Filter in Email message

What we can use for the filter in the mail message. Apart of using
“@SQL=”“urn:schemas:httpmail:subject”" like ‘%[“+in_IncidentNumber+”]%’" this.

hello @Rathanhm ,

Try this

"@SQL=""urn:schemas:httpmail:subject"" LIKE '%" + in_IncidentNumber + "%'"

Use GET Imap Mail message activity

mailMessages = mailMessages.Where(Function(mail) mail.Subject.Contains(in_IncidentNumber)).ToList()

Regards
