You can experience sync issues in Outlook due to poor or no network connectivity. So, first check if your internet connection is stable and working properly. If the connection is slow or inconsistent, you can restart the router or contact your internet provider/IT admin for help. These syncing problems usually happen because of issues like a damaged Outlook profile, poor internet connection, or a corrupted OST file. If restarting Outlook or fixing the profile doesn’t work, converting the OST file is often the next step. EdbMails OST to PST Converter can help in these cases by recovering data from the inaccessible OST files and restoring them without data loss.
I still have it turned on on my laptop and it has not shown any issues yet. However I do not use Outlook on it as much as I do on my desktop.

For details see Identify directory synchronization errors in Microsoft 365.
Method 6: Reduce Outlook Data File (OST) Size
As you can see, there are some common themes that can cause synchronization to stop working correctly. Once you have explored the basics like internet connectivity and updated software, examining any error reports becomes critical to zeroing in on the problem.

But setup is a little complicated and it can sometimes be difficult to identify the source of problems.

Want to chat about how Microsoft 365 can benefit your business? During the scanning process, security applications, like antivirus software or Windows Firewall might lock the Outlook data file, leading to the sync issues. To check if the security application is causing the issue, you can temporarily disable the antivirus program or Firewall and then update the folders. If the issue is resolved, it indicates that your antivirus software or Firewall is interfering with Outlook. To resolve this, you can add Outlook and its related processes as exception in your security software or consider switching to a security application that is compatible with Outlook.

The client has a computer off the domain at home that his work email is tied to and he has never had any of these issues in Cache mode with that device. I’ve unchecked download shared folders when setting up a new Outlook profile. I'm running into an issue with syncing my MS account across my MS 365 Office apps. I'm signed in on my windows account and my one drive seems to be working but when I open word, excel, onenote, etc.
