Sort order finally fixed

I had given a one-star review of the Outlook app some years ago and it seems to have disappeared so I am, thus, unable to edit the review. My initial “beef” with the app was its inability to sort conversation threads properly which rendered the app unusable for me. The most recent note in a thread must appear first which is default in every other iteration of the program – desktop versions on my PCs and MacBook, the web version and as it was in WM on my very much missed Windows Nokia phones. This mistake seems to have come with Microsoft’s acquisition of Acompli in December 2014. Given its uselessness, I deleted the app from both my iPhones (work and personal) and my iPad Air and would periodically reinstall the app on one of the devices to see if the much-requested issue had been addressed. I have made do with the default iOS mail app for over nine years since. What a pleasant surprise when I reinstalled the app today to have a look. It’s fixed! I’m pretty sure I’d looked at it this past December on or about the 9-year anniversary of the Acompli purchase so the “fix” must have happened since then. It’s once again on all my mobile devices.

Microsoft Cloud Causing Sync Issues With iCloud Accounts

Currently the Microsoft Cloud Service causes sync issues with iCloud Accounts. This issue was presented on both desktop (MacOS and Windows) and mobile (iOS). When setting up the account, I discovered on the desktop app that it gives you the option to sync with Microsoft Cloud directly to iCloud this option is not available on mobile and it appears that the default is to sync to Microsoft Cloud. However, when you sync with the Microsoft Cloud Outlook fails to all of your emails from iCloud sometimes it will randomly just remove emails from Outlook. confirmed that the emails are still present in both iCloud online and Apple mail indicating that this is an issue Outlook specifically. On desktop I did select sync directly to iCloud and at this point that seems to have fixed the sync issues on the desktop version of the app. unfortunately unfortunately, as stated this option is not available on mobile and as the only fix is to use IMAP and manually set up the account and because the outgoing SSL certificate is expired use STARTTLS for the outgoing settings. Of course this means I don’t have access to the Calendar with an Outlook on mobile which is kind of disappointing but at least I got the email working until Microsoft can come up with a better solution if it is enable same or similar option as to desktop and allow a person to sync directly to iCloud.

Adequate product

In looking through other reviews, I noticed several, many, reviews that stated how bad the product was but that showed 5 star ratings. ????? It is frustrating to sit and wait several seconds to have my inbox loaded each time I select outlook on iOS. I have reviewed settings and see no correction for that. Am I downloading messages online each time data wise? When moving a message from inbox, it would be nice to have predictive folders shown as on the desktop. I have three major folders that get a lot of messages and it is a frustration to scroll all over each time. My spouse uses Apple Calendar on her phone and we have trouble she invites me on an appointment. I have tried to clear that up but can’t. I would prefer the calendar app to be separate from the email to use in separate windows. Handling and setting up groups for emails is frustrating on all platforms. As I am now retired, I have no great operational demands that Mail can’t handle so I might just go back to that. Dropping MS Office would certainly save some money. The app is not “Bad”, just adequate. Certainly, it is no joy to use but does not cause too much pain-except for that one group of about ten days of email that was lost. Never found those suckers. 🚀

Update: 9/13
Still simply adequate. I have approached my host to find out if I can move all mail from outlook to Mail.
