I've been using Outlook for a very long time and have imported my Outlook 2011 profile when I subscribed to Office 365 for Mac with Outlook 2016 in November 2017 this autumn.
Now, I accidentally deleted ALL my personal folders under a main folder called “unnamed folders”, I think (i.e. I deleted not just single emails). The inbox is completely intact, as well as the "sent", "drafts", "trash" and "junk" folders which are all left.
I know, of course, how to get back deleted mail items, but how can I get back the deleted folders.
I had backed up about 10 days before the day when I accidentally deleted the entire pile of folders (which were sorted under a single main folder). I thought I could "restore" the version of Outlook that worked March 10 and made a "restore" of the backed up Outlook.com that I then tried to open. Then I received the message that "You will need the latest version of Outlook to open these data" so that this version could not be opened. An update of Outlook version 16.11.0 (18031100) released 2018-03-11 is then offered and I install this - everything seems to work. The program says "update successful" and I click "done." Then “a check for updates” is automatically again performed, and the program again offers the same update as I just installed. I have, of course, tried to perform the update several times sometimes after restarting the computer but with the same bleak result. I checked what version I have of Outlook 16.11 (180 311). Is this the same as the update I tried to install?
