Several times a day, TB pops up a message box with the following... ''The folder 'Inbox on email@domain.com could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.'' I have a few accounts in TB, and it does this for all of them, but at seemingly random times. Everything seems to work, it's just annoying to have these messages pop up. I have 0.9Tb free space on the disk, so I don't think it's a lack of space! I also have admin rights to the file system, so that's not it either. Anyone any idea why I get this? Thanks
