By providing excellent features and incredible functionalities, Microsoft 365 has gained a remarkable position in the market as a collaboration and productivity platform. This cloud Office 365 platform is extremely secure for data too. It helps users store and edit enterprise-level data and allows them to share and collaborate with others via advanced collaboration tools and applications, irrespective of their geographical locations.

Microsoft 365 has always inspired businesses to move to the cloud since its launch in 2011. Though it provides multiple subscription plans, affordable pricing, and a set of applications that allow users to communicate and collaborate, Microsoft 365 still lacks at some points. There are some common problems that many Microsoft 365 users often face while using it.

In this article, we will highlight some of the office 365 known issues and their solutions that are often encountered by users in Microsoft 365.

  1. Sign-in problems with Microsoft 365

    Sometimes if users are unable to sign in to Microsoft 365 portal, there could be two reasons behind this problem – either the password is wrong, or the service that handles log-ins is not supportive. Don’t worry! This error can be fixed easily.

    As most of you might know, Microsoft 365 Home and Personal license rely on your Microsoft account. So, your Microsoft 365 ID and password must match with your Microsoft 3655 account. Make sure you are typing the correct credentials for your account.

    If the problem persists, then click the Can’t access your account link on the Microsoft 3655 log-in portal. The password reset guide will help you how to verify and change your password.

  2. Synchronization errors with Microsoft 365

    First, let us explain what Microsoft 365 synchronization problem is. When you open any of the Microsoft 365 applications like Word, Excel, or PowerPoint, recently added files must appear in every application whenever you open them, but if that doesn’t happen, then there are synchronization problems with Microsoft 365.

    Well, it’s infrequent with desktop version, mobile users often face this problem a lot. In such cases, you should close the app immediately and re-open it. However, if the problem still occurs, it means the file has never synchronized with OneDrive, which means your system is not connected properly to the Internet. So, check your Internet connection, and then check for files.

  3. Difficulty in getting support

    When we take a service or plan, we expect a hundred percent technical support from the vendor. But, with Microsoft 365, users don’t get the support that they want. We don’t mean that Microsoft doesn’t provide any assistance, but it doesn’t facilitate any support system to deal with every support request. So, if you have a query related to Microsoft 365, then you’ll have to wait for some days to get an efficient solution.

    The only other solution that you can use is to take help from an external IT support service provider or use a third-party tool to fix your issues.

  4. Bandwidth demand

    High bandwidth demand for Microsoft 365 often becomes the most challenging thing for users. While working online with Microsoft 365, users need sufficient bandwidth to keep the workflow maintained, especially while managing a lot of files in OneDrive. One way to get out of this situation is by contacting your internet provider and asking for higher bandwidth plans.

  5. Microsoft 365 isn’t 100% cloud-based

    Most of you know Microsoft 365 as a 100% cloud-based platform, but some apps of Microsoft 365 are not available in the cloud, like MS Access and Publisher. Now, it is up to your bandwidth, which type of Office apps you use – desktop or cloud. Because businesses with lower bandwidth will end up using the desktop version of Office apps.

  6. It is not easy to migrate to Microsoft 365

    While all other office 365 known issues could be resolved quickly, performing the migration to Microsoft 365 is one of the worst nightmares for users. While migrating to or from Microsoft 365, users face a lot of difficulties, such as:

    • Migrating all types of data- Exchange data, SharePoint data, OneDrive data, IMAP data, etc.
    • Difficulty in performing the migration using manual methods
    • Requirement for technical experts for migration
    • Need for selective migration
    • Ambiguity is estimating migration time and feasibility
    • Finding a good professional Office 365 Migration tool.
    • Assigning impersonation rights to users mailboxes

    With these obstacles, it is almost impossible for non-technical users to perform the migration in Microsoft 365.
