How to force Office 365 to sync?
Method 9: Resync the Mail Folders
Microsoft 365 provides essential productivity services that allow users to collaborate across devices and locations. This includes enabling the synchronization of email, calendar appointments, contacts, tasks, and notes seamlessly between different platforms. However, sometimes sync issues can occur, which lead to changes not syncing properly or data not staying up to date between connected services and apps. In this guide, we will provide you with comprehensive troubleshooting instructions to identify and resolve the most common Microsoft 365 synchronization problems that may arise.

I’ve tried the Microsoft office uninstall tool provided by Microsoft (which deletes more items then just control panel uninstall). Now, restart Outlook and check if Outlook synchronization is working. I’m at wits end and Microsoft stopped helping me because they feel the problem is on our end. However, I cannot find any reason why his account would do this only on our domain nothing is blocking our connection to Office 365. However once I joined this computer back to the domain and let it sit for a few days it was also working fine.
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. You’ll also receive a mail (to the alternate email and to your admin email) from Microsoft 365 that indicates your tenant has encountered directory synchronization errors.

Method 2: Check if the Work Offline Mode is Disabled
However, with one particular client no matter what changes are made these sync issue still occur. Here is the strange part I tried to remove the computer from the domain and have Outlook run from a local account for a few days. I’ve been in contact with Microsoft they had me migrate his account\data to another server this did not fix it.

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.
- We have a Hybrid environment with a lot of our accounts being created on premise in Active Directory and syncing to O365 and exchange.
- However, I cannot find any reason why his account would do this only on our domain nothing is blocking our connection to Office 365.
- Once you have explored the basics like internet connectivity and updated software, examining any error reports becomes critical to zeroing in on the problem.
- If restarting Outlook or fixing the profile doesn’t work, converting the OST file is often the next step.
- I’ve tried to set cache mode from 1 year all the way down to a few days.
We have resources to help you identify potential issues and fix them. After rebuilding the OST file, it’s important to check for any missing mailbox data. If you find any missing items in the new OST file, you can recover them from the backup OST file using Stellar Converter for OST. This professional OST to PST converter tool can extract data from the backup OST file and convert it into PST file, which you can easily import into Outlook. You can easily search for the missing items, select them, and save them in PST and other file formats, such as MSG, EML, RTF, HTML and PDF.

Once the client started using Outlook again after some time has passed the issue had come back. I ran the PSTscan tool to check for anomalies on the OST file (which it found and repaired but the issue still occurs). Below FixTechGuide Office 365 support are the steps I’ve taken to try to resolve this issue.
