attachment missing when file size is > 5mb for start and wait for approval attachment array

[Vonne_L]

Hi

I have been trying to attach files to "start and wait for approval".

the approval process works & files are being attached to approval email when the file size is less than 5 MB.

When the total file size exceeds 5mb, then the approval email will be sent but without the attachments.

I am wondering what is the max file size & how can i resolve this?

hi @Vonne_L do you try with get file metadata? I remember that there is a field that contains the size.

 hi 

@ChristianAbata , I did. The only time that i will receive attachment in the approval email is when the attachment is less than 5 MB.

I did not receive any error message when the attachment is > 5mb, it is just missing.

Hi @Vonne_L ,

Please check this error message, if the size of attachments >5mb, this error will appear.

The default limit size is 5MB, please contact your admin to make sure the limit is properly configured.

Besides, please check this link and see if it helps:

Hi Barry  @v-bacao-msft,

I did not received any error message. The approval message is being sent out but without the attachment.

That's why i am not sure what is the issue here.

Thanks

Hi @Vonne_L ,

If you configure Flow as follows and attach the file>5MB, you would reproduce this error:

@v-bacao-msft 

I have reproduced the flow as below with attachments of 6MB & the flow runs successfully but without the attachmentS in the email. what is the maximum limit for the file size that we could attach?

attachments missing

I also tested the flow with one single file which is more than 5mb. The flow also run successfully without the error message but the attachment is missing from the approval email.

Hi @Vonne_L ,

Thank you for your reply!

The default maximum file size is 5mb. If the size of the attached attachment exceeds 5mb, the attachment may be removed or the error shown in my screenshot will appear directly.

And if the attachment is removed, there will be a corresponding reminder in the email.

Please consider increasing the limit of the size of the attachment according to the method mentioned in the links provided in my previous post.

Please take a try.

Best Regards,

thanks Barry. I will request out IT department to look at this.

@v-bacao-msft ,If i am using "send an email (v2)", does this restriction of 5 mb still applies?

[v-bacao-msft]

Hi @Vonne_L ,

I have made a test on my side using Send an email action.

We could attach the file which size is greater than 5mb.

Please take a try.

Hi,

I still missing attachment  in approval attachment array, I has setting my email like below

and setting in power platform 15mb file attachment. 

in email V2 template attachment > 5MB not problem, just problem missing in email approval flow.

please help for this issue..

Hi @Vonne_L  and @ThreeAngle 

Did anyone find a solution for this?

At first I also got the error: "CdsApiAttachmentSizeLimitExceeded", in my flow, but after increasing the file size in CDS, I no longer get the error in my flow.

However, when the Approval flow email is sent, attachments >5MB is missing.

I tested with the action "Send an email (V2)", and for this attachments >5MB is attached, but when using "Start and wait for an approval", then attachments >5MB are missing.

Has this been resolved for anyone? I've increased the default email settings in the power platform settings to 16mbs and still the attachment is getting removed.

Hi there is no workaround as of now.. its a Microsoft feature. Read the last item of the document: Power Automate Approval Attachment Limitations and Restrictions (microsoft.com)

Your users can still read the attachments via power automate approval centre by clicking on the link on the email.

Well thanks to this I was able to piece things together and figure out my struggles.

To summarize it all, with the default 5MB set, I get a flow error.  I had the limit increased to 20MB and no longer got a flow error until the attachment exceeded  20MB.  But, the approval email still will not send an attachment over 5MB.  It will, though, include a link to get it.  So why is there a limit in the first place?  Really, increasing the limit just raises the bar for getting a flow error or not.
