Important email completely disappeared when sending
I am using office 365. I spend a lot of time writing this email. It included one other email as an attachment. When I sent it it simply disappeared. The only sign that it had ever existed is the following failure message: Your message did not reach some or all of the intended recipients. Subject: Re: Mr Elliot Gingold - quote for recliner - Urgent Sent: 28/05/2026 5:18 PM The following recipient(s) cannot be reached: S****** 28/05/2026 5:26 PM ****** on 28/05/2026 5:26 PM E******x on 28/05/2026 5:26 PM This message could not be sent. Try sending the message again later, or contact your network administrator. __________________________________________________ Diagnostic information for administrators: __________________________________________________ Error is [0x80040305-0x00000000-0x00000000].

Submit-Message failed: message id(1), failure enum(29), HResult(0x80040305), EC(0). *(Names of recipients hidden) I cannot try to send it again as it has completely disappeared. No trace of it in Drafts, Outbox, Sent Items, Deleted Items, or anywhere else! The only mistake on my part I can find is that I am now using New Outlook!! Is there any way I can get my email back again? Or is the time I spent on witing this email gone up in smoke?? Elliot
How do I find the account linked to an Office Home & Student 2013 key?
Hello everyone, Microsoft's after-sales service redirected me here because they no longer provide updates for this type of product, nor even security support. I have two Microsoft accounts. However, when I try to reconnect my key to one of them, it tells me the key is already linked to another Microsoft account. But which one?! How can I find that account or regain ownership of my Office key ? Thanks for your help.
New Outlook autocompletes an address that is no longer in use and I can't seem to delete it
Topic says it all, really. Client of mine has a new company and when I type the start of his name Outlook autocompletes for his old company even though it is no longer in my address book and his contact is updated with new information. I seem to recall there used to be an "x" that would let me delete incorrect autocompletes, but I can't find anything and Copilot has no useful suggestions. The autocomplete comes up in both the web version of Outlook--I basically never use this--on my PC which I primarily use, and IOS.
How to filter to include blanks without selecting blanks.....
Good Morning All, I have a spreadsheet on Excel Online version that people fill in for requesting PPE and it has drop down boxes so they can select what they need. The people filling it in are not the most knowledgeable with computers never mind Excel just FYI for context. When the spreadsheet gets filtered eg to show only the requests for Bob, it shows the items for Bob and then the row underneath is row 532 which is outside my data and therefore the drop down boxes do not show so when someone comes to fill it in they can't select what they want to order and just end up free typing which defeats the object and means things can get missed. I want to be able to filter the spreadsheet in any column EG Bob so it shows the items for Bob and then the next row is the next 'available' row which in this example would be row 23 but also people are filling this in daily so row 23 is not set. Tomorrow it will have more data in and the next 'available' row could be row 30 so obviously tomorrow I would like to be able to filter to Bob, see all of Bobs items and then the next row showing is row 30. This is a test doc: https://1drv.ms/x/c/15153d41767146da/IQDVK5iPAiw-SoUyrf9ciYdwAb76zwpiF-IAtr6ISry1KwQ?e=v4vo3C Hope that makes sense and hopefully I am not asking for the impossible! Many Thanks,
Outlook Cached Mode Repeatedly Re-syncs Mailbox After Restart (Starts Again Around 3.99 GB)
Hi everyone, I’m experiencing a strange Outlook Cached Exchange Mode issue with a Microsoft 365 mailbox after a recent Windows rebuild and wanted to see if anyone has seen similar behavior. Environment: Microsoft 365 mailbox (Exchange Online) Outlook for Microsoft 365 Version 2605 Build 16.0.20026.20076 64-bit Windows 11 25H2 Fresh OS rebuild performed twice New Outlook profile created Office completely reinstalled OST recreated multiple times Issue: When Cached Exchange Mode is enabled, Outlook starts downloading/synchronizing mail normally, and the OST file continues to grow correctly. However, after every reboot or Outlook restart, Outlook again shows “Downloading…” starting from around 3.99 GB. Important observations: Online Mode works perfectly OUTLOOK.EXE closes properly after exit OST file is NOT deleted and continues growing Sync slider changes (1 month, 1 year, all mail) make no difference Disabling Outlook indexing did not help New Outlook profile did not help Reinstalling Office did not help Problem only started after OS rebuild Before rebuild, same mailbox worked normally in Cached Mode No pending office or windows update. It does not appear to actually re-download the mailbox from scratch because the OST size keeps increasing, but Outlook repeatedly processes/downloads from around the same 3.99 GB point after restart. Has anyone seen: Cached Mode replaying synchronization repeatedly after restart? Similar behavior on recent Current Channel builds? Security/EDR products interfering with OST synchronization state? Any known regressions with Outlook Version 2605 Build 16.0.20026.20076? Any suggestions or similar experiences would be appreciated.Tenant-to-Tenant Migration with Orchestrator – Technical Overview (Microsoft 365 | Preview)
Tenant-to-tenant migration with Orchestrator in Microsoft 365 introduces a native, API-driven, and highly validated approach for cross-tenant migrations. It is designed for enterprise scenarios where sequencing, dependencies, and governance are critical. Note: This capability is currently in preview. Features and behavior may change before GA. Architecture and execution model Migration is executed through batches (jobs) managed via Microsoft Graph (Beta) User-level execution: one user failing validation does not block others in the same batch Mandatory Standalone Validation before migration submission Date-driven cutover using completeAfterDateTime Supported workloads (actual scope) Exchange Online Microsoft Teams ODSP (OneDrive for Business) Important clarification on SharePoint Orchestrator does not migrate shared SharePoint content such as Team sites, Channel sites, or collaboration sites. The ODSP workload covers personal user data (OneDrive) only. SharePoint team/workload sites remain out of scope and require separate tooling or processes. Critical prerequisites Identity Mapping (CTIM) is mandatory and must remain stable during migration Target users must not have Exchange mailboxes or OneDrive sites provisioned before migration Licenses must be assigned only after Identity Mapping (ExchangeGuid stamping) Migration apps and service principals (Teams, Meetings, CTMS) must be correctly provisioned Organization Relationships and Migration Endpoints must be in place Exchange autoforwarding must be enabled for Meetings migration Validation and lifecycle Standalone Validation acts as a full “what-if” check Key states include: Cancellation or user removal is possible only before cutover Post-migration cleanup After completion, tenants must be returned to a non-migration state: Remove Identity Mapping data Remove Organization Relationships Remove Migration Endpoints Revoke migration app permissions and service principals Decide whether to retain or remove MailUsers in the source tenant Skipping cleanup leaves the tenant in an exception state. When this approach fits Mergers and acquisitions Divestitures and tenant splits Regulated environments requiring strict control Scenarios where dependency-aware sequencing matters more than speed Technical conclusion Orchestrator is not a one-click solution. It delivers native orchestration, deep validation, and predictable execution when Identity Mapping, licensing order, and scope boundaries are fully understood. For experienced administrators and architects, it represents a major step forward in tenant-to-tenant migrations within Microsoft 365, even while still in preview.
Formulas Not Calculating in Workbook
Hello, I have a very large workbook with many formulas across different sheets. I currently have this workbook set to manual calculations only. And it is saved in a Sharepoint Directory with autosave enabled. When the source data for this workbook is updated. None of the formulas are updating when 1. The Calculate Now button is pressed. 2. The workbook is set back to automatic calculation. 3. When the work book is manually saved and closed. I have noticed another issue. When I go to File > Options. The Options dialogue never appears. I am wondering if anyone else have experienced this issue, and if so have been able to successfully troubleshoot the problem?Table Design -How to see which table styles adopted
I have only recently discovered table design / table styles in word and is trying to adopt using it just like Styles in my work. But I realize that I am facing a problem. For word style, i can usually see which style is adopted by clicking in the existing paragraph and check with style is highlighted in the style gallery. This does not seem to work for table styles. I previously set a custom table style and then apply it to an existing table in the document. When I click on the table, I do not see "custom" being highlighted in the table styles gallery. Is there also no way to name table styles like word styles? It gets really confusing to search only by visual shape/colors in the gallery. I really want to remove some of the table styles from the gallery to avoid users from trying to use them.
EXCEL SE HA QUEDADO SIN RECURSOS
Hola buenas tardes. Desde hace unos días, cada vez que quiero introducir cualquier cambio en una hoja de Excel, me aparece el mensaje: "Excel se ha quedado sin recursos al intentar calcular una o varias fórmulas. Como resultado, no pueden evaluarse estas fórmulas. Para obtener más información, haga clic en Ayuda." El problema es que no sé cómo encontrar la fórmula o fórmulas que pueden tener algún error para corregirlas, y por tanto no sé cómo solucionar el problema. Gracias de antemano y reciban un cordial saludo.
