    Office 365

    My university has just migrated my mailbox from MS Exchange to MS Office 365. One of the FAQs says that IMAP will no longer be possible, 'as Microsoft will no longer be supporting IMAP from October'. Does this mean the end of my long-running use of Pegasus? A real downer if so.

    I have a large PMail folder stored on my PC rather than the server with many years' worth of non-academic emails. Any suggestions about how best to keep these emails usable? Thanks.

    Maybe DavMail is the tool you need, pretty easy to set up.

    Re: Office 365

    David,

      Do you have a link to FAQ you are looking at regarding IMAP please. Any hint that POP3 still viable?  I have just uninstalled Office 365 as it does nothing for me. Back to LibreOffice.

    Re: Office 365

    Hello Martin. Thanks for your interest. I agree about Office 365 but have no choice.

    The FAQs are on our StaffNet and almost certainly not publicly available. There is no mention of POP3. For Linux users (of whom I am not one) they say this: 'Colleagues that currently use IMAP (Internet Message Access Protocol) should note that they will no longer be able to use this for University email, as Microsoft will no longer be supporting IMAP from October. Instead, you will be able to use Evolution, a modern authentication email client which does not require the legacy protocol and therefore is much more secure and longer lasting. This is currently available and the appropriate package for your machine can be downloaded from the internet.'

    To continue to access University email on my Android phone, I've had to give the IT department permission to wipe my phone, turn off its camera, and goodness knows what else, if they see fit. They are terrified of University emails getting outside their closed network, disclosing some confidential info about someone, and making them liable to a claim under the GDPR. But I have been using my univ email for 40 years, long before GMail, and I had and still have a lot of non-university-related mails coming in. I never used full Outlook on Exchange or now on Office 365 except to make backups (now in theory no longer accessible to me!), and mainly used Pegasus, sometimes the Outlook app in a browser for its excellent search), and my phone. Since this morning it's just Outlook in a browser or the Android mail app, as I won't use the infuriatingly locked-down copy of Outlook 2016 on my managed PC.

    As for the local mail folder on my C: drive, I can still see that in Pegasus in offline mode but can't add to it, so I'm looking for a way to migrate its contents to my GMail account.

    best

    David

    Re: Office 365

    I can only repeat myself, David, take a look at DavMail, it works as a "proxy" for accessing Office 365 via Pegasus Mail through IMAP, POP3 and SMTP, here's its self description:

    Ever wanted to get rid of Outlook ? DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP exchange gateway allowing users to use any mail/calendar client (e.g. Thunderbird with Lightning or Apple iCal) with an Exchange server, even from the internet or behind a firewall through Outlook Web Access. DavMail now includes an LDAP gateway to Exchange global address book and user personal contacts to allow recipient address completion in mail compose window and full calendar support with attendees free/busy display.

    I've been using it in a similar way until a couple of weeks ago.

    Re: Office 365

    Thanks, Michael. I did briefly use DavMail on a previous PC. Have downloaded it now but am having difficulty setting it up properly.

    Take a look at the settings I use, you need to figure out the proper https://... address yourself, of course. It's usually the same one you use for web access. Port numbers are more or less arbitrary. In Pegasus Mail you need to configure your POP/SMTP/IMAP ports using these numbers. The server host name is always localhost. Username and password are the ones you're using for web access as well. It's important to disable all SSL/TLS options since Pegasus Mail is only talking to DavMail - which uses proper security settings when connecting to the remote server as required.

    Re: Office 365

    I suggest you read the article about demise of IMAP at Microsoft: https://office365itpros.com/2020/03/03/basic-authentication-exchange-online-so-bad/

    There seems to be some dispute about the actual date for IMAP shutdown. Very recent Google articles are putting strike-through on the actual date, as Microsoft is taking the user feedback in consideration. The only good news appears to be that OWA will continue to provide a browser based client.

    Re: Office 365

    Clarification:   the basic authentication in IMAP is still ending on October 20, 2020. So allowing users to login to MsExchange using IMAP (SMTP, and POP) will need to be updated or replaced to support OAuth2.  The issue for external users is that there are many implementations of POP, IMAP and SMTP that are fully functional as-is, that will need to be updated to allow access to Microsoft services such as MsExchange.  For work from home this will mean the PCs, laptops, tablets etc must me updated and functional to be useful. With COVID active this will demand a large community of external users prepare ahead of time.

    Thanks again, Michael. Tried this. No go. I'm pretty sure the IT dept have blocked EWS access.

    Re: Office 365

    David,

       I have been struggling with trying to get an understanding of OAuth2 etc, and from my 30,000 foot view, it seems like Microsoft (and others) are trying to implement end-to-end encryption and validation. It seems that every external user who wants to connect with MsExchange has to pre-register with a MS Authorization service.  And then a key is supplied by Microsoft, which must be used for any communication with MsExchange.   Deja Vu.....   This seems like the setup used by Private/Public key encryption (Eg PGP or GPG), and once the keys (aka certificates) are established, all can continue. But if the user changes email address or other personal details, then a new Key/Certificate must be generated. This is by way of revocation of the existing key and creation of a new key.  

    I also just came across a Microsoft article that defines the way MS GRAPH is going to use OAuth2. Boy, if you want a good sleeping pill, try reading up about that !! 

    It seems to me that if Microsoft want to communicate with its user community this would mean multiple millions of keys need to be generated and maintained. 

    Thank you for food for thought, and I hope this mess will get delayed until a half-decent document can be created by Microsoft to explain to regular users what they are intending .

    Regards

         Martin
