|Message:||Error error code starting Storage Group name on the Microsoft Exchange Information Store. error message.|
This event is logged if the Microsoft Exchange Information Store service detects an error when mounting the mailbox stores and public folder stores of a storage group.
This problem can occur if Exchange has used all the available transaction log files. Exchange uses transaction log files that are numbered sequentially. The transaction log files start with E0100001.log, and then increment sequentially to E01ffff0.log. When the last transaction log is filled, the Microsoft Jet database engine returns error -519 (JET_errLogSequenceEnd) to the store. However, the store keeps the databases mounted, although database transactions cannot occur.
The maximum number of transaction log files that can be generated in a single sequence is 1,048,560 (0xFFFF0). Typically, it will take several years of operation before this many log files will be generated.
