Exchange constantly writes DB Logs to disk. These logs only get cleared when a backup is done.
If you need to clear those logs without a backup, use the following commands (if the DB log files are on the d: drive):
Open a cmd box with admin rights
diskshadow
add volume d:
begin backup
create
end backup
That's it. You should now have much more free disk space.
Somethimes, the default maximum message size (including attachments) is not enough (30 MB is the standard). To increase this to 100 MB, do the following:

Get-TransportConfig | ft MaxSendSize, MaxReceiveSize
Get-ReceiveConnector | ft Name, MaxmessageSize
Get-SendConnector | ft Name, MaxMessageSize
Get-Mailbox Administrator |ft Name, MaxsendSize, MaxReceiveSize
Then set it to 100 MB for all components:
Set-TransportConfig

When I wanted to install CU11 for Exchange 2016, at the Prerequisites Check, I got the following error message:
