Deploying Exchange 2016 into an Exchange 2013 Organisation with MAPI over HTTPS Enabled

This issue may be encountered when migrating to Exchange 2016 from Exchange 2013 when MAPI over HTTPS is enabled.  The default Exchange 2013 MAPI over HTTPS authentication settings set IIS and Internal Authentication methods as Negotiate and External as null.  This is shown below:


The Default Exchange 2016 MAPI over HTTPS authentication settings are configured as "Ntlm, OAuth and Negotiate"


Proxying MAPI over HTTPS connections between Exchange 2016 and Exchange 2013 requires NTLM be enabled.  The default Exchange 2013 MAPI over HTTPS authentication settings will cause Outlook connectivity issues when both Exchange 2016 and Exchange 2013 are in the same Active Directory site.

The error which is generated by the Exchange Remote Connectivity Analyzer in this configuration is as follows:

  1. WOW!! This is the most wonderful thing i have ever experienced. I visited a forum here on the internet on the 17 APRIL 2016, and i saw a marvelous testimony of Tracie Aldana from United States on the forum about the good works DR OSEMU. I never believed it, because have never heard anything about such miracle before. No body would have been able to convince me about it not until DR OSEMU did a marvelous work for me that restored my marriage of 4 years by getting back my divorced wife just as i read on the internet. I was truly shocked when my wife knelt down pleading for forgiveness to accept her back. I am really short of words to use to show my appreciation to DR OSEMU. For his a God sent to me and my entire family for divine restoration of marriage. Here is his email if you need any kind of help.

  3. BEST SPELL CASTER ONLINE TO GET YOUR EX LOVER BACK,contact Dr.Unity of Unityspelltemple@gmail.com


    I've been married to my husband for 13yrs.A very big problem occurred in my Marriage seven months ago, between me and my husband. so terrible that he took the case to court for a divorce. he said that he never wanted to stay with me again,and that he didn't love me anymore.So he packed out of the house and made me and my children passed through severe pain. I tried all my possible means to get him back,after much begging,but all to no avail.and he confirmed it that he has made his decision,and he never wanted to see me again. So on one evening,as i was coming back from work,i met an old friend of mine who asked of my husband .So i explained every thing to him,so he told me that the only way i can get my husband back,is to visit a spell caster,because it has really worked for him too.So i never believed in spell,but i had no other choice,than to follow his advice. Then he gave me the email address of the spell caster whom he visited.[ Unityspelltemple@gmail.com ]. So the next morning,i sent a mail to the address he gave to me,and the spell caster assured me that i will get my husband back the next day. What an amazing statement!! I never believed,so he spoke with me, and told me everything that i need to do. Then the next morning, So surprisingly, my husband who didn't call me for the past 7 months, gave me a call to inform me that he was coming back. So Amazing!! So that was how he came back that same day,with lots of love and joy,and he apologized for his mistake,and for the pain he caused me and my children. Then from that day,our relationship was now stronger than how it were before,by the help of a spell caster.

  4. Getting ex back after a breakup. Am Maria 21 from England,my boyfriend of a year just broke up with me and am 30 weeks pregnant.I have cried my self to sleep most of the nights and don’t seem to concentrate during lectures sometimes I stay awake almost all night thinking about him and start to cry all over again.Because of this I end up not having energy for my next day’s classes ,my attendance has dropped and am always in uni and on time.Generally he is a very nice guy ,he ended it because he said we were arguing a lot and not getting along.He is right we’ve been arguing during the pregnancy a lot .After the break up I kept ringing him and telling him I will change.I am in love with this guy and he is the best guy I have ever been with.I’m still hurt and in disbelief when he said he didn’t have any romantic feelings towards me anymore that hurt me faster than a lethal syringe.He texts me now and then mainly to check up on how am doing with the pregnancy,he is supportive with it but it’s not fair on me, him texting me as I just want to grieve the pain and not have any stress due to the pregnancy.i was really upset and i needed help, so i searched for help online and I came across a website that suggested that Dr Unity can help solve marital problems, restore broken relationships and so on. So, I felt I should give him a try. I contacted him and he told me what to do and i did it then he did a spell for me. 28 hours later, my bf came to me and apologized for the wrongs he did and promise never to do it again. Ever since then, everything has returned back to normal. I and my bf are living together happily again.. All thanks to Dr Unity . If you need a spell caster that can cast a spell that truly works, I suggest you contact him. He will not disappoint you.This is his E-mail: Unityspelltemple@gmail.com or Add him up on Whats-app: +2348071622464,you can also visit his website:http://unityspelltemple.yolasite.com .
