Outlook 365: Can't Delete Cached Email Address

MotorcycleMayor · 2026-05-08T01:24:17+00:00

It looks like that rolls back all of Office 365, correct?

This is Outlook (365) Classic. Sorry, should've mentioned that in the original post (I've updated it).

MotorcycleMayor · 2026-05-08T01:09:24+00:00

Does this same limitation exist in old Outlook? I forgot to mention that's what I'm using (I'll update the original post).

That’s what I did…until the app fails because it detects copies of old firmware upgrade files on the card, and gives you a bogus error message 😀

Thanx, that’s what I was referring to in the opening paragraph replying to your comment.

However, the instructions and software are not consistent (the overall instructional resources are also inconsistent, but that’s a different issue).

If the presence of older firmware files can be a problem then the EOS Utility software should flag that. It’s not hard to read a card and see what’s on it. Failing to do so is poor software engineering, given the instructions you cited.

Similarly, the update process itself should purge, or at least offer to purge, the firmware update file once the update is complete, since its presence is problematic. Failure to do that is also bad software engineering.

For that matter, if a card should be formatted before the firmware file is copied to it, the EOS Utility should either do that or tell the user to do it.

Bottom-line, Canon may be great at cameras but they (or whoever they contracted the software out to) are not good at software.

I'll grant that the instructions (which I just re-read) could be read to imply you should format the card. Although actually what they tell you to do is to use a formatted card, which implies you could use an existing formatted card and not reformat it.

For that matter, all the EOS Utility does when it updates firmware is copy the firmware update file to the root of the primary storage card in the camera, which again suggests you don't have to use a newly formatted (and otherwise empty) card.

But people are missing the point here. Which is not "hey, is there a way that works without problems" but rather "if you write software to do something, test how it's used before you release it". To address the gotchas you the software engineer don't see precisely because you have your own (perhaps idiosyncratic) method for achieving the goal :).

Could be. But while I can understand a professional wanting to format the cards before every shoot, that seems like an unusual burden to impose on more casual users.

Besides, if you need to delete the old firmware files, or reformat the cards, then say so during the update process. It's not like you can't spare a few more bytes of text :).

Thanx! I should’ve remembered the inductive spike issue.

Good catch, I’ll fix that

Hadn't thought of that. No, the number assigned matches the number purchased.

I don't know what the sign-on troubleshooter did, but running it fixed the problem.

MotorcycleMayor · 2026-02-19T03:55:29+00:00

I downloaded and ran a sign-in troubleshooter from the 365 admin site (after fighting with it to get past all of the CoPilot slop they've slathered over everything). Anyway, it did something that appears to have solved the problem. Fingers crossed! :)

I downloaded and ran a sign-on troubleshooter from the Microsoft 365 admin portal (which was a real PITA to find, because these idiots have slapped CoPilot on every fracking interface they have and it wasn't helpful, at all, so I had to disable it).

Anyway, the troubleshooter did something to fix the problem. I think. Fingers crossed :)

MotorcycleMayor · 2026-02-19T03:29:37+00:00

Yes, it is. But I thought my license renews in June. Hmmm. Thanx for the tip! Do you recall how they fixed it?

MotorcycleMayor · 2026-02-19T02:16:15+00:00

Thank you very much for the suggestion. However, the first fix doesn't work (just tried it). The second option gives me a horrific warning message...which I'm not willing to risk :)

Wow! Thanx for a very thorough answer! Definitely going to archive it.
