My Office 365 mailbox is no longer syncing across devices and I need a specialist to get it working smoothly again. I have already created the account, but something in the configuration is clearly off, as new messages appear on the web yet never reach Outlook on my laptop and phone. Here is what I expect from you: • Diagnose the root cause of the sync failure (cache corruption, OST/PST issues, autodiscover, etc.) • Apply the appropriate fix in the Office 365 admin portal or local Outlook profile—whichever the issue dictates • Test and confirm that mail now sends, receives, and syncs in real-time on at least two devices • Provide a short note explaining the steps you took so I can reference it later You may use whichever tools you prefer—Outlook desktop settings, Microsoft 365 Admin Center, PowerShell commands—so long as the problem is fully resolved. Once everything updates instantly on all devices, the job is done.

This is a fixed-price small-fix job (not hourly) — £20–250 is a reasonable range; for a straightforward Outlook/O365 sync diagnosis + fix across 2 devices, but we'd price it at £350 flat, deliverable within 24-48 hrs including the write-up. SolutionzHere handles O365 admin/Outlook troubleshooting routinely (autodiscover, OST rebuilds, profile resets) — quick turnaround, no back-and-forth needed. Question: are both devices (laptop + phone) on the same Microsoft 365 tenant/admin account you control, or is IT access restricted?

Hi, I can troubleshoot the Microsoft 365 mailbox by tracing whether the issue originates from Exchange Online, Outlook profile/autodiscover configuration, cached credentials, or OST synchronization. I’ll correct the relevant Admin Center or local Outlook settings, use PowerShell where useful, then verify sending, receiving, and real-time synchronization across the laptop and phone before documenting the fix. A few questions: * Does Outlook on the laptop show any specific sync or connection error? * Is the affected mailbox working normally through Outlook on the web? * Which Outlook version and mobile platform are being used on the affected devices?

Hello I understand your Office 365 mailbox isn’t syncing across devices despite new messages showing on the web. This usually points to issues like corrupted OST files, misconfigured Autodiscover settings, or profile glitches. Here’s how I’d fix it: I’ll start by diagnosing the root cause using Outlook logs and Exchange diagnostics. If it’s a local profile or cache problem, I’ll rebuild or reset it. If it’s server-side, I’ll check and adjust settings in the Microsoft 365 Admin Center or run PowerShell commands to correct sync policies. After applying fixes, I’ll test mail flow on your laptop and phone to confirm real-time syncing. Finally, I’ll provide a clear summary of the steps taken for your reference. Have you noticed any error messages in Outlook or specific device behaviors during sync attempts? Best regards, AbdulHamid
