a bit wierd problem i run in to.
i have a customer, they do have a invoice program that can automatically use the local email client om the computer to create email, attach a pdf and send them.
This does work with one of the customers email accounts, but when i change the standard account in outlook i just get an error message, [0x80070005-0x0004dc-0x000524].
Both accounts are Office 365, the one working is Business Standard and the one not working is a Echange online license.
The Outlook client in this case is Outlook 2016.
The Error code suggest it is due to permissions on the account, the thing is there is no problem at all sending emails from this account direct from outlook. it is just when sending via the invoice program.
Anny one have any idea what the problem can be?
