I'm trying to install an outlook add-in and keep getting the following message. We are on O365.
"Sorry, we can't complete this operation right now. Please try again later."
Why is this happening? Thanks!

Hello, I found that you can get this error if you are trying to add an addin to a mailbox that you are accessing as a delegate. Say you open your mailbox in the browser and then click on your profile and select open another mailbox. Once the mailbox is open and you try to add an addin you will get that error message.
Make sure you are logged in as the mailbox that you want to add addins to.

Hi @Brooke DeLucia ,
You could follow the next troubleshooting tips.
It turns out our company firewall was the issue. We had to turn it off temporarily so I could install the add-in.
