Hi Grace Yin , 

 

The Backup only clear your transaction logs files, you will need to know what files or folders are consuming more space to figure out the root cause.

 

For example, if your database is very big you need to see what mailboxes are inside and their size.

Hi Nuno,

 

Folder "Mailbox Database 1872985310" in C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\ is very big. What is this folder for? How to clean up to free space? Folder "log" is also big.

 

Please advise!

 

Thanks!
