in our SharePoint-Online tenant, external sharing isn't possible anymore from one day to another.
No one changed something in the admin settings and the settings should be set correctly:
The enduser sharing dialogue looks like this since a few days:
External sharing isn't disabled on sharePoint site collection level, it's not possible on all sharePoint site collections: team sites and communication sites.
Has someone experienced something similar? Was there an update from microsoft who could have something to do with this?
Thank you for your help!
