Microsoft Office 365 users have been complaining for a long time that this software compendium runs very slow on their Mac platforms. The problem usually occurs after some time of the program’s usage. The users have reported that the offline versions i.e. Word, Excel and PowerPoint, all run way too slow on their systems.

I have Microsoft Office 365 ProPlus and I've been having issues using Excel recently. I'm not trying to do anything fancy, literally just colour text, make it bold, do basic sums on it. But it can take around 5-8 seconds just to make a cell's text red for instance. I have huge amounts of available ram and a very fast desktop pc.

Here is a 1-stop solution to help you boost up your Mac by removing any duplicates in it and as an effect, Office 365 will start performing much better than before.

Clone Files Checker adheres to the standard security procedures of the industry

There are multiple solutions available on the web to tackle this issue. In the following lines, we’re reproducing a selection of the best ones.

Turn Off Spell Checker

If the slowdown issues occurs while you use Office 365 online then the best way to resolve it is by turning off Spell Checker, as the Spell Checker extension in Office 365 uses additional resources that lead to Mac slowing down. Turn it off and check whether this makes a difference. You can even disable it in the offline version by going to File | Options | Proofing. Now simply deselect all options which you deem to be unsuitable.

Conflicting Startup Items

Another reason the MS Office installation runs slow on Mac is because of the conflicts caused by various startup items. Solve this issue by moving the Startup items folder altogether.

You have to search for the folder named Startup items. This folder is only accessible if there is a software which is somehow utilizing the computer’s startup resources.

Go to Safe Mode and open the Library folder.
Now copy the Startup items folder to a destination of your choice.
Restart Mac

Network Delays in an Active Directory Service Environment

Delays in opening a document can also occur when the computer is connected to a domain through Active Directory. Make sure that routers are updated and also examine their speed. Try to disconnect the routers and retry opening the document to see if this helps.

Corrupt Service Discovery Protocol Configurations

The Service Delivery Protocols form an integral part of Office 365, and their corruption can lead to grave issues (including slowdowns). To see if the protocols are causing this issue, follow these steps:

Head over to the Go menu and click Utilities.
Start the Directory Access program.
Click the Services tab.
Enter login credentials of an administrator.
Clear any checkboxes that are selected.
Click Apply and then relock the Directory Access program.
Close it.
Now relaunch Office and re-test it to check if the document opens with a faster speed.

Insufficient Permissions

Files open very slow in the Office 365 app due to the lack of adequate privileges provided by the Mac. This can be fixed by using the Repair Disk Permissions feature.

Open the Go menu and click Utilities.
Now start the Disk Utility program.
Select the primary hard disk of your Mac and select First Aid.
Finally, click on Repair Disk Permissions.

Disable Mac OS X Firewall

Office 365 verifies its registration on every startup. For this reason, it connects to the Internet. The Mac OS X firewall can block Office from verifying the registration. In that case, it will stop responding for a few minutes and then close itself. Simply disable the firewall by:

Click Sharing | Stop.
Close the System Preference window.
Finally, reboot MS Office.

Turn Off Automatic Graphics Switching

Users have reported that they were able to solve the problem by switching-off Automatic Graphics Switching.

Close all the Office applications.
Head over to Menu.
Click System Preferences | Energy Saver.
Now uncheck Automatic Graphics Switching.

Erase Duplicate Fonts

Sometimes, duplicate fonts can also cause Office 365 to run very slow on the computer. Resolve this issue to get rid of this sluggishness in Office 365 on Mac.

Open the Font Book application.
Under Edit, select Look for Enabled Duplicates.
Delete any duplicates that are detected.

Disable third-party apps

You can also make Office 365 perform a lot faster on Mac by disabling any third-party apps that control the system.

Click on Menu | System Preferences.
Now select Security & Privacy.
Now click the Privacy tab.
Select Accessibility from the menu on the left menu.
Disable it.

Reinstall Office 365

As a golden rule of thumb, if nothing else works you can always try out uninstalling and then performing a clean installation of the problematic software program under question. Hence, do the same for Office 365 and check the results.

This article will definitely make matters a lot easier for you in the quest to uninstall and re-install Office 365.

Symptoms

When you try to open a file from a network location in one of the Microsoft Office programs such as PowerPoint 2003 , Excel 2003, Publisher 2003 or a later version of them, the Office program may run very slowly or may appear to stop responding (hang).

Cause

This behavior may occur if the connection to the network location is lost during the time that your Office program is opening the file.

Workaround

Important

This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.

Right-click EnableShellDataCaching, and then click Modify.
In the Value data box, type 1, and then click OK.

More information

This situation may occur after you click Open in the Open dialog box (on the File menu, click Open) to open a file from a network location (for example, a network server). During the process of opening the file, you lose your network connection or the network location that contains the file that you are trying to open goes down. During the process of opening the file, your Office program tries to add the file name and the path information of the file that you are trying to open to the Windows recent file list. Because the network location (path) does not now exist, the Office program may run slowly and may appear to stop responding (hang).
