Wondering if there is a limit to size of attachments with approvals - I have been trying to do this with eight 3MB attachments and am having the same issue. I have a business need to either:
1) be able to compress images/attachments when they are originally attached in PowerApps (doesn't currently work for Andriod phones)
OR
2) be able to send large attachments in an approval and complete the flow
Currently, with the large attachments, the approver is able to receive the email for approval and access the attachments in Power Automate through a link and approve BUT the approval is stuck in the flow and will not move forward.
Yup. The limit to the size of attachments for approvals is 5MB. I just found this out today actually. Limit to size of send to email (v2) is 3MB. These limits are kind of ridiculous.
We are currently working on an official announcement / documentation that got delayed by the Holidays. Regarding the attachments limits I can give insight to why as I did everything I could to allow the maximum size based on existing limitations in other systems:
In order to maximize the attachment size limit it's more complicated than one simple limit. It's actually three limits:
Approvals backend service
Combinedattachmentsize (sum of allattachmentsizes unencoded) is 50MB.
We set thislimit.
Common Data Service
Individualattachmentsizelimitdefaults to 5MB
A CDS admin can change this by going into CDS -> Email Configuration settings -> Set file sizelimitforattachments
The internal emailing service we use:
Combinedattachmentsize is 5MB
If thislimitis exceeded thenattachments do not show up in theapprovalemails and instead an "attachments are too big" message shows up with a link to see them in theApprovalcenter.
Everyone is most likely hitting the Common Data Service limit of 5MB which they should contact their admin to increase. Common Data Service allows the limit to be set to a maximum of ~132MB for an individual attachment.
We are now working on the functionality to attach files to Approval requests.
