did the damage happen inside or since the move outside?

It happened inside.

I have a sago and a ponytail that were inside. No damage but they were just vaguely sad looking. I moved them outside and it seemed to shock them a little at first - big change here in incredibly humid/scorching hot coastal Georgia. My sago moved first and got sunburned :( so I learned with penny the ponytail and kept them both in the dappled shade of the yucca tree. They're thriving now. Perhaps bringing her home was a big environmental change that made her freak out and drop leaves? I also find that mine need to dry wayyy out before watering, like halfway down. Your majesty may have needed more heat and humidity?

Forgot to add that palms grow like wildfire here in our part of Georgia and they withstand drought, intensely hot sun and humidity that can peel the paint off things (literally) so she will pull through if you show her some kind neglect I think!

Majesty palm is never easy indoor . I never met anyone who successfully keep one indoor

Make sure it's in full fun and it gets lots of water outside. It is not good for indoors. I would find a better suited plant for indoors come fall.

How much lights your majesty palm gets? Delightfulldoe?

It is beside a south/east window. I’d say it get pretty good indirect light for the majority of the day. It also gets some very light dappled sun in the morning and again in the late afternoon from distant west and east windows.

My my sister also has one, she keeps her in front of a north window and it seems happy there as well. Growth isn’t quite as fast as mine but it is still putting out new fronds. I don’t have any pictures of hers though sorry.
