shared mailbox (exchange online) permissions change log

Copper Contributor

If amendments were made to a shared mailbox, e.g. new user granted access to the mailbox, existing user removed from access to the mailbox, is that activity logged anywhere in the 365 platform?

@ChristianBergstrom ok thanks, some of the descriptions in that article seem to suggest such actions (permissions amendments) should be captured. Is there a default timeframe for how far back the logs go? Or is it more based upon the number actions to a set threshold?
