Has anyone one else had this issue? We have had 3 users now that after upgraing to 8.5.1 couldn’t send emails with crashing their client. It would suspend for ages whilst creating the NDS file. All users were over their mail quotas. The users were all still on the 6.5 mail template. It is fixed by increasing the quota and upgrading the mail template - not sure if both are required as need to act fast when users can’t send emails! It is NOT fixed by reinstalling Notes -including a complete uninstall and re-install with new desktop bookmark cache, ini etc On earlier versions of Notes, being over quota meant that mails were still sent but not saved in the sent box. We haven’t changed any policies for this. 2 of the users were on 64 bit machines one was on 32 bit. We are going to check all quotas before the rest of our upgrades and increase if we have to to avoid this potential problem
