Hi,
We’re using Qalytpus Cloud to send a Email Report Using Office 365 SMTP.
The report is made of 10 attached files at max and in every file you find 4 tabs.
The generations of the rapport throught Qalytpus works just fine but we get a error with the Office 365 SMTP. The generation of the report Last between 1H to 1H30.
The report is supposed to be send to 125 Users but no email is sent at the end of the task.
Instead the SMTP log indicate : Smtp server[1|1/6/2026 7:07:51 AM]: XXX X.X.X **Authentication unsuccessful** [XXXXXXXXXXXXX.XXXXXXX.PROD.OUTLOOK.COM 2026-01-06T07:07:52.643Z 08DE4C90CB2534A0].
This probleme does not exist on other report. Only this one.
We also have another smaller mail report sent which use the same application as data source and this one works fine.
Does anybody know what’s causing this issue and how to solve it ?
Thanks for your reply.
