I've been transitioning from a local spool file to leaving mail on an imap server. In the process, I'm running into the same issue as reported here:
https://lists.gnu.org/archive/html/viewmail-info/2013-04/msg00008.html Exchange 2010 is erroring on storing the "filed" flag from VM. Based on the thread from last April, this is purportedly Exchange not adhering to the imap standard. This surfaces as a "vm-imap-send-command: writing to process: invalid argment, IMAP over SSL" and I can't get new mail or run vm-imap-synchronize. The workaround I've employed is to expunge filed messages prior to getting new mail. How could this be fixed client side, in VM? What should VM do in this situation? Does anyone have alternative workarounds for Exchange 2010? Is there a way to clear the filed flag from messages? thanks, Kyle
