Outlook 365 - Contacts - Mobile phone numbers - leading 0 missing

A peculiar thing happened yesterday. I was in my car yesterday, waiting for a phone call from my wife to pick her up from some appointment. It should have been just 15 minutes or so, but after 45 minutes I received an email to pick her up. She was angry assuming that I had switched off the mobile, which was not the case. Obviously I should go through all her nagging until we were home. Note, she has no knowledge of smartphones: she clicks on a button and things should work.

At home I verified and indeed: it did not work.

I was puzzled as things worked fine until recently and I have not changed anything.

Noticed that, on the smartphone, under Phone > Recently previous phone numbers were displayed with a leading country code.
i.e. +31 6 [phone number]
whereas yesterdays number was displayed as: 6 [phone number], missing country code.

In Outlook I then discovered that all leading '0' (mobile phone numbers) were missing and long phone numbers (abroad ) showed up like 4,53560E+19 as the leading '00' were gone!

I then manually added all the leading zero's.

Now, THE big question is: how come that all of a sudden those leading zeros were missing from the mobile phone numbers in Outlook? The non-mobile phone numbers were still okay.

Windows 10 x64, Office 365 subscription and Outlook (v2301 16026.20146) on Exchange basis.

The iPhone should already be set up with the proper country code. If you are showing exponential formatting in Windows, something is wrong with your windows install. If you are using Google Voice to make and receive calls, again it is a issue on Windows not the phone.

Thanks. Frankly I would not what to 'correct'. All used to work well, until very recently. After manually adding leading 0 at all mobile phone numbers in Outlook and a re-sync Outlook > Gmail things were corrected. Puzzled though why those leading zeroes in Outlook were removed in the first place... What could have caused that...

If you put a zero before the actual phone number, in the U.S. you would be dialing the operator. You only need to enter +(Country Code) (actual phone number). In your case it would be +AA AA AA AA (A representing the numeric digit). Telephone numbers in Denmark - Wikipedia

To make things work, in Outlook (at least with me...) it should look like this:



I have not been able to figure out why, all of a sudden, all (all) leading '0' of the mobile phone numbers were gone. For sure it wasn't me. The home phone numbers were not touched though.

Anyway, as said, added those leading '0's, everything is alright now.
Nonetheless a curious problem....

You never place a Leading Zero in a phone number. It can take it that you are wishing to dial the telephone operator id here in the U.S. CRM software is coded to strip that leading Zero for phone numbers regardless.

Denis that is why I stated that here in the U.S. it will strip the zero. Yes other countries may use a 0 or 00, but it all comes down to how software and mobile devices are programmed through code to recognize that information and can cause issues. The only other reason that the OP shows exponential numbers in their CRM software is that the database info got messed up and was not recognizing it as a phone number.
