Flow not Triggering (Sharepoint Modified)

I have a flow that is connected to a large, heavily used Sharepoint O365 List. Up until late last week (I believe it was 5/25/17 around 2:30pm-ish), it worked like a dream. 100% success. 


The flow is designed to pick up modified items, do a check against a "Status" field, and based on that, either send an email or skip. Due to the fact that I'm statusing, and on each status change I save the item, it kicks off multiple flows per item. I have 3 statuses, New, In Progress, and Completed. When it gets moved to Completed, it sends the emails.


Like I said, up until last Thursday, it worked like a dream. It would trigger on both in progress and completed, and run the whole flow on completed. A+. Well, silly ol' me introduced a second, smaller workflow on the same list to test something, as opposed to messing with my perfect child. Thats when the problems started. 


I noticed my new flow only triggered about 2/3rds of the time. It would detect the "In Progress" save, but then never detect the "Completed" save. It wasnt erroring out, flows just was NOT triggering. Unfortunately, the trend has spread to my heavily used email workflow. 


To get a sample size, I scrolled through my email to see what my sent box looked like. In 2 days and a few hours this morning, there have been a total of 337 items "Completed". Of those 337, ONLY 215 have triggered on the modify containing the "Completed". Thats a 64% success rate folks. Thats TERRIBLE


Here is what I have done to troubleshoot so far:

  1. Deleted the second, smaller flow
  2. Turned off, and then turned back on the flow in question
  3. Reset the "Connection" user, just incase something funky was going on there. 


No, the list name hasnt changed. Nothing significant has changed to the list. I havent modified the flow (outside of the connection user stuff). It simply went from perfect to garbage. Has anyone else experianced this, or can a mod/admin tell me a solution? I've done everything I can think of short of deleting the flow and starting from scratch, but I dont want to go through all that trouble and it still not work. It took forever to write, because I have several versions of HTML emails going on...

I have a similar problem, for now I will patch to 2 lists rather than one.

Having a similar issue, except mine doesn't work on certain file types?  It works fine with xlsx/docx/txt, but anything else its not picking up?

@MCCLabelFlow to clarify the flow triggers when xlsx/docx/text are created, but not other file types?


To investigate, we will need:

- The flow that ran or didn't run

- The timestamp + timezone in which a file was created but the flow did not trigger.

Eastern Standard Time.  These are files that are being copied from another directory.  We have another flow that this is working in, picking up files copied?



Hello Dblyth,

   I am still having issue. Flow is not trigerring sometime and sometime when i save the item 3 times (Since its modified it should trigger that flow but it only executes it twice not for the third instance.)


How can we solve these issues, this is very frustating. What Microsoft is selling is really not working.

I have submitted a support ticket to MS as there is definitely something going on witht he platform today. None of my Flows load.

Changes in quick succession can be batched, there is no guarantee that every single edit of an item will result in a distinct flow run. Sharepoint does this specifically to AVOID running multiple times when users change fields in succession. Also, the recurrence interval calculated based on your plans (premium vs O365/Free) can come into play, where Sharepoint will pick up changes a few minutes apart to the same item). 


@npokhrel123 I have an old Flow id of yours, but without any info about the exact times at which you made changes, Sharepoint & Flow cannot investigate anything. Please share timestamp (including timezone) when you made changes. 


@abpmr_entarc can you please share details about what you are seeing? That sounds entirely different than what this thread is about (SharePoint triggers not triggering for some changes).

Fair enough. Thank you for the heads-up.

This is a very aggravating issue. There must be a set of cases that apply for a flow to not work. We are using a very basic flow - when a file is added, send an email to a specific list of people. Half the time (or less) it works and half nothing ever shows in the logs. So whether it is file name restrictions, file type restrictions, frequency of the flow (even though we pay for a full flow license), or whatever the case might be, this system is far from working as advertised. It would be great if a list of all the conditional factors was available or just a confirmation from MS that this system doesn't work and shouldn't be relied on.

@MCCLabelFlow The Flow you shared with me above is using the filesystem trigger, correct?


Not to discount the bug, but it would explain why I've been unable to reproduce this with the the SharePoint trigger (which is what this thread is generally about). I can keep investigating your issue about the FS trigger not processing certain file types. 


@JD7 100% agree, and I have asked the SharePoint Product Managers to document the expected behaviors on their triggers -- how quickly they can be expected to fire, how/when changes may be batched together into a single flow run, etc.
