MS Outlook Exchange Issues (Mails not coming through, disappearing etc)

[Ockie]

Hello ladies and gents. Any of you having issues with MS Outlook Exchange? Friday, a bunch of my emails just vanished out of my Inbox. Logged it with our Support and they checked and could see the mails was delivered. The ones I replied to was in my sent items, but the orginal ones just up and left my inbox somehow. We did a password reset on my Microsoft account. Now I am having issues receiving emails from one of our providers for example, and he says others in his company also having issues. He sent me the mails he sent to my work email this morning to my gmail and it came through. I then forward those to my work email and nothing .... it just does not come through to my Outlook. No bounceback reports or errors or anything.

Anyone else experiencing strange issues like this?

First issue: You are probably using the new outlook, with 'Conversations' enabled. This can make mail trails "disappear". Disable this setting under View. You should get your mails back.

(Note I am using old outlook, it will look a bit different in 'new' Outlook.)

Second issue: Get your IT team to ensure your domains have SPF, DMARC and DKIM records. Yahoo/Gmail just recently enforced these settings. And this can cause mails to fail to deliver. Alternatively, you need to check your quarantine area, as the emails might be flagged as spam prior to even getting delivered to your inbox.

Howzit. Thank you for the reply. Nope, I am using the old Outlook. Tried the new look a while ago and hated it so reverted back. And no, my "Conversations" setting is not enabled, so it is not that either.

Most "disappearing mails" are the result of accidental deletion (so have to undelete them under Folder > Recover Deleted Items) or being dragged into another folder, in my years of experience.

He gets no returned e-mail errors?

@Ockie, disable all your rules and have a look at your junk folder.

Could be a rule that has gone rouge or even a malicious one.

OK, our IT guy found it. It was quarantined on the server. We dont know why. Those email domains have now been whitelisted. Got blasted by emails all at once. /sigh

As for the emails disappearing out of my inbox, they have now made a return also.

Have noticed that mail service providers worldwide have increased email domain security requirements.

Mail-sending domains now have to abide by the requirements for SPF, DKIM and DMARC, otherwise the mail tends to end up being rejected or classified as spam.

You can also throw in BIMI and ARC as well if you feel like it, although the former seems to be a money-making scheme at this point in time.
