    Outlook not syncing? Calendar invites disappearing? Can't send or receive email? Mount Vernon Computers specializes in diagnosing and fixing Microsoft Outlook issues across Northern Virginia.

    Microsoft Outlook ties together email, calendar, contacts, and tasks — so a single issue can cascade across your entire workflow. We understand Outlook's quirks inside and out and can get your email back on track quickly.

    Outlook Issues We Resolve

    Email send & receive error resolution

    We trace the issue to its source — server configuration, authentication failure, corrupted profile, or security software conflict.

    Outlook sync & connectivity fixes

    We diagnose whether the problem lies with your configuration, mail server, or network and restore proper synchronization.

    Calendar and contact syncing issues

    We reconcile your calendar and contact data across Outlook, your phone, and cloud accounts so everything stays in sync.

    PST and OST file repair & recovery

    Specialized repair tools to restore corrupted local data files, often saving years of email history that would otherwise be lost.

    Outlook profile rebuilds & configuration

    A clean profile rebuild with proper server settings and data migration when your existing profile is too damaged to repair.

    Microsoft 365 & Exchange account setup

    Exact server configuration, autodiscovery setup, and verification that email, calendar, contacts, and shared resources all work.

    Outlook search & indexing problems

    We rebuild the search index and configure settings to restore fast, accurate results for emails, attachments, and contacts.

    Add-in conflicts & performance issues

    We identify which third-party add-ins are causing crashes, freezes, or sluggishness and resolve the conflicts.

    Email That Just Works

    We troubleshoot everything from stubborn sync errors to corrupted data files — and explain the fix in plain language.

    "Daryl has been my go-to-guy for years. I have always found him to be very responsive and great at diagnosing problems. Recently, I had a hard drive failure on a Friday when I urgently needed my computer over the weekend. Daryl was able to get me up and running until he could install a new drive on Monday. A TRUE PROFESSIONAL! We are fortunate to have him in our neighborhood."
