IMAP Settings for Outlook.com

Today I needed to connect to an Outlook.com email account with IMAP, however my email client couldn’t detect the correct configuration.

After some searching, the configuration details below seem to work without any issues, wether you have an Outlook.com address or a custom domain with Outlook.com.

Incoming IMAP

  • Incoming Server: imap-mail.outlook.com
  • Port: 993
  • Encryption: SSL
  • Username: you@outlook.com
  • Password: ********

Outgoing SMTP

  • Outgoing Server: smtp-mail.outlook.com
  • Port: 587
  • Encryption: TLS
  • Username: you@outlook.com
  • Password: ********

Note: It’s important to change the default SMTP port to 587 or 465, otherwise connecting to Outlooks outgoing mail server will fail.

Convert Hex, Binary to Decimal

Converting HEX to Decimal

Hex 0 1 2 3 4 5 6 7 8 9 A B C D E F
Decimal 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Convert HEX 1ADEF to decimal

HEX F = 15 15 * 160 = 15
HEX E = 14 14 * 161 = 224
HEX D = 13 13 * 162 = 3328
HEX A = 10 10 * 163 = 40960
HEX 1 = 1 1 * 164 = 65536

Therefore, HEX 1ADEF = (15 + 224 + 3328 + 40960 + 65536) = 110063

Converting Decimal to HEX

When converting decimal to hex, we simply take the remainder and match it to a HEX character.

Convert 10253 to HEX

Calculation Remainder HEX
10253/16 13 D
640/16 0 0
40/16 8 8
2/16 2 2

Therefore, decimal 10253 = HEX 280D

To get the remainder of a number without a modulo function, e.g. 374 / 8, do the following:

374 / 8 = 46.75 0.75 * 8 = 6 Remainder is 6.

Convert Decimal to Binary

Convert 278 to binary

Explanation: Assign a 0 to whole numbers, else assign 1. Continue dividing the whole number by 2.

278 / 2 = 139 0
139 / 2 = 69.5 1
69 / 2 = 34.5 1
34 / 2 = 17 0
17 / 2 = 8.5 1
8 / 2 = 4 0
4 / 2 = 2 0
2 / 2 = 1 0
1 / 2 = 0.5 1

Therefore, 278 = Binary 100010110

Convert Binary to Decimal

Convert 10111 to decimal

Index Calculation Binary
4 (2^4) * 1 = 16 1
3 (2^3) * 0 = 0 0
2 (2^2) * 1 = 4 1
1 (2^1) * 1 = 2 1
0 (2^0) * 1 = 1 1

Therefore, 10111 = (16 + 4 + 2 + 1) = 23
