Hi Friends,

Hi Ranjit,
Thank you for your question. 
Based on my research, the causes can be: 
1.Pipeline tracking log is enabled and it takes some space；
2.Large MaxDumpsterSizePerStorageGroup limitation. 
To troubleshoot the issue, we can take the following steps. 
1. Disable the Pipeline tracking log if you do not need it 
    a. Check if Pipeline Tracing enabled by command:
     Get-TransportServer | FL name,*pipeline* 
    b. If enabled, please use the following command to disable it 
    Set-TransportServer “Server Name” -PipelineTracingEnabled $False    
2. Reset the MaxDumpsterSizePerStorageGroup limitation 
    a. Run “Get-TransportConfig” and ensure the following 
    MaxDumpsterSizePerStorageGroup is in MB’s and not GB’s     
    MaxDumpsterTime : 7.00:00:00 
    b. If not, we run the following command to modify: 
    Set-TransportConfig -MaxDumpsterSizePerStorageGroup <size> -MaxDumpsterTime    <timespan> 
3. If it still does not work, we can manually reset the Mail.que and then monitor if it is still increasing: 
    a. Stop Transport service on the server. 
    b. Move the folder C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Queue to other place. 
    c. Start the Transport service on the server. 
    d. If there is no related issue, just delete the previous Queue folder. 
    e. Monitor the new Queue folder size. 
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
