Hello,

I am creating flow to create a case when we receive an email in shared mailbox using custom flow. I want to trigger a flow based on filter expression because I do not want unnecessary triggers for flows. I want to trigger a specific flow so I have added condition to check subject of email like To check "cancel" or "order" keyword of email subject.

On create or update of email...

Filter Expression = contains(subject,'%cancel%'). IF email subject contains "cancel" keyword then trigger a flow.

The above condition is not working. It's not triggering a flow. I have used xrmtoolbox to copy expression but still it's not working for me as per this video :

Could you please help me on this.

Thanks

Pradip

Hi Pradip how are you?

Pradip, did you try to use only contains(subject, 'cancel') ?

I mean, without the % character.

Please let me know if this information helped on your question.

I did a small test on my organization and the filter expression is ok. Maybe you have to remove the filtering attributes.

If the importsequencenumber is not changed the flow will not run.

My sample:

Hi Rodrigo,

I have removed filtering attributes and now it's working for me. Thank you for this.

But I found that it is a case sensitive. For Example, I have check for contains(subject, 'cancel') and if I send email with subject "Cancel" then it won't work. Is their any workaround to achieve this.?

Thanks

Hi Pradip sorry for the delay to answer.

You can use tolower expression like my sample below.

contains(tolower(subject), 'cancel')

Please let me know if this information helped on your question.

Hi Rodrigo,

Thank you very much for this. This is working like a charm.!!

Yesterday, I tried this "toLower" function but it didn't work for me because of syntax - "toLower". "toLower" is not working in filter expression with "When a record is created, updated or deleted". Even in Microsoft doc and other community blogs the syntax is "ToLower" - docs.microsoft.com/.../workflow-definition-language-functions-reference which is not working with filter expression.

"tolower" is working fine with filter expression. Syntaxt are as below :

Previously we tried the below "or" operator and it was working fine for me but it's case sensitive.

contains(subject,'CANCEL') or contains(subject,'Cancel') or contains(subject,'cancel')

Save my lots of time. Thank you again Rodrigo.

Thanks

Pradip
