MAPI Error: Could not save message when altering recurring appointment

Hi,
when altering an appointment (the startingtime in this case) and trying to send this to the participants we get an MAPI Error (could not save message):

Content:

kopano-server:

kopano-webapp:
Installiert: 3.5.0.2047+85.1

apache2:
Installiert: 2.4.25-3+deb9u6

mariadb-server:
Installiert: 10.1.37-0+deb9u1

Additional info: Could not reproduce the error. Perhaps it is only happening for this special appointment.

As this is urgent I opened a ticket @ kopano-support too. (KS-42489)

Thanks!

support told me that it might only be a problem with this one recurring appointment. So, we left it that way. If it happens again, I will send the EML File (of the appointment-altering-mail) to the support.
