Power Automate: Join Action
Joins an array into a single string with the delimiter you choose. An empty array returns an empty string.
The Microsoft Power Platform is a family of low-code tools for building apps, automating work, and creating websites without writing everything from scratch, and this hub ties my coverage together. My biggest section by far is Power Automate, where I share hundreds of tutorials, reference pages, and answers about building cloud flows, wiring up connectors, and automating the repetitive tasks that eat your day. I also cover Power Pages, the tool for building secure, data-driven websites on top of Dataverse, so you can turn your business data into a real web experience. Across both areas my goal stays the same, to give you practical, hands-on guidance that gets you to a working result instead of leaving you lost in the documentation. Each sub-area goes deep on its own part of the platform.

Returns the current timestamp minus a number of time units. Always counts back from now in UTC.
Returns the full message behind a message ID: body, sender, mentions, and reactions. The body arrives as HTML.
Splits a string or array into pieces of a fixed size. The last chunk is often shorter.

A connection stores credentials; a connection reference is a named pointer to one, living inside a solution.
Convert a solution flow from a direct connection to a connection reference and unlock the new designer.
Converts a date string into an ISO 8601 timestamp using a locale and optional format. Locale comes second.
Writes multiple values into a SharePoint lookup column by mapping each tag to its list item ID.
Returns an array of emails from a mailbox folder. Filter fields only scan the first 250 emails.
Converts a timestamp between two time zones, daylight saving included. Output drops the zone marker.
Which account really runs each action, and why a flow that works for you returns 403 for everyone else.
