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??

Been trying to find a solution to this with no luck as yet. When I receive an attachment such as a PDF file, JPG, etc., clicking the file opens it as a preview in Outlook. Similarly, when I click on the down or menu arrow to see options for opening, preview is the first option. How do I set it so that when I click on the file it opens in the default app for my system? Also, can I remove preview from the options in the dropdown? I'm running Windows 11 build 26200.8246 and new Outlook version 1.2026.420.300.SolvedSP_UserApr 29, 2026Copper Contributor351Views0likes3CommentsOutlook Classic "hangs" if I want to open attachments
I have outlook classic on 3 PCs. Within the last month, I have noticed that it takes an incredibly long time to open attached files. Outlook "hangs" for up to 1 minute, and then the file opens. The same thing happens if I copy a file from one email to another. Does anyone have an idea what is causing this. It is quite annoyingSolvedTorzenApr 16, 2026Copper Contributor72Views0likes2CommentsConditional Formatting to New Outlook Calendar
Please bring Conditional Formatting to the New Outlook Calendar. This is a feature we have in Classic Outlook and something I use regularly to help maintain my organization. I've programmed it to color Work Time separate from Travel Time and various meeting categories so that visually I know a lot about the appointment just by the color.SolvedRyanW-Apr 16, 2026Copper Contributor304Views1like2CommentsOutlook login - temporary problem with recovery service
Hi, Sorry if this is the wrong place in advance, I have had my hotmail.com account probably since circa 1998 and it has everything on there. It seems someone has tried to login so many times that suspicious activity has been detected, I have tried many ways to recover it. I have 2FA Switched on but when I try password recovery to get it to text my mobile it states that service is unavailable :-( It will email to my 1st alternate email account however it then asks to use the second one to which was an old work account that I have no access to :-( Any ideas? do I just wait until it unblocks my phone number? I have the 25 digit recovery key but I get the below error. All help welcome as I really need my account back!SolvednewshawlaneApr 14, 2026Copper Contributor246Views0likes3CommentsRoom Mailbox Time Zone change
Hello there, has anybody experienced what the consequences of correcting the time zone configuration of a room mailbox when its already fully booked with appointments (especially re-occuring ones)? The appointments are all booked from Central European Time Zone and the Room Mailbox is in Reykjavik Time Zone. What will happen with the existing serial meetings? Our fear is that after correcting the time zone of the room mailbox to CET, then it will +-2 hours move the appointments.

Hi all, Yesterday and today I have seen several people across at least two separate organizations have their Teams Add-In in Outlook crash and get disabled. Upon initial reviews from our team, we have found the following: Visual C++ runtime The .NET Runtime logs show an unhandled exception in: Microsoft.Teams.MeetingAddin.Scheduler.OneAuthUtils.Startup This occurs while the Microsoft Teams Meeting Add-in for Outlook is initializing. The crash happens right after the Teams add-in loads Curious is anyone else is seeing the same issue and if any fixes have been found.SolvedkpcostelloMar 26, 2026Copper Contributor762Views0likes2Comments
