Fix PowerPoint Lagging and Contacting the Server Error on Mac
Question details
Users experience severe lagging during slide editing and receive a repeated 'Contacting the server for information' prompt when using PowerPoint on a Mac, especially with cloud-stored files.
- Product
- Microsoft PowerPoint
- Device & OS
- Mac
- Scenario
- Editing presentations stored on the cloud or working with large slide decks.
- Observed behavior
- The application freezes or lags significantly while continuously displaying a 'Contacting the server for information' popup.
Before proceeding, determine if the lagging issue occurs with a single specific presentation or all PowerPoint files, and verify that your Mac has a stable internet connection for syncing cloud documents.
Clear the Microsoft PowerPoint Cache on Mac
Removing corrupted cached data can resolve syncing loops and application freezing that affect multiple files.
When PowerPoint attempts to sync with cloud servers like OneDrive or SharePoint, a corrupted cache can cause the application to get stuck in a 'Contacting the server' loop. Clearing the container folder forces the app to rebuild its cache.
Ensure Microsoft PowerPoint is completely closed. Right-click its icon in the Dock and select 'Quit'.
Click on the Finder icon, then press 'Command + Shift + G' on your keyboard to open the 'Go to Folder' search bar.
Type '~/Library/Containers' into the search box and press Return.
Scroll through the list to find the 'Microsoft PowerPoint' folder. Drag this folder to the Trash.
Restart your Mac, then reopen PowerPoint to check if the lagging and server prompts have stopped.
Compress Images and Reduce File Size
If only one specific file is lagging, the presentation might be too large or contain unoptimized media.
Reinstall Microsoft PowerPoint
If clearing the cache and reducing file size do not resolve the server connection errors, a clean installation is required.

Frequently Asked Questions
Why does PowerPoint keep saying 'Contacting the server for information' on my Mac?
This prompt typically appears when PowerPoint struggles to sync changes to a cloud-stored file (like OneDrive or SharePoint) due to an unstable internet connection, server outages, or a corrupted application cache on your Mac.
Will clearing the PowerPoint cache delete my presentations?
No. Clearing the cache folder located in '~/Library/Containers' only removes temporary application settings and syncing data. Your saved presentations remain perfectly safe on your hard drive or cloud storage.
How can I stop PowerPoint from lagging when typing text?
Lagging during text entry can often be fixed by turning off the 'Check spelling as you type' feature in PowerPoint Preferences, or by reducing the overall file size through media compression.
Does offline editing prevent the 'Contacting the server' error?
Yes. If you save your presentation locally on your Mac rather than in a cloud-synced folder, PowerPoint will not attempt to ping the server, bypassing the syncing error entirely.
