Outlook & Cloud Sync Troubleshooting

My desktop and laptop have both become sluggish and unstable. Outlook is now crashing several times a day and I suspect the 30,000-message mailbox is the chief culprit. I want to bring that mailbox back under control by archiving older threads, deleting anything truly unnecessary, and then re-optimising Outlook so it launches and searches quickly again.

While we are at it, both machines have hit their disk-space limits. Google Drive and OneDrive are syncing far more files than I actually need offline, and the growing local cache is eating the last gigabytes on each device. I’d like you to review the sync configuration for both platforms at the same time, ensure only the essential folders stay local, and confirm that SharePoint libraries linked through OneDrive are also syncing properly (they have been falling out of date).

Deliverables I need from you:
• A leaner, crash-free Outlook profile on both computers, with a clear outline of what was archived, what was deleted, and how the data file size improved.
• Updated Google Drive and OneDrive settings that reclaim meaningful disk space yet keep my critical files instantly available.
• Verified SharePoint sync so the same versions appear on desktop, laptop, and the web.
• A short, plain-English report of the steps you took and any maintenance tips I should follow.

Remote assistance is fine as long as the session is secure. Let me know your proposed plan and an estimated timeline, and we can get started right away.
