Very common trouble on corporative network that have
laptop/computer with small hard drive or small SSD same as used by several
persons especially if are working on Outlook
As example HP Elite Book Revolver 810 G1 (hard drive 120 GB)
have 200 MB Free Space
First start any Space Analyzer
like SpaceSniffer as Administrator to have access system and users folders and
receive actual information. If you will see lot off Application Data that have
big size it’s mean or probably .ost (Outlook) file or personal data. Remember - if .ost file have size 50 GB and more user can't send/receive e-mail. Same as from 25..30 till 50 GB can have trouble send/receive functions. We can
delete .ost files use PowerShell script: OST_Delete.ps1

Same can have free space profit by delete Search database (can
have size 50 GB)
c:\>sc config wsearch start= disabled
c:\>sc stop wsearch
c:\>del C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb
and disable Hybernate mode (profit – 2..8 GB)
c:\>powercfg.exe /hibernate off
don’t forget check and clean if need “C:\Windows\ccmcache” and
windows update folder same
P.S. Below start powershell
script from command line and auto request UAC window for start as administrator.
