We are an SMB with an on prem exchange 2016, but using AD conenct to sync our AD passwords with our microsoft accounts, just be able to easily login to teams.
We are planning to remain using on-prem exchange (no exchange online). However yesterday I went through the HCW wizard for full hybrid mode, but only to enable calendar functions in teams.
Our office 365 accounts do not hold email-accounts (only using Office 365 'apps').
Now last night our incoming mails stopped. We can still send mails, and also internal mail is working. But external mails are not arriving, and I don't know where to look. Incoming mail connector looks default.
Can anyone please help?
