A problem with MS Exchange or why outlook does not want to synchronize? 0X80040115 error

Question

Hi everyone,

today 2. april 2024 around lunchtime, we had a problem with two users connecting their outlook to the exchange server.

In the event logo of Windows there is a recurring message about the loss and restoration of the connection with the MS Exchange server, but in principle the synchronization does not work at all.

Restarting and repairing the office package didn't help. Even deleting the account and adding it again didn't help.

Any halp?

Hi @Tomáš Rovňák

Could you provide the screenshot of the error message to us?

According to your description, it seems you have error 0x80040115 code when you connect to Exchange Server. In this way, we recommend you check the following suggestions:

1)You should first check if your network is stable and not encountering any issues while connecting to the mailbox server. One way to verify this is to log in to your email using a web browser or webmail.

2)Ensure that the drive where OST is stored (usually C: drive) has more than 10% of the overall drive size space available.

3)Run the following command in the Command Prompt window to flush the DNS cache:

ipconfig /flushdns
