Symptoms
If an email sent from ServiceNow contains an attachment, and if the attachment's filename is greater than 50 characters, their attachment name is observed as
ATT*.dat
in Lotus Notes email clients.
Release
All ServiceNow releases.
Environment
Lotus notes should be used by the end users.
Cause
An email that contains an attachment filename of Report containing a very long filename with more than 60 characters.csv would be composed like following example within the email headers:
Content-Disposition: attachment;
filename*0="Report containing a very long filename with more than 60
cha"; filename*1=racters.csv
This composition conforms RFC2231, and utilized for handling long and international filenames. The issue seems to stem from Lotus Notes not supporting RFC2231: 3. Parameter Value Continuations extensions.
Resolution
You can either:
- Ask Lotus Domino/Notes administrator to upgrade the clients to IBM Notes Feature Pack 9
- Or if it's a scheduled report sending the attachment(s), change the report title to fewer characters, so an attachment with shorter names will be delivered to recipients.
