Are you using a VPN connection when this happens?
If yes, follow the steps from this article:
Thanks, i followed your link and set it up as split tunneled, still dosent explain why it happens on some PC's and not on others
In that case, i think that the best option for you is to contact Bitdefender Consumer Support, as the support engineers could take a deeper look at the issue on the other PCs, so do the steps below.
First, take screenshot(s) of the issue,
create a log file on your Windows devices using Bitdefender Support Tool, by following these steps:
create a connectivity log file, by following these steps:
create a log file on your Windows devices using BDsysLog, by following these steps:
Next, contact Bitdefender Consumer Support by e-mail:
with short description of the issue.
After that, you will get an automated reply by the Bitdefender Customer Care Team, with your ticket number.
Now, in reply to that automated reply, you can send the screenshot(s) you already took and the log files you already created in the first step.
Since you are all done, just wait for the support engineers to investigate your issue and find a solution to fix the issue.
Remember that the screenshot(s) and the log files will help a lot to the support engineers for better and faster investigation on your issue and finding a solution.
NOTE: If any of the log file is larger than 25MB, you can upload the log file here:
After the upload is done, you will get a notification with the file's URL and then you can share the file's URL with the Bitdefender Consumer Support.
Taken from a previous similar thread, this is what worked for one of our members:
In the event the VPN is disconnected and Outlook is still blocked, you can temporarily disable the security modules one by one and check if the emails are unlocked after each deactivation. This procedure should help identify the module that blocks the app. Refer to the below article for detailed steps and don't forget to reactivate your defenses once the troubleshooting process is completed:
I would check the Online Threat Prevention module first, turn it off/on and see what happens and then add an exception like Adrian Tony did and check if everything works afterwards.
