Question: I'm trying to create a workflow that's seems like it should be simple, but I can't seem to tick all my boxes. Essentially it's because a step can be skipped sometimes.

Item is entered - workflow starts

Step 1: Status changes to "choice A" Workflow sends an email to "person A"

Step 2: Status Change to "choice B" Workflow sends an email to "person A" (this step can be skipped as sometimes "choice B" doesn't occur on certain items. these items are identified by another choice column and i can't use content type for these items either)

Step 3: Status changes to "Choice C" Workflow pauses (usually the change to "Choice C" to "Date A" is 6 months-year) until "date A" workflow sends different email based on "Type" to "person B". Date A is also not determined until "Choice C" is reached.

end

I've played around with a few methods but my biggest problem is that sometimes step 2 gets skipped, also there are days if not weeks between each step. The list will be about 2-3000 items, so I'm hesitant to use two workflows on each item. any ideas out there? I feel like this should be simple and I'm missing something.
Thanks

Answer: 
I think the most effective way to actually sync between two sites would be using custom solutions.
Since you have passed that option, you can use **OneDrive for Business** and **Microsoft Flow** instead.

Keep both document libraries synced to OneDrive for Business. 

Then create flows for OneDrive for Business and trigger them when a file is created / modified / deleted (*properties only*) in one folder.

Please note that trigger the flow when a file is *deleted* is not yet supported.

Reference:

[Copy files from one OneDrive for Business account or folder to another.](https://asia.flow.microsoft.com/en-us/galleries/public/templates/5cb42db0cdfd4af689cdd427e0b08b34/copy-files-from-one-onedrive-for-business-account-or-folder-to-another/)
I, not sure if there has been any upgrade in 365 that solves this issue in a better way, but I´ve found something that helps somehow:
We work on plans and different levels of groups with different access to files.
The problem we had was that some teams work on files placed in a general folder/file structure but we don´t want them to access to all the info in those folders.
The solution found is:

* I´ve created a new team with it´s own Planner and members.
* Then I create a task in planner in wich I add a link to the subfolder (placed in the general structure).
This is working as the secundary team can access to the folder in the general structure but only to that folder, not to the whole structure of folders.

Hope this helps.
