Using Outlook for Android in business environments for email and scheduling
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I installed gmail and that has fixed the issue. Well done Microsoft another fan is now converted.
I think I'll take a look at BlueMail.
Have been very, very, VERY disappointed with the monolithic mass of bugs loosely held together by occasional bits of working code which sums up the pitiful excuse for an app which Microsoft calls Outlook for Android.
They ruined it on Windows Mobile 10 (which I ditched recently for Android - best decision ever) and then found just how garbage the Android version is. Can't even control its sync settings.
TalkTalk and Microsoft - what a team. Aka "Laurel & Hardy" or "The Goon Squad".
Utter joke.... both of them...

This appears to be confirmed as my company is running the same setup Exchange-2007 w/ android & iOS devices. According to MS in-app support the app technically does support exchange 2007 but according to the subsequent threads on this topic Ex-2007 only
runs TLS-1.0. Per the most recent response from MS, the outlook app has cutoff TLS-1.0 and now only supports TLS-1.2... so there appears to be a major discrepancy in what the app is purportedly saying it supports vs. what it is technically able to. Per the
other threads i am switching to blue mail in hopes that it will solve the issue as my imail is garbage. MS needs to respond and clarify this as apparently outlook-365 doesnt even support TLS-1.2....
I got an in-app support message last night saying:
"Our app still supports Exchange 2007 SP2. Check with your IT admin if the server is running on 2007 SP2".
Still waiting for a response after I told him that I'm running SP3 and everyone on the forums says that it's a TLS issue.
I had exactly the same response from Microsoft and reported this to talktalk, who is my email provider, not my ISP and still waiting for them to update their server.
In the meantime I am using Edison Mail.
