How to fix error message "The operation cannot be performed because the object has been deleted?" when sending an email?

When sending an email, I often get the error message, "The operation cannot be performed because the object has been deleted", despite me not doing anything different compared to when it does send. Sometimes it fixes itself, but other times it takes days to resolve. Does anyone know a way to fix this? Thank you.

    I also would like to add that at least half of our organization is affected and every day we add more people to this problem. All the 3 current issues we are facing, affect the classic Outlook, there's definitely something wrong there and Microsoft is not giving us any solution.

    I do want to add that this error has been persistent for half of our org of 70+ employees for the last 6 weeks. We've been running Repairs on the ost files which has helped slightly, but this comes up again shortly thereafter for some of our users. Simply recreating dozens of profiles is not a sustainable fix. I'm really surprised there's not an Advisory alert in the admin center about this.

    We've also started experiencing these errors over the last few weeks.

    We're using Outlook with Office 365. I notice that a "Sync Issue" and "Local Failure" item is also generated. The Synchronization Log entry shows:

    16:43:45                                 [8004010F-501-8004010F-320] 16:43:45                                 The client operation failed. 16:43:45                                 Microsoft Exchange Information Store 16:43:45                                 For more information on this failure, click the URL below: 16:43:45                                 https://www.microsoft.com/support/prodredirect/outlook2000_us.asp?err=8004010f-501-8004010f-320

    Can't find anything that looks currently relevant to this error - most Google results are when using Outlook with IMAP which is not the case here.

    We have been experiencing the same issues for the last few weeks as well - I’ve found a workaround to save the message in the drafts folder and then open it up and send it but that’s not a fun workaround to explain to all users.

    With the increase of this are we assuming it’s a bug from MS that’s in these later Outlook releases? We’re on 2406 build 17726.20160
