New User - error message sending emails

** Never mind, suddenly started to work. **


I have just purchased and installed Bitdefender Antivirus Plus.

I use Microsoft Outlook 365.

Right after I installed Bitdefender I tried to send/receive in Outlook. I can receive emails (so far) but I have two emails stuck in the Outbox. One has an attachment and the other does not.

I get the following error message:

I have zero clue what's happening but I assume it's Bitdefender because my email worked fine before I installed it.

Any ideas?
