CAUSE
This problem may occur if all the following conditions are true:
- You send an e-mail message to a large dynamic distribution list.
- The Exchange Streaming Database is stored on a network drive. For example, the Exchange Streaming Database is stored on a Network Attached Storage (NAS) device.
Note The Exchange Streaming Database is also known as the .stm database file. - The Installable File System (IFS) file in the Exchange Streaming Database has more than 896 fragments.
- The Exchange Installable File System (ExIFS) service tries to create a temporary file in the folder where the Exchange Streaming Database is located.
If you send an e-mail message to a large distribution list, the property stream may be sufficiently large that the Exchange transport must write the property stream to an IFS file instead of to the memory buffer. If the IFS file has more than 896 fragments, ExIFS converts the scatter list to "large buffer" mode. Then, ExIFS moves the scatter list to a temporary file that is in the same folder as the Exchange Streaming Database. When the Exchange Streaming Database is located on a network drive, the call to create the temporary file may fail.
Note A
scatter list keeps track of the offsets and the length of each fragment of an open IFS file that are "scattered" in the larger Exchange Streaming Database.
