Additional note. I have found some errors which might just be coincidence.
With IMAP4SVC diagnostic logging on Maximum the following error appears:

"Type: Error Computer: Exchange Source: IMAP4SVC Category: General
EventID:1014

An error occurred calling into the Microsoft Exchange Information Store
service: the call to EcGetMessageProp failed with error 0x8004010f. "
The data is: bytes: 0000: 62 05 62 00 b.b.
words: 0000: 00620562

Either just before, during or after this error shows up, the IMAP server
works as it should for a short while.
