Need to Combine C: and D; Drive because C: runs out of space

[ninsights]

Computer : HP Omen laptop
Operating System: Windows 10

My laptop hard drive is structured with a C: and D; drive. D has lots of space but C: has very little space since Windows, Office 365, Micrsosoft Teams and email files all insist on being on C. Any program that I could move to the D drive has already been moved. My C: drive is being taken up all by Microsoft programs.

I have sooooo much space on D but Windows 10 and Outlook 365 and email OST/NST files can't be redirected to D. I've already asked Microsoft if this is possible and they said no. None of these Microsoft programs can be put on D:.

I have struggled with space on C for the last 10 months and now I really need to be able to combine C and D into ONE C drive to solve my storage issue. The laptop performance is great. It's just hampered by the size of the C: drive.

Is there a way to make my entire drive one big C: drive so I don't have an issue with running out of space on C: ?  My family members also have HP laptops and theirs came all as one C; Drive so they don't get this issue.

Any help greatly appreciated.

hi

you have an SSD disk, and a HDD hard disk
As far as I know, that's impossible!
I doubt that only one or two programs use all the disk space
So, see if possible to clean the SSD disk as much as possible, if there is nothing left to move!
your only option would be to replace this ssd, with a larger one if possible
so this is done?
