My organisation is using Office365.
I just created a security group. I called it Developer Security Group. I also have a Sharepoint site. All the developers were added to this exchange site. I removed them all from the exchange site and added the security group instead.
In the security group, everyone is added as a member. The security group is added as a member to the site as well.
I believe I have done everything correctly, but nobody has access anymore. Is there an update cycle until it takes effect? How long does it take? Or did I do something wrong?
Edit: It started working. Took somewhere in the range of 1-3 hours.
