Change from IMAP to Exchange

demcgovern — Thu, 23 Apr 2026 21:15:02 GMT

I been unable to sync my calendar & contacts between Outlook desktop and my Android phone. I am using Microsoft Office 365 on Windows 11 and a Galaxy Z Flip7 FE android phone. My email provider is Gmail with the setup IMAP/SMTP.

Apparently, IMAP is the problem, and I need to be on Exchange. How can I switch to Exchange without losing my files, contacts and calendar items?

Thanks Don

I have two email accounts on Outlook (for Mac). But I cannot access, nor can I even find, the primary one. I’ve asked AI several times but failed to get an adequate step-by-step method to locate it. Thank you.

Issues with outlook and teams on android

powerboat — Wed, 22 Apr 2026 07:56:52 GMT

I'm not sure why, but since yesterday both Teams and Outlook have quit working. I have an S25 Ultra. I attempted to clear data and cache and do a fresh install. Outlook just hangs on a black screen with the notification "optimizing database," and Teams just indefinitely loads.

I can't check my personal email or my work email and can't keep track of my work chats on Teams.

Cannot reset account password

ratataekans — Mon, 20 Apr 2026 20:55:59 GMT

I created an email address for RSVP purposes. I do not remember the password, and cannot find what I wrote it down on, and have never sent an email from it so I cannot provide enough information to recover the account.

I have phoned support and all the bot does is refer me to the website reset which does not work. How can I talk to a real person or recover this account?

Outlook Retrieves Emails But Fails to Put Then Into the Inbox

Len_Jacobson — Sun, 19 Apr 2026 17:32:24 GMT

I have a brand new Dell desktop that replaced a previous Dell desktop computer. I have rebuilt everything on the new computer that was on the old, but have a very strange problem with Outlook. When I click on "Send/Receive", I see at the bottom right of the screen that it is retrieving a bunch of emails from the Gmail server. But upon completion of the retrieval, none of those emails appears in the Inbox. If I click again on "Send/Receive", the process repeats. And since I have set up retrieval to automatically issue the "Send/Receive" every three minutes, this process repeats and repeats, never placing the retrieved emails into the Inbox. I should also comment that the count of the emails only increases, telling me that those emails do not disappear from the server.

I am using POP3, not IMAP. I am using Outlook Classic, not the new Outlook.

I have been using Outlook for many, many years, and have successfully set up Outlook many, many times. But I am totally baffled by what I am seeing.

I would appreciate any suggestions at all.

Thank you.

Outlook not removing junk emails from one sender

bschmidt51 — Sat, 18 Apr 2026 15:41:09 GMT

I'm using Outlook 2016 on Windows 11. Beginning on Feb 17, my email spam folder started blowing up with about 40+ spam emails per day, all on "fake medical" topics -- attempting to sell cures for every medical condition that you can think of, and some you would never think of. Then after a couple of weeks, some of them started appearing in my Inbox, not caught by the spam filter. So, I raised my Junk email filter level to High. And whenever an unwanted email still gets through to my Inbox, I put the sender on the Outlook "block sender" list.

But emails from one particular sender keep getting through to the Inbox, no matter how many times I block the address. What else can I do?

Personal Microsoft account security code

ncsyadav — Fri, 17 Apr 2026 20:35:16 GMT

Dear Microsoft Outlook Support Team,

I am currently facing an issue while trying to reset my Outlook account password. I have forgotten my password and attempted to reset it, but I am encountering problems during the verification process.

The system is asking for mobile verification codes multiple times, and I am receiving an error message stating that the service is not available. Because of this, I am unable to complete the password reset process.

I kindly request you to assist me in resolving this issue and help me regain access to my account as soon as possible.

Thank you for your time and support.

I Can't Permanently Delete Emails From Shared Mailbox

OverwatchMedia — Fri, 17 Apr 2026 15:34:42 GMT

Anyone else had this issue and fixed it? In the outlook desktop app, I deleted mail from my shared mailboxes inbox and sent folder too I believe. In my shared mailbox, under the deleted folder, I select all the messages and click empty folder to try and permanently delete these emails, but then it just readds it back to the shared mailbox's deleted folder. It also creates a copy in my personal account's deleted folder, and when I delete it from there permanently, it still shows in the shared mailbox's deleted folder.

How can I fix it so I can get rid of these undeletable emails in my shared mailboxes deleted folder?

Outlook Classic "hangs" if I want to open attachments

Torzen — Thu, 16 Apr 2026 19:28:12 GMT

I have outlook classic on 3 PCs. Within the last month, I have noticed that it takes an incredibly long time to open attached files. Outlook "hangs" for up to 1 minute, and then the file opens. The same thing happens if I copy a file from one email to another.

Does anyone have an idea what is causing this. It is quite annoying

Conditional Formatting to New Outlook Calendar

RyanW- — Thu, 16 Apr 2026 13:10:23 GMT

Please bring Conditional Formatting to the New Outlook Calendar. This is a feature we have in Classic Outlook and something I use regularly to help maintain my organization. I've programmed it to color Work Time separate from Travel Time and various meeting categories so that visually I know a lot about the appointment just by the color.

"You've tried too many times to sign in with incorrect account or password"

ArtyMuse — Wed, 15 Apr 2026 17:28:01 GMT

Over the last 2 weeks or so, I have been receiving this message when I log into my email account. I haven't been logging in with the wrong information - I have been very careful. The message appears when I sign in via my lap-top and my mobile phone. I have even changed my password and cleared cache. It is causing me significant problems. What is the solution, other than waiting 24-48hrs for it to rectify itself? Thank you.

Will Microsoft ever provide a viable email client again?

philip42h — Wed, 15 Apr 2026 10:49:21 GMT

I'm a long time user of Outlook - from long before it became Classic. It was a perfectly viable email client - not perfect but useable.

I tried New Outlook when it was first promoted, and quickly switched back because it was functional deficient at the time.

Since then, Microsoft have introduced issues into Classic Outlook - specifically:

It can't maintain a set Office theme. I can set a theme (the Microsoft default system setting) but it corrupts and highlights in black (for example) after a short while. (I believe after the PC switches off the screen or the PC sleeps)
It 'corrupts' while composing longer emails meaning that I cannot send or save the draft but must start again from scratch.

I tried new Outlook again - it's not as bad as it was - but:

It still doesn't allow me to present my email accounts in the order that I want to see them.
It doesn't manage Contacts and Contact Lists correctly - while Classic Outlook does.

So I now have my PC set-up to use both Classic and New Outlook and have to switch between them depending on what I need to do ... 🤷‍♂️😠

My requirements aren't trivial, but they are not that complicated:

I need to manage multiple email accounts - around 10 in all. I want to be able to present them in my 'most used' order - i.e. I want the ability to sort the order of accounts.
I have a Microsoft account that I use to log-in to my PC etc.
My default email account is Gmail
My default calendar account is Microsoft
I want a single default set of Contacts and Contacts lists that I can use in conjunction with any of my ten email accounts
I want my email client to be stable

Is that too much to ask? And why, oh why, can't Microsoft deliver such a solution?

Inserting tables and formatting in Outlook for web

damian_connolly — Wed, 15 Apr 2026 09:50:05 GMT

Please could anyone help with the problem of inserting tables into an e-mail message in the web version of Outlook?

The previous workaround of converting the message to HTML has been removed by Microsoft.

Now the insert table is permanently greyed out (along with other formatting buttons) There does not seem to be any way of converting the message from plain text to HTML.

This is proving to be really frustrating, so any help from the community would be very much appreciated.

Outlook login - temporary problem with recovery service

newshawlane — Tue, 14 Apr 2026 13:08:03 GMT

Hi,

Sorry if this is the wrong place in advance, I have had my hotmail.com account probably since circa 1998 and it has everything on there.

It seems someone has tried to login so many times that suspicious activity has been detected, I have tried many ways to recover it.

I have 2FA Switched on but when I try password recovery to get it to text my mobile it states that service is unavailable :-(

It will email to my 1st alternate email account however it then asks to use the second one to which was an old work account that I have no access to :-(

Any ideas? do I just wait until it unblocks my phone number?

I have the 25 digit recovery key but I get the below error. All help welcome as I really need my account back!

'You've tried to sign in too many times with incorrect account/password'

CirrusSR22 — Mon, 13 Apr 2026 14:59:32 GMT

I am continuing to get a 'You've tried to sign in too many times with an incorrect account of password' error despite recently changing my password. The only way around this is to use my cell phone address to sign in vs. my email address.

What do I need to do to 'reset' my account to not have this error message?

Thanks
