I am new to Office 365, I set up a one month trial of E3 and connected my private domain to it. Mailflow is fine on my two Windows 10 PCs and Samsung Galaxy 9 and iphone (v13.3.1).

However I cannot get email to work on my ipads, they immediately get quarantined. If I use EAC to select my mailbox and then view my mobile devices I see the ipads in quarantined state. If I select them and choose allow, they go briefly into a pending state and then go back to quarantine.

The ipads are quite old, being v2 and v3 and have been reset to factory defaults and updated to 9.3.5 which is the latest available for these devices. I tried to download Outlook for IOS but I get an error stating it is not available for this ipad.

Are these devices just too old to connect to Exchange? When I set up the built-in mail client I get all the checkboxes ticked.

Thanks in advance.

I wonder if you could help us with the phone configuration in Dubai.

We have a 3CX phone system in the Uk
We’ve just rented some space in a service office in Dubai
And have arranged  for Port 5060 (inbound, UDP) for SIP communications and
Port 9000-10999 (inbound, UDP) for RTP (Audio) communications to be opened on their firewall and linked to the IP addresses of the phones in the office.

We are told that the public ip is which can be used to access the services (I don’t under this part)
However the phone are showing a SIP error and not currently working.

We’ve only two full days left in the Dubai office and I am reaching the edge of my understanding.

Would you be able to assist ?

Kind Regards

Get Outlook for iOS

My iPhone just recently go hit by a spam or virus, don't know which.  But started noticing the message "iphone virus protection expired" in my calendar and no way of deleting the event.  Eventually I did get to delete it.  And that's where my great experts come in.  In early morning I did noticed that my iPhone calendar popped up a "suscribe" message and I clicked it assuming it was part of the work I was doing, but now I know it wasn't.  Just some time back I I start seeing in my calendar "iphone virus protection expired" with no hope of deleting.

I googled the problem and found that by deleting the created account in "Password & Accounts", that would resolved (and it seem it did, no more event).  Prior deleting the account I noticed a long line starting with then a long random numbers etc.

So a couple questions:
  • How is it that just by clicking on Subscribe, the the "virus or spam" had access to my Password & Accounts in iPhone 11 ios13.3?
  • By deleting the account, am I done? Is it solved? Anything else to do?
  • What is
Probably an obvious question, but considering the differences between phones and tablets for javascript games..

... Is the proper way to do browser + device games' object locations in fractions of device height and width? And size game objects as ratios also? What must I do concerning strategies for phone/tablet+browser? AND device rotation accommodations?
How does Javascript detect phone / tablet/ browser?

I don't have a tablet. Which is the best to get for game dev? many ... iPad, Surface . . . not necessary, any?
Let's consider a word game like Wordscapes. The main interface is the circular  object to select letters for a word-answer. Is that just 1/4 of width distance from border and x% width for the circle diameter?
How different is it, really, on phone/tablet? What is the proper solution for all this?

I have two iPad devices that are running the IOS 12.X code and the users forgot the password for these two devices. I would like to reset these devices to factory defaults in order to get these two devices working again.

I tried to use Itunes to do a factory reset but the device fields are disabled.
The user has two email accounts, which I'll call - personal,  and
The company account is hosted by Google.

Just a few days ago, for unknown reasons, all email from their personal account started being sent from the company account instead.

They called Apple, which tried a few things, and then said it was a Google problem.

I had them delete all their email accounts from their iPhone, power off the iPhone, and then set up their personal account on the iPhone again.  
They can receive email sent to their personal account, but sent email is still being sent from the company account.

I didn't yet have them "Reset All Settings" on the iPhone.

What might have caused this, and how might it be corrected?

We got some new ipads but they have IOS 13.3 and I need to downgrade them to IOS version 12.2
Hi Experts

Could you point an overall (basic) guideline on how to implement an App (Android/ Ios - maybe IONIC ) that must to persist data at an AWS NoSQL database (MongoDB) ?

Thanks in advance.

I have a group conversation and would like to add someone to this conversation. How can I do this?
I have a node.js express web application I’d like to covert to a native app for iOS and Android so that I can use the smartphone Bluetooth interface to connect to peripheral devices (Raspberry Pi and/or Arduino). I’d like to develop one app for both iOS and Android and am proficient with JavaScript so am leaning towards React Native, although I have no experience with React. I’m also considering Swift and Flutter. I’d like to develop in my IDE of choice, VS Code, if possible.
This project is foremost for learning so a long learning curve is not an issue. Main considerations are leveraging my web application dev experience and learning new tech that will last.
Any input is welcome!
I got a new Lenovo laptop running Windows 10 and iTunes 12.  I am running Outlook from Office 365, and have iTunes set to use Outlook for syncing Contacts and Calendar.  But when I synced my iPhone 6 to iTunes through the computer it wiped out all my existing Calendar and Contact data, although Outlook on the computer has all the information.  I tried using the "Replace Contacts and Calendar" option, but that didn't accomplish anything.  Please help.

repaired MacBook has same ID and password and is logged in and recovered all the photos that were on the iPhone. however there are numerous folders and files sitting in iCloud that haven’t transferred to the MacBook. what can I do to get these on the MacBook and get both devices for certain talking to the same iCloud account which they half way seem to be now. iOS is latest release as is MacOS.
Hello, I have an Ipad Air that will not do anything I have left it on the charger for a day, also I tried to do a hard reset holding the home and on/off button with no luck. Is there any way I can get the data off the drive my customer really needs some pics and data off the system?
We have a custom phone app built in Native code to run on iOS and Android. This app allows customers to scan a QR code on machinery and access manuals and other data. How do we offer a license or some key to unlock the app after download? This is very much a case where other people (potentially competitors) should not be allowed access to the data just by downloading and installing an app. Thanks!

I have an iPad running iOS 13.1 that I need to get back to iOS 12.4. I know that Apple stopped signing iOS 12.4 so a traditional downgrade is not an option. Would doing a clean install of iOS 12.4 work?  I do own CopyTrans software which I have all the data I need backed up on my iMac. At this point, is there any way to get iOS 12.4 back onto this iPad?  Thank you very much for your help.
I am using iPhone 6 Plus, I tried to export Whatsapp chat with Media of 1 contact and send it via the Mail app.

The attachment was 48MB, the Mail app provided two options for me to choose as the attachment was too big.
Option 1: Use Mail Drop
Option 2: Trying sending attachment.

I selected Option 2, but I never receive any error, never receive the email, and I even cannot find it in the Outbox.

Where is the email then?

Old iPad running ios 10.  Where/how do i find Youtube file i downloaded?

Everything went ok apart from 1 question I have:

upgrade to same IOS - done
set priority to 1 to be member - done
write erase - done
delete vlan.dat done
backup run config of stack

stacked the 3rd switch correctly
powered on added switch
current joined stack not powered down
switch came up as stack - sh switch shows as member

now not sure if this is normal but none of the new switch interfaces had any VLAN assigned in their config.
I did a int range and assigned them all -so no big problem. However I was expecting them to be picked up and configured from the master. So is what I have experienced normal??

I have a new iPhone 11. it doesn't show the percentage of the battery usage. I had that percentage shown in my previous iphone.

Thank you very much,
We have a few newer iPhones and when it sends sends a picture out to an email. It shows the pictures out embedded as opposed to attached. Now If I look phone to phone it shows it as an attachment. I am not sure if this is being caused from the phone side or the email side. We are running exchange with office 365 pro plus
I recently upgraded from aniPhone 7 plus to an 11 Pro MAx. All my data was on iCloud which transferred to the new phone, or so I thought. When I look at the 8000 or so photos and videos, some appear to be on my new phone and open up immediately, some I get a message that the phone needs to download the file first before it opens.

I want to make sure that all my data is residing locally on my new iPhone. How do I accomplish this?
I'm looking for an iOS texting app that offers end-to-end encryption but that doesn't display to other users that I'm using or have installed the app.

Signal appears to be a very well-designed app, but as soon as I download and launch it, I see the names of all other Signal users that are in my iOS contacts. Needless to say, they can also see that I use the app, and that's what I wish to avoid.

I'm looking for a secure iOS texting app — I don't need it for calls or anything else — that I and one other person can use without alerting any of our contacts to the fact that we're using the app.

Thanks for any suggestions!

I use Google Calendar as my calendar, which is then synced with Apple's default Calendar app.

My daily events and meetings change several times throughout the day, however Apple Calendar seems to be constantly out of sync with my Google Calendar. It seems like it syncs once an hour so it's quite useless on m my Apple Watch.

Does anyone know if it is possible to get Apple Calendar to sync more frequently with Google Calendar. I can't seem to find any settings.

Thanks in advance for your help.
Outlook for iOS and Android issues with on-premise Exchange 2016 CU13.  The Server Exchange 2016 is installed on is a Server 2012 R2.

I have a client that I cannot get the Outlook app to connect to any mailbox.  iPhones and iPads say unable to log in and Android devices say same thing but also (408).

OWA is working, Outlook clients are working, auto discover test passes both on-site and off-site.  I have checked and tried everything but cannot figure out what is blocking the Outlook app.

If I use an Apple or Android devices native email client it works BUT I need the Outlook App specifically - that is the only other option and it should work.

As a test I did try the Outlook app with two of my other clients that have same setup and it worked but I cannot figure out what is blocking the Outlook App for this client.

Any help would be greatly appreciated!  I've been trying to figure this out for a few days.
