Common Outlook problems and how to fix them
A complete guide to troubleshooting Outlook issues
For most office workers, Outlook is the program they use more than any other. You practically live in it: emails, calendar, contacts, tasks and notes. When Outlook isn't working properly, your productivity stops. TRON Group specialises in Microsoft 365 and fixes Outlook problems every day for businesses across the Netherlands.
Outlook is slow: the most common causes
A slow Outlook is usually the result of a mailbox that has grown too large. Microsoft recommends keeping your mailbox under 10 GB, yet many users have mailboxes of 20 GB or more. Every email with an attachment makes your mailbox bigger and Outlook slower. The solution is to archive regularly, delete large attachments and make use of the Online Archive feature in Microsoft 365 Business.
Add-ins are another common cause of a slow Outlook. Every add-in you install slows down start-up and overall performance. Check which add-ins are active via File, Options, Add-ins, and disable any you don't use every day. Our helpdesk can sort this out for you remotely.
Fixing sync problems
When Outlook stops syncing with the server, you don't receive new emails and sent messages aren't delivered. The cause can range from an expired password to a corrupted Outlook profile. A quick first check: look at the bottom right of Outlook to see whether it says 'Connected to: Microsoft Exchange'. Does it say 'Disconnected' or 'Working Offline'? Then there's a connection problem. TRON Group offers 24/7 IT support to resolve issues like this straight away.
Professional Microsoft 365 management
The best way to prevent Outlook problems is professional management of your Microsoft 365 environment. TRON Group manages your Exchange Online configuration, keeps mailboxes optimised, monitors mail flow and steps in before problems arise. We configure automatic archiving, mailbox limits and retention policies so Outlook always keeps running smoothly.
