Have multiple (atleast 3) exchange calendars. 
Mark on of them for offline usage.
Go offline. Select the folder not marked for offline usage and 
try to create an appointment. In the appointment creation dialog,
select another exchange calendar folder, which is also not marked for 
offline usage.

looks like exchange storage process goes into some infinite loop and evolution hangs.

same behavior is seen, when evlution is invoked in offline mode.

I see 
cal = 0x844b968
cal = 0x844b938
cal = 0x844b908
cal = 0x844b8d8
cal = 0x844b8a8
cal = 0x844b878
cal = 0x844b848
cal = 0x844b818
cal = 0x844b7e8
cal = 0x84534c8
cal = 0x8453498
cal = 0x8453468
cal = 0x8453438
cal = 0x8453408
cal = 0x84533d8
cal = 0x84533a8 ...
