Outlook for Mac facilitates offline working in an Exchange environment. Synchronization between the server and client application is done so that whenever there is any modification in the Server-side or client-side, the change gets updated on the other side. Sometimes, this synchronization process gets affected partially or fully. Due to this, mailboxes are not updated on the server-side as well as on the client-side.

Prominent Reasons Behind this Synchronization Issue

Many Outlook for Mac users face this issue, and so we need to realize the causes behind it. We have stated them here:

• Offline Mode: Your Outlook for Mac is in Offline Mode
• Failed to Connect: You failed to connect Outlook for Mac with the Exchange Server
• Cache Issue: Your Outlook Cache is corrupted
• Settings: Settings are not accurately configured

Now, as you have got the main reasons behind the issue, we will provide you some ways to get out of this issue.

1. Check Offline Mode
   It is the most basic check that you can perform before pursuing any other method. Go to the Outlook menu and check if the Work Offline option is selected or not. If selected, unselect it and check if the synchronization is better now.
   
2. Rebuild the Outlook for Mac File
   To fix this issue, you should perform the troubleshooting as explained here.
   Firstly, close all the Outlook for Mac related processes currently running on the system. Take a backup of the Identities folder of Outlook for Mac in C drive. Then click on Outlook application with Alt key on hold to start the Microsoft Database Utility app. Here, select the identity which you want to recreate and click the Rebuild option to create it. Wait until the process gets completed.
3. Clear Cache in Outlook
   This method works when any specific folder is not synchronizing, but the rest of the Exchange folders are synchronizing with the Outlook. Here is the fix.
   First, ensure that there is a connection between Outlook for Mac and Exchange Server. Right-click on the respective Exchange folder which is not synchronizing and click on the Properties option. Now, switch to the General tab and click on the option Empty Cache. Next, check if the folder is synchronized and new items are received in it.
4. Confirm Exchange Connectivity
   The issue can be due to error in connection of Outlook with the correct Exchange Server. You should check it once to confirm if this is the issue. Follow this process:

   Go to Tools > Accounts in your Outlook for Mac and check over the Exchange Account. If there is an orange indicator against the added Exchange account, then it means there is some issue with it. You can try disconnecting it and re-configuring it. Try connecting it with Outlook on the web and check the status of Exchange Server now. If everything is fine, connect the desired server again.

The above methods are easy and can solve the synchronization issue between Outlook for Mac and Exchange Server. You can give these solutions a try and get rid of that unwanted situation quickly.
