apparently, they told everyone but I don't remember!
To disconnect OneDrive (best on a PC/Laptop), I downloaded all of my files/folders to my PC.
Then, I did this:
Open OneDrive settings (select the OneDrive cloud icon in your notification area, select the OneDrive Help and Settings icon, then Settings.)
Go to the Account tab.
Select Unlink this PC.
Now, I backup to an external drive and I use Google Drive for my folders/files that I want to share between devices BUT that has to be done manually.
I backup my mobile devices to the manufacturer's cloud, in my case Samsung.
Trust that this helps you.
